It is this action which fills small cracks in the pavement when conditions warrant. A Micro-Surfacing Program involves the installation of a thin, latex modified, asphalt wearing course. The use of this product involves greater flexibility toward addressing pavement defects on streets which conventional overlays would not be cost effective at this time. This method is also beneficial on pavements which require work due to surface imperfections without causing excessive build up of additional material on the pavement cross section. This program will provide various size and depths of finish contracted patches on various asphalt streets.
Some streets have a moderate condition rating due to isolated defects on an otherwise good pavement.
They do not warrant resurfacing but can be substantially up-graded by patching the problem areas and then possibly rejuvenating and or crackfilling. Additional life expectancy and a better ride will be the result. The Heat Scarification and Overlay Program consists of a street rehabilitation process which renews asphalt streets through the process of heating, scarifying, rejuvenation and compaction of the existing asphalt surface followed by the application of a new bituminous concrete surface course. Additional work also included in this program includes the selective removal and replacement of deteriorated sections of concrete curbs and gutters, sidewalks, driveway aprons, the patching and repair of the existing road base, adjustment or reconstruction of utility frames and lids as necessary, thermoplastic pavement marking, traffic control and protection, and parkway restoration. In general, the Mill Overlay Program involves rehabilitation of streets by grinding off the top layer of pavement and relaying a new asphalt surface.
