STREET REPAIR PROCESS
Depending on the existing condition of the roads in your neighborhood, one or more of the following repair operations will be used. Some of the work that you may see being performed includes:
- Roadway base repair - failed sections of the roadway are cut out and replaced with new asphalt. If needed, the sub-grade, the ground below the asphalt, may also need to be replaced if we determine that it cannot properly support vehicle traffic.
- Crack sealing - cracks that form in the roadway will be sealed with a flexible sealing compound that is forced into the cracks after they are cleaned out. This helps to prevent water from infiltrating into the sub-grade - the number one cause of pavement failure and pothole formation.
- Asphalt "skin patching" - a thin "skin" of hot asphalt is applied by shovel to low areas of the roadway, after a light tar "tack coat" is sprayed in it to adhere the asphalt. The asphalt is then leveled by hand and then compacted by a machine roller. Alternatively, to cover larger patched areas to smooth them out, an asphalt paver will cover the areas with a thin layer of asphalt before it is compacted. The skin patch is not the final surface, even though it may appear, at times, to cover the whole road.
The final resurfacing will cover all of the patched areas.
