CRACK SEALING - Cracks are filled with hot applied rubberized material to prevent water infiltration into the road base. This repair may take place one or two years in advance of scheduled resurfacing. ASPHALT PATCHING - Low areas that are imperfections in the asphalt are patched with fine asphalt concrete. Typically, these depressions are small and have settled over time. This gives the street a patchwork appearance. These repairs are done during the warmer weather sometimes a year in advance, but usually just prior to resurfacing. POTHOLE REPAIR - When water infiltrates the road surface during the winter months it will freeze and thaw. As this occurs several times, it begins to break the road surface up and creates a pothole. If the pothole is not patched, it will continue to expand in size as the process continues. Typically, potholes are filled with cold patch asphalt mix that serves as a temporary repair until the warmer months provide an opportunity to repair with hot asphalt mix. Hot asphalt mix tends to bond better than cold mix, which allows it to fill potholes better and ultimately last longer. CHIP SEAL - Application of liquid asphalt followed by placement of small rock chips on the existing pavement. This treatment adds strength to the existing pavement and can extend the life of the street by eight to ten years. ASPHALT OVERLAY - The highest form of street maintenance, overlay involves the placement of a new layer of asphalt approximately one and a half to three and a half inches thick on the street. Properly maintained, an asphalt overlay can extend the life of a street by twenty to twenty-five year although heavily used streets may require more frequent overlays.
