Title: Paved surface reconditioning system

Description:
BACKGROUND OF THE INVENTION 
     Modern road surfaces typically comprise a combination of aggregate materials and binding agents processed and applied to form a smooth paved surface. The type and quality of the pavement components used, and the manner in which the pavement components are implemented or combined, may affect the durability of the paved surface. Even where a paved surface is quite durable, however, temperature fluctuations, weather, and vehicular traffic over a paved surface may result in cracks and other surface or sub-surface irregularities over time. Road salts and other corrosive chemicals applied to the paved surface, as well as accumulation of water in surface cracks, may accelerate pavement deterioration. 
     Road resurfacing equipment may be used to mill, remove, and/or recondition deteriorated pavement. In come cases, heat generating equipment may be used to soften the pavement, followed by equipment to mill the surface, apply pavement materials, and plane the surface. Often, new pavement materials may be combined with materials milled from an existing surface in order to recondition or recycle existing pavement. Once the new materials are added, the materials may be compacted and planed to restore a smooth paved surface. 
     U.S. Pat. No. 4,793,730 which is herein incorporated by reference for all that it contains, discloses a method and apparatus for renewing the surface of asphaltic paving at low cost and for immediate reuse. The asphalt surface is heated to about 300.degree.-500.degree. F. The surface is broken to a depth of about two inches and the lower material thoroughly mixed in situ with the broken surface material. After mixing, the material is further heated to fuse the heated mixture into a homogeneous surface. The surface is screeded for leveling and compacted by a road roller. A road machine is disclosed having a steam manifold for heating the asphalt, transversely reciprocating breaker bars having teeth adjusted to the depth desired, toothed mixing cylinders for mixing the broken material, and a second steam manifold for reheating the mixed material. Reciprocating screed bars on the road machine level the mixed and heated material. Final compacting may be done with a conventional road roller. 
     U.S. Pat. No. 4,261,669 which is herein incorporated by reference for all that it discloses, teaches a method and apparatus for repairing asphalt concrete road surfaces wherein a tractor a steam box and a car mounted with a screw cutter are coupled in this order and a series of linearly operated equipment is used on the asphalt concrete paved road surface, including a heater car, an asphalt finisher and a road roller in this order after the car. Each of the equipment is made to advance at low speed and the asphalt concrete paved road surface is artificially heated by the steam box to impart fluidity to the road surface, after which it is cut with the screw cutter and the cut asphalt concrete is conveyed into a heating chamber of the heater car, and water content in the asphalt concrete is removed by heating and stirring. The resulting asphalt concrete is adjusted to an optimum temperature suitable for asphalt concrete paving, and then is discharged from the heating chamber, and charged onto the surface of the cut road directly and thereafter the asphalt concrete paved road surface is treated by using the asphalt finisher and the road roller. 
     U.S. Pat. No. 5,486,554 which is herein incorporated by reference for all that it contains, discloses that a low cost method for preparing foamed or aerated asphalt-rubber paving compositions is provided wherein a flowable mixture including respective quantities of asphalt and finally divided reclaimed rubber particles is first directed into a rocket-type reactor along with steam and/or water, thereby subjecting the mixture to conditions of elevated temperature, pressure and shear. Thereafter, the initially reacted mixture is passed into a pressurized, secondary reaction vessel system in order to complete the gelation reaction in a period of, e.g., 7-15 minutes. The preferred apparatus includes; a rocket-type primary reactor presenting a confined reaction zone; asphalt-rubber and water/steam conduits communicate with the zone. The output of the primary reactor feeds directly into a pressurized tank forming a part of the downstream secondary reaction and recovery system, where the gelation reaction is completed. The preferred system includes a total of five serially interconnected tanks housed within an insulative shell and heated by means of burner.

     DETAILED DESCRIPTION OF THE INVENTION AND THE PREFERRED EMBODIMENT 
     In this application, “pavement” or “paved surface” refers to any artificial, wear-resistant surface that facilitates vehicular, pedestrian, or other form of traffic. Pavement may include composites containing oil, tar, tarmac, macadam, tarmacadam, asphalt, asphaltum, pitch, bitumen, minerals, rocks, pebbles, gravel, polymeric materials, sand, polyester fibers, Portland cement, petrochemical binders, or combinations thereof. Likewise, rejuvenation materials refer to any of various binders, oils, and resins, including bitumen, surfactant, polymeric materials, emulsions, asphalt, tar, cement, oil, pitch, or combinations thereof. Reference to aggregates refers to rock, crushed rock, gravel, sand, slag, soil, cinders, minerals, or other course materials, and may include both new aggregates and aggregates reclaimed from an existing roadway. Likewise, the term “degrade” or “degradation” is used in this application to mean milling, grinding, cutting, ripping apart, tearing apart, exploding apart, forcing apart, or otherwise taking or pulling apart a pavement material into smaller constituent pieces. 
     Referring to  FIG. 1 , in selected embodiments, a motorized vehicle  100  may include a shroud  104 , covering various internal components of the motorized vehicle  100 , a frame  105 , and a translational element  106  such as tracks, wheels, or the like, to translate or move the vehicle  100 , such translational element being well known to those skilled in the art. The motorized vehicle  100  may also include means  107  for adjusting the elevation and slope of the frame  105  relative to the translational element  106  to adjust for varying elevations, slopes, and contours of the underlying road surface. 
     In one embodiment the vehicle may comprise a actuator  108  intermediate the vehicle  100  and a press plate  109 . The press plate  109  may have a working surface  110  with at least one nozzle  111  disposed therein. At least a portion of the working surface  110  may be adapted to contact a paved surface. In the current embodiment multiple nozzles  111  are disposed on the working surface  110  of the press plate  109 . The nozzles  110  may be in communication with a fluid reservoir  112  that may store rejuvenation materials such as bitumen, tar, oil, water, resins, binding agents, waxes, synthetic clay, maltenes, asphaltenes, surfactants, sand, grit, and combinations thereof. The fluid reservoir  112  may also heat and pressurize the stored rejuvenation materials. To maintain pressure under the press plate  109  and prevent leakage of rejuvenation material the press plate  109  may have a sealing element  113  on at least one side  114  adapted to engage the paved surface. In the present embodiment the press plate  109  has two sealing elements  113  on its sides  114  comprising carbide strips  115  along the length of the press plate  109 . 
     The nozzle may comprise be made of a steel, stainless steel, or a hardened steel. Preferably, the nozzle is made out of a material comprising a hardness greater than 58 HRc, such as tungsten carbide or diamond. Suitable materials for the nozzle include diamond, natural diamond, polycrystalline diamond, cubic boron nitride, vapor-deposited diamond, diamond grit, polycrystalline diamond grit, cubic boron nitride grit, chromium, tungsten, titanium, molybdenum, niobium, a cemented metal carbide, tungsten carbide, aluminum oxide, zircon, silicon carbide, whisker reinforced ceramics, diamond impregnated carbide, diamond impregnated matrix, silicon bonded diamond, or combinations thereof. The inner diameter of the nozzle is preferably less than 1 mm. In some embodiment, the inner diameter is between 1 to 1,000 microns. Preferably the inner diameter is 0.001 to 0.008 inches. In some embodiments, the a nozzle density on the press plate is 1 nozzle per square inch. In other embodiments, the nozzle density may be 1-7 nozzles per square inch. 
     The nozzles  110  are adapted to inject the rejuvenation material into the paved surface while the press plate  109  compresses against the paved surface. The nozzles  110  should inject the fluid into the paved surface at such a temperature and/or pressure that the binder bonding the aggregate in the paved surface melt and/or erode allowing the rejuvenation material to rebind the aggregate together. In some embodiments, the press plate  109  will provide enough pressure to the paved surface that the area of lowest pressure for the rejuvenation material to flow into will be within the pavement. The press plate  109  may provide pressure long enough that the rejuvenation material diffuses in-between all of the aggregate. Preferably, the injection pressure is not sufficient to erode or damage the individual pieces of aggregate. Preferably, there are sensors mounted on the vehicle  100  which sense the subsurface condition of the paved surface, including the extent and depth of damage to the paved surface. In areas where the damage is comparatively deep, the press plate  109  may provide pressure longer to allow the rejuvenation material to migrate deeper into the paved surface. 
     The motorized vehicle  100  may also comprise a compaction element/elements  116  selected from the group consisting of rollers, tampers, plates, vibrators and combinations thereof. The working surface  110  of the press plate  109  may press against the paved surface while the nozzles  111  inject rejuvenation material into the paved surface. The surface may soften and the aggregates may loosen because of the temperature and pressure of the injected material. During this process the aggregates within the paved surface may also be recoated with rejuvenation material. In the present embodiment the compaction element  116  is a roller  117 . The roller  117  may be placed after the press plate  109  so that the loosened and/or softened mix may be recompacted to a desired density. The vehicle  100  may also include a tank  118  for storing hydraulic fluid, a fuel tank  119  and a hopper  120  for storing aggregate such as gravel, rock, sand, pebbles, macadam, concrete, or the like. 
       FIG. 2  is a diagram of a side view of an embodiment of a mobile vehicle  100  for reconditioning a paved surface  200 . The actuator  108  may comprise hydraulic actuators, motors, pumps, solenoids, piezoelectric devices, magnetostrictive devices, electric actuators, smart material actuators, and combinations thereof capable of raising and lowering the press plate  109 . The press plate  109  may be lowered so that the working surface  110  is in contact with the paved surface  200 . The actuator  108  may be controlled such that varying amounts of pressure may be applied to the paved surface  200  by the press plate  109 . In one embodiment the press plate  109  may apply enough pressure to the paved surface  200  to prevent the paved surface  200  from expanding upwards when injected with the pressurized fluid. The applied pressure may also be sufficient to prevent the press plate  109  from disengaging the paved surface  200 . 
     As the vehicle  100  moves along the paved surface, the paved surface  200  under the press plate  109  may become pressurized. Once the press plate moves off of a pressurized portion of pavement  200 , the pavement  200  may release the pressure by expanding. After expansion the pavement  200  may be recompacted using a compaction element  116 . In the present embodiment the compaction element  116  is a roller  117 . The roller  117  may comprise a sensor  201  such as a density sensor so that the density of the pavement  200  may be measured and the pressure applied by the compaction element  116  adjusted until a desired density is achieved. 
       FIG. 3  is a perspective diagram of an embodiment of a motorized vehicle  100  for on site reconditioning of a paved surface. The press plate  109  of the current embodiment may comprise an expansion chamber  300  on the working surface  110  after one or more rows  301  of nozzles  111 . As the expansion chamber moves over the areas of the paved surface which were formerly held in by the press plate, the aggregate will explode into the expansion chamber due to an unequal distribution of pressure. In some embodiments during the explosion, oil based rejuvenation material which were injected into the paved surface may coat all of the surfaces of each aggregate. In other embodiments, oil based rejuvenation materials may be sprayer, misted or otherwise added into the paved surface mix while it is expanded in the expansion chamber. Preferably, the press plate moves fast enough so that the explosion occurs before the heat from the hot rejuvenated material is absorbed into the aggregate. This process may only require that the surface of the aggregate be exposed to the heat. The expansion chamber  300  may comprise vents  302  to release the moisture from the pavement or from the rejuvenation material. It is believed that in this process, that the aggregate may not be required to be heated. The aggregate in some roads may be roughly 94 percent or more of the road. In some embodiments, the system of the present invention may only need to heat six percent of the road, realizing significant energy and environmental saving compared to typical road resurfacing methods. 
     The press plate  109  may also comprise a beveled or curved front edge  303 . This may allow the press plate  109  to ride smoother upon uneven or sloped surfaces. The expansion chamber  300  may be a U-shaped trough, trapezoidal, rectangular, triangular, curved, or combinations thereof. In one embodiment the expansion chamber  300  may be formed in the working surface  110  of the press plate  109  such that it releases at least a portion of the pressure in the paved surface. 
       FIG. 4  is a side diagram of an embodiment of a portion of a motorized vehicle  100  for reconditioning a paved surface  200 . In the current embodiment the nozzles  111  may inject rejuvenation fluid at a constant temperature and pressure into the paved surface  200 . Other embodiments may include pulsing rejuvenation fluid into the paved surface  200  at varying frequencies and patterns. As the vehicle  100  moves along the paved surface  200  the pressure and temperature may continue to increase within the paved surface  200  until reaching the expansion chamber  300 . As the expansion chamber  300  moves over a portion of pressurized pavement  200 , the pavement  200  may explode within the chamber  500  separating the aggregate of the paved surface  200  from each other. By separating the aggregate, the binder coating each aggregate may be exposed to the heat and at least partially melt. In some embodiments, the separating of the aggregate will also allow the binder coating each aggregate to be exposed to the rejuvenation material that was injected into the pavement  200  or rejuvenation material that is added in the expansion chamber  300 . The paved surface  200  may explode such that some of the aggregate come off in clumps, but preferably each aggregate is separated from each other. This may be controlled by the pressure and the temperature with which the fluid is injected. After the explosion of the pavement  200  the back edge  402  of the expansion chamber  300  may act as a screed and smooth out and/or compact the loosened material  400 ,  401 . A compaction element  116  may be placed close behind the press plate  109  to compact the chunks  400  and constituent pieces  401  to a desired density. 
       FIG. 5  is a cross sectional diagram of an embodiment of a motorized vehicle  100  for reconditioning a paved surface  200 . The expansion chamber  300  may comprise a vent  302  to release excess moisture (or steam  650 —see  FIG. 6 ) from the paved surface  200 . The moisture may have been injected as at least a portion of the rejuvenation material, or the moisture may be residual moisture that was already present in the paved surface  200  before the conditioning process started. The moisture may be steam and it may collected and be condensed back to a liquid by a condenser  500 . In one embodiment the condensed liquid may be passed back into the reservoir  112  with the other rejuvenation fluid. Alterations of this embodiment may include passing the condensed liquid into a water reservoir  112  for holding. The majority of the fluid may be water which may be pressurized and heated in the water reservoir  112 . A separate reservoir  501  may be used to store and pressurize oil and other rejuvenation materials to be injected into the pavement  200 . Water may be mixed with a binder such as bitumen under pressure before they are injected into the paved surface  200 . Preferably the temperature is adjusted such that the water will be evaporated in the expansion chamber  300  while the bitumen and/or other components of the rejuvenation material will not evaporate but will remain in the paved surface  200 . 
     In selected embodiments an actuator  502  may apply a desired force to the back end  202  of the press plate  109 , such that the back end  202  of the plate  109  compacts the loosed aggregate back into a reconditioned paved surface. The actuator  502  may be a hydraulic cylinder, electric actuator or any other form of actuator known in the art. The back edge  402  of the expansion chamber may comprise a hardened insert  503  such as a tungsten carbide insert, or a polycrystalline diamond insert. The insert  503  may help prolong the life of the back edge  402  of the expansion chamber  300  when used to level out the loosened pavement  200 . The beveled or curved front end of the press plate  109  may also comprise a hardened insert  503  to prolong its life. Preferably, the hardened insert  503  comprises a hardness of at least 58 HRc. Other possible materials may include hardened steel, hard facing, cubic boron nitride, and other ceramics and/or composites. 
       FIG. 6  is a cross sectional diagram of an embodiment of a motorized vehicle  100  adapted to recondition a paved surface  200 . The front edge  303  of the press plate  109  may comprise a seal  113  to prevent the injected fluid from leaking between the paved surface  200  and the pressure plate  109 . The seal  113  may be formed by machining a series of groves  600  and ridges  601  on the working surface  110  of the plate  109 . Alternately, an insert  602  with groves  600  and ridges  601  may be brazed into a recess  603  in the working surface  110  of the press plate  109 . Variations of the present embodiment may include placing an insert  602  of carbide or other hard material into a recess  603  on the front end of the press plate  109 . The hard insert  602  may extend beyond the working surface  110  of the press plate  109 . With the insert  602  extending beyond the working surface  110  the amount of force to the region  604  of pavement  200  underneath the hard insert  602  may exceed that of the pavement  200  underneath the rest of the plate  109 . This may help prevent the leaking of rejuvenation fluids being injected. 
     The expansion chamber  300  may comprise an aggregate dispenser  605 . The aggregate dispenser  605  may dispense aggregate  606  at a desired rate or be control by a feedback network (not shown) that is capable of determining the proper ratio within the pavement  200  and add aggregate  606  accordingly. The expansion chamber  300  may also comprise at least one nozzle  110  for dispensing oil and other rejuvenation fluids. The nozzle  110  for rejuvenation fluids may be able to coat portions of the aggregate  606  that may have been missed by the injected rejuvenation material The rejuvenation fluids dispensed in the expansion chamber  300  may be sprayed or misted at a constant rate or be sprayed according to feedback from sensors (not shown). 
       FIG. 7  is a perspective diagram of an embodiment of a motorized vehicle  100  adapted to recondition a paved surface  200 . In the current embodiment, to facilitate reconditioning of a swath of pavement wider than the motorized vehicle  100 , the vehicle  100  may include one or more slidable carriages  700  supported by a bearing surface  701  of an underside  702  of the motorized vehicle  100  capable of extending beyond the outer edge of the vehicle  100 . In some embodiments, the carriages  700  may be as wide as the vehicle  100  itself, the carriages  700  may sweep over a width approximately twice the vehicle width  703 . The carriages  700  may comprise an actuator  108  in mechanical communication with a press plate  109 . The carriages  700  may allow for movement of the press plate  109  both parallel and perpendicular to the length of the motorized vehicle  100  or combinations thereof. The actuator  108  may allow for the press plate  109  to be moved vertically with respect to the paved surface  200 . The slidable carriages  700  may further comprise a row  704  of compacting elements  116 . Under the shroud  104 , the motorized vehicle  100  may include an engine and hydraulic pumps for powering the actuator  108 , the carriages  700 , condensers, pressuring mechanisms or other components. The vehicle  100  may also include a reservoir  112  for storing and pressurizing the rejuvenating fluids. 
       FIG. 8  is a cross sectional diagram of an embodiment of the press plate  109 . In the current embodiment the press plate  109  is adapted to comply with the paved surface  200 . Many paved surfaces  200  may not be completely flat. The upper surface  800  of the press plate  109  facing the underside  702  of the motorized vehicle  100  may be corrugated. The corrugations may allow the surface to comply with the paved surface  200  by bending at the grooves  801 . Actuating elements  802  may be attached to the ridges  803  of the corrugated surface  800 . This may allow the rigidity of the press plate  109  to be controlled based on the pressure applied by the actuating elements  802 . The actuating elements  802  may be placed on every ridge  803  of the corrugated surface  800  as shown in  FIG. 8  or at a desired interval such as every other ridge  803  (not shown). The working surface  110  of the press plate  109  may comprise a nonstick and/or scratch resistant coating  804  selected from the group consisting of Fluoropolymers, Teflon®, diamond, carbide, carbon coatings, cubic boron nitride, and combinations thereof. The life span of the working surface  110  may be increased by reducing the amount of scratches and preventing aggregate  606  and rejuvenation fluids from sticking to the press plate  109 . 
       FIG. 9  is a cross sectional diagram of an embodiment of the press plate  109 . In the current embodiment the press plate  109  is adapted to apply enough pressure to the paved surface  200  to cause the surface  200  to comply with the working surface  110  of the press plate  109 . The front edge  303  of the press plate  109  may be rounded and/or angled up to help the paved surface  200  comply with the working surface  110 . In the present embodiment the fluid nozzles  111  may be set to inject at varying pressures and temperatures. The first row  301  of nozzles  111  running perpendicular to the length of the vehicle may be set to have the lowest pressure. The pressures with which the rejuvenation material is injected may progressively increase from the first row  301  to the last row  900 . In other embodiments the pressure may be adjusted from high pressure to low pressure starting at the first row  301  and ending on the last row  900 . The pressures and temperatures may be adjusted depending on the paved surface  200  conditions and the desired results. 
     The press plate  109  may also comprise one or more sensors  201  selected from the group consisting of temperature sensors, pressure sensors, position sensors, density sensors, compressive strength sensor, porosity sensor, pH sensor, electric resistively sensor, inclination sensor, nuclear sensor, acoustic sensor, velocity sensor, moisture sensor, capacitance sensor, and combinations thereof. The sensors  201  may be used as part of a closed loop system used to maintain a constant pressure underneath the press plate  109 . A pressure sensor  109  may measure the pressure of the paved surface  200  as the rejuvenation fluid is being injected and communicate the measured values to a controller  901 . If the pressure of the paved surface  200  goes higher or lower than a desired pressure, the controller  901  may send a signal to adjust the pressure with which the rejuvenation fluid is being injected. If the pressure is too low, the controller  901  may adjust the nozzle  111 , and or fluid reservoir  112  to inject the fluid at a higher pressure and/or temperature. 
       FIG. 10  is a diagram of an embodiment of the working surface  110  of the press plate  109 . The nozzles  111  on the press plate  109  may be independently controllable allowing only a portion of the nozzles  111  to be on at any given time. If a portion of the paved surface  200  may not be reconditioned due to an obstacle  1000  such as a railroad crossing (not shown) or a manhole  1001 , the fluid nozzles may be turned off for a portion of time until the obstacle  1000  is passed.  FIG. 11  diagrams an alternate embodiment of the working surface  110  of the press plate  109 . The injection system may be controlled digitally such that nozzle  111  may be controlled individually. Preferably, each nozzle  111  pulses the rejuvenation material into the paved surface  200  when commanded by a closed loop system. Pulsing may allow greater control of the flow of rejuvenation material since?. In other embodiments, the nozzles  111  may continuously inject fluid into the paved surface  200 . Preferably, there are two rows of nozzles  111 , which are offset from each other. 
     As in  FIG. 10 ,  FIG. 11  diagrams the press plate  109  with only a portion of the nozzles  111  injecting fluid. This spray pattern may be beneficial when only a portion of the paved surface  200  may be in need of reconditioning. In the current embodiment the nozzles  111  may be turned on around the portion  1100  of the paved surface  200  that has received a greater amount of wear and tear. Such portions  1100  of the paved surface  200  may be areas where the tires of an automobile are most commonly in contact with the pavement  200 . In such embodiments the nozzles  111  may controllably inject rejuvenation fluids to the portions  1100  of the paved surface  200  that need reconditioning which may be determined through a closed loop system. In one embodiment, nozzles  111  may inject a greater volume of rejuvenation material into the portions  1100  of pavement  200  more worn and decrease the amount of rejuvenation material injected into portions  1101  on the paved surface that are less worn. Many variations of injection patterns may be used and should not be limited to those shown but other patterns obvious to one skilled in the art. 
       FIG. 12  is a cross sectional diagram of an embodiment of a press plate  109  comprising multiple sealing elements  113 . In the present embodiment the sealing elements  113  are carbide strips  115  placed on the two sides  114  of the press plate  109  that run parallel with the length of the motorized vehicle  100 . Because the carbide strips  115  may extend beyond the working surface  110  they may apply a greater amount of pressure upon the regions  1201  of pavement  200  in contact with the carbide strips  115 . Or in other words, the volume  1201  beneath the sealing elements  113  will be more compressed then the volume  1202  beneath the press plate  109 . Because the volume  1201  underneath the sealing elements  113  has a higher pressure, the volume  1202  under the press plate  109  will be the path of least resistance for the rejuvenation material. This may contain the rejuvenation material underneath the press plate  109 . The strips  115  may extend beyond the working surface  110  by a distance  1200  sufficient to generate enough pressure in the volume  1201  of pavement  200  below the strips  115  to keep the majority of the injected rejuvenation fluid in the volume of pavement  1202  below the press plate  109 . In one embodiment the strips  115  extending distance  1200  may be adjustable so that the strips  115  extend further for higher injection pressures and less for lower injection pressures. In other embodiments the strips  115  may be removable inserts (not shown) that may be easily replaced or adjusted to correspond with different conditions. 
       FIG. 13  is a cross sectional diagram of an embodiment of a press plate  109  comprising an edge packer  1300 . In the current embodiment the pavement reconditioning vehicle  100  may be used to recondition a paved surface  200  with at least one pavement edge  1301 . The pavement edge  1301  may be rounded, flat, beveled, or have any other edge known in the art. In the current embodiment the edge  1301  of the pavement  200  is beveled down at an angle. The edge packer  1300  may be attached to the motorized vehicle  100  through an actuator  1302 . The bottom face  1303  of the edge packer  1300  may be beveled or curved to correspond with the edge  1301  of the paved surface  200 . The edge packer  1300  may be adapted to apply a sufficient pressure to the edge of the paved surface  200  to prevent the edge  1301  from expanding out due to the high pressure from the injection of the rejuvenation material. The edge packer  1300  may also help maintain a constant pressure within the paved surface  200  by creating a dense region  1304  of pavement with a higher resistively to the pressurized fluid. The opposing side  1305  of the press plate  109  may also comprise a sealing element  113 . Variations from the present embodiment may include using one or more rollers (not shown) adapted to roll along the edge  1301  of the paved surface  200  next to the press plate  109 . 
       FIG. 14  is a cross sectional diagram of an embodiment of a press plate  109  comprising an edge saw  1400 . The saw  1400  may perform a similar function to the edge packer  1300  described in  FIG. 13 . The edge saw  1400  may be used at transitions in the paved surface  200  such as a change of material or structure. In the current embodiment the sides  1401  of the paved surface  200  may comprise a transition  1401  such as a cement curb, sidewalk or gutter. To prevent pressure from escaping out the side of the press plate  109  near the transition  1402 , the edge saw  1400  may cut along next to the press plate  109 . The saw  1400  may help prevent the pressure from the injected fluid from escaping from underneath the press plate  109  by creating a barrier to the pressure. If the pressure is allowed to escape from under the press plate  109  the volume of material underneath the transition  1402  may become pressurized and expand. This form of expansion may crack, misalign, and dislodge the cement curb, sidewalk and or gutter. 
       FIG. 15  is a perspective diagram of an alternate embodiment of a portion of a motorized vehicle  100  adapted to recondition a paved surface  200 . In the current embodiment the press plate  109  may comprise two or more staggered rows  301  of nozzles  111 . The press plate  109  may further comprise an expansion chamber  300  with release vents  302 . The sealing elements  113  on the press plate  109  may comprise one or more rings  1500  secured around one or more pulleys  1501 . The pulleys  1501  may spin freely or the spinning may be controlled by a motor (not shown). As the motorized vehicle  100  moves along the paved surface  200  a section of the ring  1500  may come into contact with the paved surface  200 . The section of ring  1500  may maintain contact with the same area of pavement  200  until the back end  202  of the press plate  109  is reached. At the back end  202  of the press plate  109  the ring  1500  may begin to come off of the paved surface  200  and follow the pulley  1501 . The sealing element  113  of the present embodiment may last longer because it is applied and lifted from the paved surface  200  instead of being dragged along the paved surface  200 . 
       FIG. 16  is a cross sectional diagram of an embodiment of the injection nozzles  111  and the press plate  109 . In the present embodiment multiple nozzles  111  are disposed within the press plate and in communication with a supply line  1600 . A check valve assembly  1601  may be disposed between the supply line and the nozzle. The check valve assembly  1601  may comprise a chamber  1602  intermediate an inlet  1603  and an outlet. The chamber  1602  may comprise a spring  1604  which is adapted to push a ball  1605  against the inlet  1603  to seal it from allowing fluid through. The ball  1605  may be forced down into the chamber  1602  when the fluid from the supply line  1600  reaches a sufficient pressure to compress the spring  1604 . With the spring  1604  slightly compressed the fluid coming from the supply line  1600  may flow around the ball  1605  through the chamber  1602  and out the nozzle  111 . The supply line  1600  may be connected to the fluid reservoir (not shown) and may be able to handle a high pressure and high temperature. A piston  1606  may be placed along the pathway  1607  to the inlet  1603  to increase the pressure to a high enough pressure to open the check valve assembly  1601 . The piston  1606  may be placed along the supply line  1600  such that the supply line  1600  to the reservoir (not shown) is closed as the piston  1606  is actuated. This may allow a fixed volume of fluid to be pressurized as the piston  1606  is depressed. In the current embodiment it may be desirable to pressurize the fluid to a pressure between 3000 psi and 65000 psi. The nozzles  111  may comprise and inner diameter  1608  between 1 micron and 1000 microns. This may help control the amount of fluid injected into the paved surface  200  and maintain the desired pressure. The distance between adjacent nozzles may be anywhere from 0.1 to 1 inch Preferably in embodiments, where the rows of nozzles are offset, a nozzle may be 0.5 inches away from the closest adjacent nozzle and 0.75 inches away from the closest nozzle in the adjacent row. 
       FIG. 17  is a cross sectional diagram of an embodiment of the press plate  109  and fluid nozzle  111 . The present embodiment is a variation of the embodiment of  FIG. 16  with each of the nozzles  111  comprising an independent supply line  1600 . A piston  1606  and a check valve  1601  may be disposed within the supply line  1600  The press plate  109  may also comprise a heating element  1700  to maintain the paved surface  200  at a constant temperature. The heating element  1700  may be an electric heater, gas powered heater, or any other form of pavement/asphalt heater known in the art. The press plate  109  may heat up as the motorized vehicle  100  traverses the paved surface  200  injecting rejuvenation material. After the press plate  109  heats up, less energy may be required by the heating elements  1700  to bring the paved surface to a desired temperature. 
       FIG. 18  is a cross sectional diagram of another embodiment of the press plate  109  and fluid nozzle  111 . A cone  1800  is provided that is capable stopping the inlet  1603  from allowing the passage of fluid to the nozzle  111  in its closed position The fluid nozzle  111  may be formed from a ball  1801 . Preferably the ball  1801  is made of a hard durable material such a tungsten carbide, hardened steal, titanium, cobalt and other hard materials known in the art. Preferably the ball has a hardness of at least 58 HRc. A hole  1802  may then be made using electronic discharge machining (EDM) through the ball  180 . The hole may comprise a diameter of 1 micron to 1000 microns. Larger diameter holes  1802  may also be used if a larger volume of fluid is desired. The hole  1802  may then act as a nozzle  111  for the pressurized fluid when the pressure is high enough to open the check valve assembly  1601 . The ball  1801  may be connected to the plate  109  by threads or by brazing. 
     In some embodiments of the present invention, each time the pressure reaches the threshold to release the fluid, an automatic mechanism may push the entire nozzle towards the paved surface such that the nozzle slightly indents the paved surface before the fluid is released. In this manner the fluid may not have enough time to evaporate before it hits the paved surface and all of the fluid may be injected into the surface. 
       FIG. 19  is a diagram of an alternate embodiment of the press plate  109  and the fluid reservoir  112 . The press plate  109  comprises multiple rows  301  of nozzles  111  and sealing elements  113  on each side. The fluid reservoir  112  may be made up of one or more coils of electrically heated hose  1900 . The hose  1900  may be designed to withstand high pressures and high temperatures. In one embodiment the hose  1900  may comprise heating elements (not shown) within the outer sheath. The hose  1900  may be able to heat the fluid to a temperature above 500° F. In one embodiment the hose  1900  may be able to heat the fluid to a temperature between 250° F. and 700° F., preferably to 500° F. One such hose  1900  may include the electrically heated hose made by Applicator Systems Inc. whose size 3 hose (0.125″ inner diameter) is capable of operating at 3500 psi at 400° F. 
       FIG. 20  is a schematic of a rejuvenation fluid injection system  2000 . The system  2000  includes check valves  1601  intermediate fluid inlets  1603  and intensifiers  2001 . In one embodiment the fluid must exceed 300 psi at 450° F. to pass through the check valves  1601  and into the intensifiers  2001 . Once in the intensifiers  2001 , the fluid pressure may be increased up to a desired pressure. The fluid may then pass through a series of check valves  1601  and through nozzles  111  to the pavement. The first set  2002  of check valves  1601  may open at a low pressure such as 5 psi and may be used to ensure that fluid is not forced back into the intensifier  2001  by only allowing fluid flow in one direction. The second set  2003  of check valves  1601  may open around a pressure of 750 psi. Because the nozzles  111  may have such a small size opening for the fluid passage, the nozzles  111  may in part act as a limiter and help build pressure within the system. The pressure may increase between the intensifier and the nozzles until it reaches a pressure of up to 10000 psi. A pressure indicator  2004  may be in communication with the system  2000  to inform an operator of the pressure within the system  2000 . 
       FIG. 21  is a block diagram of a method  2100  for reconditioning a paved surface. The method  2000  may include the steps of applying  2101  a pressure to an area of a paved surface through a pressure transferring medium, the pressure transferring medium comprising at least one aperture with a nozzle; pressurizing  2102  a volume of the paved surface adjacent the area to another pressure by injecting a pressurized fluid into the volume while maintaining a pressure to the area of the paved surface; and controllably  2103  releasing the pressure to the area. 
     Whereas the present invention has been described in particular relation to the drawings attached hereto, it should be understood that other and further modifications apart from those shown or suggested herein, may be made within the scope and spirit of the present invention.
