Title: Soil Stabilization System and Method

Description:
TECHNICAL FIELD 
     The present disclosure generally relates to soil stabilization machines and, more particularly, relates to a system for the addition of dry additives and water directly to the mixing chamber of a stabilization machine during operation. 
     BACKGROUND 
     Soil stabilization is the process of mechanically or chemically improving the load-bearing capacity of soil or a ground surface. The process of soil stabilization may be required where roads are constructed for vehicular travel, as well as for building pads on which other construction may take place. In addition, soil stabilization may be useful in other applications, including surface mining, bio-remediation, agriculture and the building of high strength haul roads. 
     Stabilization machines such as rotary mixers typically include a frame quadrilaterally supported on traction units, an engine, an operator&#39;s station and a hood member under which a milling/mixing rotor is disposed, thereby forming an open bottom mixing chamber. A rotary mixer may be used as a soil stabilizer to cut, pulverize and mix native in-place soils with additives or aggregates that modify and stabilize the soil for a strong base. For example, dry additives such as fly ash, cement or lime may be incorporated into native soil during the stabilization process thereby increasing the general integrity of the soil. For stabilization purposes, a spreading machine is commonly used for dispensing dry additives in a layer directly over the base material or soil to be stabilized. Thereafter, a rotary mixer may pass over the coated base material to pulverize and mix the dry additive into the base material within the mixing chamber of the rotary mixer. 
     Dry additives used for soil stabilization purposes are typically powdery and light in nature. As a result, the stabilization method of disposing a layer of dry additive directly onto the base material before passing over the same with a stabilization machine tends to generate significant amounts of dust. This is especially true in windy conditions. Such increased dust levels at a worksite may cause undesirable conditions, such as impaired visibility within the site, diminished work machine performance and increased frequency of work machine maintenance. In addition, such dust levels may create uncomfortable work conditions for work personnel. Moreover, disturbance of the dry additive by the wind may ultimately negatively affect the amount of additive that is available for mixing with and stabilizing the soil. 
     Prior methods have been attempted to overcome these disadvantages of working with dry additives. For example, rather than using a spreading machine for depositing a layer of dry additive onto the base material in advance of the stabilization machine; the stabilization machine or rotary mixer itself may be equipped with an additive storage container mounted directly thereon. Such machines, having a built-in arrangement for spreading dry additives, directly dispose the additive onto the base material immediately before the mixing rotor travels over the additive and base material. However, as built-in storage containers are limited significantly with regard to the volume of dry additive they may contain, methods involving the dispersion of dry additives from such built-in storage containers require numerous refilling operations of the containers during a single stabilization process. Such methods therefore incur increased costs related to additional down time, energy consumption and personnel. Other methods involving spraying water over a disposed dry additive layer have also been attempted, however, these methods may present additional clean-up and disposal problems. Likewise, delivery of water to the mixing chamber of a stabilization machine has been employed, but fails to fully address the problems associated with dry additives. Accordingly, it would be beneficial to provide a soil stabilization system that directly delivers, proximate the mixing rotor of a stabilization machine, a relatively continuous supply of dry additive, thereby avoiding the above-described inefficiencies and undesirable working conditions, as well as dry additive loss. 
     SUMMARY 
     In accordance with one aspect of the present disclosure, a soil stabilization machine configured to mix a ground surface with dry additive and water is disclosed which may include a machine frame, a plurality of traction units configured to support the machine frame on the ground surface and a rotor coupled to the frame between traction units and configured to engage the ground surface. The soil stabilization machine may further include a mixing chamber at least partially defined by a hood and at least partially surrounding the rotor, a dry additive delivery system configured to blow a metered amount of dry additive under the hood and directly into the mixing chamber from a dry additive storage truck and a water delivery system configured to deliver a metered amount of water directly into the mixing chamber from a water storage truck. 
     In accordance with another aspect of the present disclosure, a soil stabilization system configured to mix dry additive and water with a ground surface is disclosed which may include a rotary mixer including a mixing chamber, a dry additive storage truck and a water storage truck. The stabilization system may also include a dry additive conduit for delivery of dry additive from the dry additive storage truck to the mixing chamber, a water conduit for delivery of water from the water storage truck to the mixing chamber, and the rotary mixer, the dry additive storage truck and the water storage truck may be rigidly connected. 
     In accordance with another aspect of the present disclosure, a method of soil stabilization of a ground surface is disclosed which may include providing a stabilization machine having a mixing chamber, a dry additive storage truck and a water storage truck; and rigidly connecting the stabilization machine, the dry additive storage truck and the water storage truck. The soil stabilization method may further include operating the stabilization machine to engage the ground surface beneath the mixing chamber and to advance forward simultaneously with the dry additive storage truck and water storage truck; mixing the ground surface with a dry additive delivered from the dry additive storage truck to the mixing chamber; and mixing the ground surface with water delivered from the water storage truck to the mixing chamber.

     While the following detailed description will be given with respect to certain illustrative embodiments, it should be understood that the drawings are not necessarily to scale and the disclosed embodiments are sometimes illustrated diagrammatically and in partial views. In addition, in certain instances, details which are not necessary for an understanding of the disclosed subject matter or which render other details too difficult to perceive may have been omitted. It should therefore be understood that this disclosure is not limited to the particular embodiments disclosed and illustrated herein, but rather to a fair reading of the entire disclosure and claims, as well as any equivalents thereto. 
     DETAILED DESCRIPTION 
     Stabilization of soil or base material pertains to the cutting and pulverizing of a base material, as well as the addition of additives and water to be mixed into the base material.  FIG. 1  illustrates an exemplary stabilization machine  100 , in this case, a rotary mixer. Although  FIG. 1  shows a rotary mixer, any other machine used in road reclamation, soil stabilization, surface pulverization or other applications is contemplated by the present disclosure. The machine  100  may include a frame  102  connected to one or more wheel or traction units  104 . Although fraction units  104  are depicted as wheels, it is to be understood that other devices, such as but not limited to tracks or the like may also be employed. According to  FIG. 1 , the machine  100  may also include an open bottom mixing chamber  106  positioned between the traction units  104 . The mixing chamber  106  may generally extend the width of the machine  100 . The mixing chamber  106  may be partially defined by a hood  108  and may include a horizontally disposed, ground engaging rotor  110  partially housed therein. An engine  112  (or other power source) may be configured to electrically, mechanically, hydraulically and/or pneumatically power the traction units  104  and the rotor  110 . 
     The rotor  110  may include components rotationally driven by the engine  112  to pulverize a base material  114  of a ground surface  116  on which the machine  100  is operating. Ground surface  116  as used herein may include any base material  114  such as soil, dirt, gravel, sand, stones, concrete, pavement and the like. The rotor  110  may further include a plurality of cutting tools  118  spaced apart and pointed in a direction of rotation (indicated by an arrow  124 ) of the rotor  110 , such that a tip end of each cutting tool  118  is driven into the base material  114  by the rotation of the rotor  110 . As the machine  100  advances along the ground surface  116  to be stabilized, the rotor  110  and cutting tools  118  penetrate the ground surface  116  and lift the base material  114  from the surface, causing the base material  114  to move upwards into the mixing chamber  106 , as indicated in  FIG. 1 . According to the present disclosure, allocations of dry additive  120  and water  122  are also introduced into the mixing chamber  106  where they collide with the upwardly moving base material  114 . In this manner, the base material  114  is cut and pulverized within the mixing chamber  106 , as well as immediately mixed with the dry additive  120  and water  122 . 
     As described above, dry additives for soil stabilization may include fly ash, lime and/or cement. The addition of water  122  into the mixing chamber  106  may aid in the mixing process by wetting the pulverized base material  114  and the dry additive  120 . Introduction of dry additives and water into the mixing chamber  106  may be through similar mechanisms. The hood  108  of the mixing chamber  106  may provide a support for systems such as spray bars, nozzles or other fixtures by which additives and water may be delivered to the mixing chamber  106  and mixed with the base material  114 . For example, spray bars supported on the hood  108  and extending the width of the mixing chamber  106  may deliver additives and water to the interior of the mixing chamber  106 . Alternatively or in addition, a series of spaced nozzles or tubes may be disposed in the hood  108  to deliver dry additives and water to the interior of the mixing chamber  106 . According to the present disclosure and illustrated in  FIG. 2 , a dry additive delivery system  130  employed to deliver dry additive to the mixing chamber  106  may be coupled to a dry additive supply line  132 . Likewise, a water delivery system  134  employed to deliver water to the mixing chamber  106  may be coupled to a water supply line  136 . Various systems  130 ,  134  for delivering dry additives and water to the mixing chamber  106 , as described above, are contemplated herein and may be spaced throughout the hood  108  of the mixing chamber  106  in any pattern that allows efficient delivery of dry additives and water across the width of the mixing chamber  106  to the subject base material  114  within the mixing chamber  106 . 
     Several factors may influence the amount of dry additive or water to be delivered to the mixing chamber  106  and mixed with the base material  114 , including: the initial characteristics of the ground surface  116  or the base material  114 , the load-bearing capacity needed, the speed at which the machine  100  advances, the speed at which the rotor  110  rotates and the depth at which the rotor  110  engages the ground surface  116 . In order to consistently control the amounts of dry additive and water delivered to the mixing chamber  106 , metering devices  138 ,  140  may be coupled with the supply lines  132 ,  136  or the delivery systems  130 ,  134 . Specifically, the dry additive delivery system  130  or the dry additive supply line  132  may have a metering device  138  that is the same as or different from a metering device  140  for the water delivery system  134  or the water supply line  136 . Alternatively, the metering devices  138 ,  140  and delivery systems  130 ,  134  may essentially be the same component, for example, a nozzle in the hood  108  of the mixing chamber  106 , the nozzle including controllable valves for metering the amounts of dry additive or water delivered to the mixing chamber  106 . 
     The metering devices  138 ,  140  for controlling the volume and rate of delivery of dry additive and/or water in the disclosed soil stabilization system may include, but are not limited to, inlets, outlets, tubes, pumps, one or more rotary feeders, pressurized components, expandable components and/or one or more valves. Additionally, the metering devices  138 ,  140  contemplated herein may be automatically computer controlled based on the forward movement of the machine  100 , on the rotation of the rotor  110  or on any other parameter such as the amount or gradation of the base material  114  estimated to exist in the mixing chamber  106  at any particular moment during operation. Alternatively, the metering devices  138 ,  140  may be controlled by an operator. 
     The disclosed stabilization system further allows for nonstop or continuous metering and delivery of dry additive and water to the base material  114  being pulverized in the mixing chamber  106  of the machine  100  during a stabilization operation. Specifically, a dry additive storage truck  146  and a water storage truck  148  may be provided for continuously supplying the stabilization machine  100  with dry additive and water. While the dry additive and water storage trucks  146 ,  148  of the present disclosure are generally self-propelled and include a cab for a driver, dry additive and water storage trucks  146 ,  148  as disclosed herein also encompass non-self-propelled apparatus, for example, a truck chassis or trailer having a dry additive or water storage container disposed thereon. As illustrated in  FIG. 2 , the dry additive supply line  132  couples the dry additive storage truck  146  to the dry additive delivery system  130 . Likewise, the water supply line  136  couples the water storage truck  148  to the water delivery system  134 . The dry additive and water supply lines  132 ,  136  may be similar or different in their construction and attachment to their respective storage trucks  146 ,  148 ; however, each functions as a conduit for delivery of dry additive or water to delivery systems  130 ,  134  and ultimately to the mixing chamber  106  of the machine  100 . The dry additive and water supply lines  132 ,  136  may include a flexible hose, tubing or any such conduit capable of extending between and transferring contents between the storage trucks  146 ,  148  and the machine  100 . 
     Water storage trucks  148  and other mobile fluid distribution systems are known in the art and may include mobile units having various combinations of actuators, pumps and valves for delivering fluid. Regarding dry additive delivery from the dry additive storage truck  146  into the dry additive supply line  132  and ultimately to the machine  100 , dry additives may be fluidized and distributed using methods similar those of fluid distribution systems. Dry additive delivery from the dry additive storage truck  146  and through supply line  132  may involve pressure manipulation through the use of air compressors, fans, suction fans or pump mechanisms. Blower/impeller systems having one or more blowers may also be employed in the presently disclosed system and methods. Ultimately, a metered amount of dry additive may be blown with a fan or compressed air system under the hood and directly into the mixing chamber  106  after passing through the metering device  138  proximate the mixing chamber  106 . As with the metering of dry additive and water into the mixing chamber  106 , delivery of the dry additive and water from the storage trucks  146 ,  148  to the supply lines  132 ,  136 , and ultimately to the mixing chamber  106 , may be automatically computer controlled or controlled by an operator such that continuous delivery at a controlled rate and volume is maintained. 
     Turning to  FIGS. 3-8 , the disclosed stabilization system may further include the attachment of the stabilization machine  100 , the dry additive storage truck  146  and water storage truck  148  to each other in a front to back manner. In this manner, the machine  100  and the storage trucks  146 ,  148  may travel or advance at the same speed and over the same ground surface  116  during the soil stabilization process. Attachment of the machine  100  and the trucks  146 ,  148  may include a rigid connection  152  (between the machine and truck frames) that is releasable, thereby detaching the machine  100  and the trucks  146 ,  148  from one another once the soil stabilization process is completed. The rigid connection  152  may be any of a number of structures known in the art for use in pulling, pushing or towing vehicles. For example, the rigid connection  152  may include a tow bar, a shank, a beam, a push/pull bar or any other rigid component that may be configured for attachment to the frames of the machine  100  and the trucks  146 ,  148 . The rigid connection  152  should be sufficiently strong and inflexible so as to support any pressure exerted thereon during the pushing or pulling of one machine  100  or truck  146 ,  148  relative to another during the stabilization process. The rigid connection  152  between the machine  100  and the trucks  146 ,  148  may also include multiple rigid connections, including multiple bars, shanks, beams and the like. 
     The frames of the machine  100  and the trucks  146 ,  148  may be adapted with any number of structures known in the art and configured to receive the rigid connection  152 , such as a hitch, hitch receiver, clamps, ball mount, coupler, chains and the like. The rigid connection  152  may be disposed at a front end or a rear end of the machine  100  and the trucks  146 ,  148 . In this manner, the interconnected machine  100  and trucks  146 ,  148  are substantially “in line” in a front to back formation with one another. This presently disclosed arrangement of the stabilization machine  100  interconnected with the dry additive storage truck  146  and the water storage truck  148  may be referred to herein as a “stabilization train.” 
       FIGS. 3-8  illustrate various possible combinations of the machine  100  and the trucks  146 ,  148  of stabilization trains in accordance with the presently disclosed stabilization system. For example, as illustrated in  FIGS. 3 and 4 , the stabilization machine  100  may be positioned between the dry additive storage truck  146  and the water storage truck  148 . Rigid connections  152  are depicted between the frame of the dry additive storage truck  146  and the stabilization machine  100 , as well as between the stabilization machine  100  and the water storage truck  148 . As described above, the storage trucks  146 ,  148  may be non-self-propelled. Therefore, due to the rigid connections  152 , the water storage truck  148  and the dry additive storage truck  146  may be either pushed or pulled by the operation and advancement of the stabilization machine  100 . Where self-propelled storage trucks  146 ,  148  are employed, the machine  100  and storage trucks  146 ,  148  advance at the same speed during the stabilization process due to the rigid connections  152  between the machine  100  and the storage trucks  146 ,  148 . 
       FIGS. 5 and 6  illustrate stabilization trains having the stabilization machine  100  positioned in front of both the water storage truck  148  and the dry additive storage truck  146 . In these exemplary stabilization trains, the rigid connections  152  may be disposed between the stabilization machine  100  and the trucks  146 ,  148 , as well as between the trucks  146 ,  148 . In operation, the stabilization trains illustrated in  FIGS. 5 and 6  may advance with the forward movement of the stabilization machine  100 . Specifically, the machine  100  may pull or tow both the water storage truck  148  and the dry additive storage truck  146 . Likewise, one or both of the storage trucks  148 ,  146  may be self-propelled. In either case, the machine  100  and the storage trucks  148 ,  146  advance forward at the same speed. 
       FIGS. 7 and 8  illustrate stabilization trains having the stabilization machine  100  positioned behind both the water storage truck  148  and the dry additive storage truck  146 . As in  FIGS. 5 and 6 , the rigid connections  152  may be disposed between the stabilization machine  100  and the trucks  146 ,  148 , as well as between the trucks  146 ,  148 . In operation, the stabilization trains illustrated in  FIGS. 7 and 8  may advance with the forward movement of the stabilization machine  100 . The machine  100  may push both the water storage truck  148  and the dry additive storage truck  146 . Likewise, one or both of the storage trucks  148 ,  146  may be self-propelled. In either case, the machine  100  and the storage trucks  148 ,  146  advance forward at the same speed. 
     While the stabilization systems illustrated in  FIGS. 3-8  include only three-member systems (stabilization machine  100 , dry additive storage truck  146  and water storage truck  148 ), stabilization systems contemplated herein may include additional members, including additional construction machines, additional storage trucks, or any additional members that may be required at a particular worksite. All such machines or members may be either self-propelled or non-self-propelled, and adapted for interconnecting through rigid connections  152  with additional machines or members. 
     In addition to the rigid connections  152  between the machine  100  and the trucks  146 ,  148  of the disclosed stabilization trains, the dry additive supply line  132  and the water supply line  136  that supply dry additive and water, respectively, to the stabilization machine  100  are also illustrated in  FIGS. 3-8 . As described above, the supply lines  132 ,  136  may be any type of conduit known in the art capable of delivering dry additive and water to the stabilization machine  100 . For example, flexible hose or tubular material like that illustrated in  FIGS. 3-8  may be employed. The supply lines  132 ,  136  may be coupled at the front or rear end of the stabilization machine  100 . For example, as illustrated in  FIG. 3 , the dry additive supply line  132  is coupled to the rear end of the machine  100 , while the water supply line  136  is couple to the front end of the machine  100 . Alternatively, in the stabilization train of  FIG. 4 , wherein the order of the trucks  146 ,  148  is reversed, the opposite configuration of the supply lines  132 ,  136  may be employed. 
     Depending on the organization of the stabilization train, both of the supply lines  132 ,  136  may be coupled at either the front or rear end of the stabilization machine  100 . For example, as illustrated in  FIGS. 5 and 6 , where the machine  100  is positioned in front of both storage trucks  146 ,  148 , both of the supply lines  132 ,  136  are coupled to the rear end of the machine  100 . Alternatively, as illustrated in  FIGS. 7 and 8 , where the machine  100  is positioned behind both storage trucks  146 ,  148 , both of the supply lines  132 ,  136  are coupled to the front end of the machine  100 . In the stabilization trains of  FIGS. 5-8 , where the machine  100  is positioned at the front or rear end of the stabilization train, a longer supply line  132 ,  136  may be required for the storage truck  146 ,  148  positioned furthest away from the machine  100 . For example, for the stabilization trains of  FIGS. 5 and 7  a dry additive supply line  132  that is long enough to extend from the dry additive storage truck  146  to the water storage truck  148  and then ultimately to the stabilization machine  100  is required. Likewise, for the stabilization trains of  FIGS. 6 and 8 , a water supply line  136  that is long enough to extend from the water storage truck  148  to the dry additive storage truck  146  and then ultimately to the stabilization machine  100  is required. Therefore, in such stabilization trains, as illustrated in  FIGS. 5-8 , the machine  100  may include at least the following coupled to either a front or rear end of the machine  100 : rigid connection  152 , dry additive supply line  132  and water supply line  136 . In any case, because the machine  100  and the trucks  146 ,  148  may be spaced apart from one another at a set length in a stabilization train (based on the length of the rigid connection  152  and the length of the trucks  146 ,  148 ), and because the machine  100  and the trucks  146 ,  148  of the stabilization train advance forward at the same speed, no manipulation of the length of the supply lines  132 ,  136  is required in the disclosed stabilization systems during the stabilization process. 
       FIG. 9  is a block diagram illustrating a method  158  for soil stabilization of a ground surface  116  according to the teachings of the present disclosure. With reference to the drawings generally, the method  158  for soil stabilization may include: a first step  160  of providing a stabilization machine  100  having a mixing chamber  106 , a dry additive storage truck  146  and a water storage truck  148 ; and a second step  162  of rigidly connecting the stabilization machine  100  to the dry additive storage truck  146  and the water storage truck  148 . Thereafter, the method  158  for soil stabilization may include the steps  166 ,  168 ,  170  of: operating the stabilization machine  100  to engage the ground surface  116  beneath the mixing chamber  106  and to travel simultaneously with the dry additive and water storage trucks  146 ,  148  over the ground surface  116  (step  166 ); mixing the ground surface  116  with dry additive delivered directly from the dry additive storage truck  146  to the mixing chamber  106  (step  167 ); and mixing the ground surface  116  with water delivered directly from the water storage truck  148  to the mixing chamber  106  (step  166 ). 
     As depicted in  FIG. 9  and detailed herein, the step  162  of rigidly connecting the stabilization machine  100 , the dry additive truck  146  and the water storage truck  148  may include rigid connections  152  between the machine  100  and trucks the  146 ,  148 . Multiple arrangements of the machine  100  and trucks the  146 ,  148  are detailed above and illustrated in  FIGS. 3-8 . The following steps  166 ,  168 ,  170 , which may or may not be simultaneously executed, may include advance movement or travel  164  of the machine  100  and the trucks  146 ,  148  together due to the rigid connections  152  there between; mixing of the ground surface  116  with dry additive may include usage of the dry additive supply line  132  between the dry additive storage truck  146  and the machine  100 ; and mixing of the ground surface  116  with water may include usage of the water supply line  136  between the water storage truck  148  and the machine  100 . This disclosed method of soil stabilization  158  may result in advance movement of the machine  100  and the trucks  146 ,  148  simultaneously at the same speed and at a fixed distance there between during a soil stabilization process. 
     While the above detailed description and drawings are made with reference to a soil stabilization system and method, it is important to note that the teachings of this disclosure can be employed on other machines and methods used in construction, agriculture and industrial environments or any other applications where stabilization machines may be employed. 
     INDUSTRIAL APPLICABILITY 
     In operation, the present disclosure can find application in any number of different industries, such as but not limited to machines for stabilizing soil prior to road construction or the like. Indeed, soil stabilization of a ground surface is oftentimes required before any road or building construction on the ground surface may proceed. The present disclosure may improve upon existing soil stabilization processes with regard to worksite dust control, dry additive loss, time loss, energy efficiency and personnel efficiency. 
     Referring to the drawings generally, a disclosed system and method for soil stabilization may include a stabilization machine  100 , a dry additive storage truck  146  and a water storage truck  148 . Similar to conventional soil stabilization systems, the presently disclosed system includes the mixing of the base material  114  with dry additive  120  and water  122 . Because of the generally light and powdery nature of dry additives such as fly ash, lime and cement, conventional means employing dry additives in soil stabilization processes generate significant amounts of dust at the worksite, resulting in undesirable working conditions for the personnel, as well as for the equipment being used. Windy conditions exacerbate these problems and may also cause significant dry additive loss. 
     The presently disclosed soil stabilization system and method may avoid excessive dust at a worksite by directly delivering dry additive to the mixing chamber  106  of a stabilization machine  100 , thereby resulting in immediate mixing of the dry additive with the subject base material  114 . In addition, the disclosed system may include the simultaneous delivery of water  122  to the mixing chamber  106 , further aiding in dust control by binding with the dry additive, as well as aiding in the mixing process by wetting the base material  114  to be stabilized. In operation, the dry additive  120  and water  122  supplied from the dry additive storage truck  146  and the water storage truck  148  are delivered directly into the mixing chamber  106  of the machine  100  via the dry additive supply line  132  and delivery system  130 , and the water supply line  136  and delivery system  134 , respectively. Within the mixing chamber  106 , the base material  114  is upwardly displaced by the rotor  110  and is simultaneously pulverized and mixed with the dry additive  120  and water  122 . In this manner, the dusty conditions associated with conventional stabilization processes are avoided. Moreover, because dry additive is delivered directly to the mixing chamber  106  and thereafter combined with the base material  114 , the unwanted loss of the dry additive is avoided. 
     The presently improved soil stabilization system and method may further include a stabilization train as described herein and depicted in  FIGS. 3-8 . Such a stabilization train may comprise an interconnected combination of the stabilization machine  100 , the dry additive storage truck  146  and the water storage truck  148 . Specifically, in addition to the supply lines  132 ,  136  between the machine  100  and the storage trucks  146 ,  148 , the stabilization train includes rigid connections  152  between the machine  100  and the storage trucks  146 ,  148 . In operation, the machine  100  and the storage trucks  146 ,  148  advance forward together, the storage trucks  146 ,  148  capable of continuously supplying dry additive and water to the mixing chamber  106  of the machine  100  during the stabilization process. As opposed to conventional stabilization systems that require refilling of built-in dry additive containers, and therefore, multiple interruptions to the stabilization process; the presently disclosed system allows for a continuous supply of a large volume of dry additive and water to the mixing chamber  106  of the stabilization machine  100  thereby eliminating any interruptions to the stabilization process. 
     The stabilization train of the present disclosure may also conserve energy in comparison to conventional stabilization processes. Specifically, due to the rigid connections  152 , forward movement of the stabilization train may be effectuated by operation of the stabilization machine  100  alone. For example, the forward movement of the stabilization machine  100  may push or pull (depending on the machine  100  placement in the train) the rigidly connected dry additive storage truck  146  and the water storage truck  148 . In this manner, the additional energy consumption associated with independently operating the dry additive storage truck  146  and water storage truck  148  is avoided. Likewise, the additional personnel and/or drivers that are required when independently operating the dry additive storage truck  146  and the water storage truck  148  may not be required in the presently disclosed stabilization processes. 
     The stabilization system and method of the present disclosure may also offer the advantages of regulated speed and fixed distances between the stabilization machine  100  and the storage trucks  146 ,  148 . Because the rigid connections  152  maintain the machine  100  and trucks  146 ,  148  in a stabilization train wherein the machine  100  and the trucks  146 ,  148  all advance together, all advance at the same speed. This configuration therefore avoids the need for any additional operator or driver for managing the speed between moving components. Moreover, the machine  100  and the trucks  146 ,  148  may be maintained at specific, fixed distances from one another in the stabilization train. In this manner, the length of the supply lines  132 ,  136  between the storage trucks  146 ,  148  and the stabilization machine  100  may also be fixed. Therefore, the presently disclosed stabilization system and methods avoid any need for manipulation of the lengths of the supply lines  132 ,  136 , as well as the energy and personnel that such manipulation may require. 
     The present disclosure thus provides an altogether new strategy for soil stabilization. While the method of mixing of dry additives and water with base material to be stabilized has previously been known and performed, prior methods have not offered the advantages of the presently disclosed system and methods. Specifically, the dusty conditions associated with the prior methods compromise the working conditions for both the personnel and the equipment at a worksite, therefore compromising the quality of the stabilization process and possibly endangering the personnel. In the context of soil stabilization, the present disclosure offers a far more efficient system and method wherein dust production may be more adequately controlled and the energy, time and personnel required may be significantly reduced.

Additionally, those skilled in the art will appreciate that various modifications might be made to the presently disclosed embodiments without departing from the full and fair scope of the present disclosure.
