Neighborhood Roads

These streets typically are the streets that interconnect in a neighborhood or subdivision and they may or may not have concrete or asphalt curbs along the road edges.  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.
  • HMA - Commonly referred to as blacktop, hot mix asphalt (HMA) is a form of asphalt concrete that is mixed at a contractor's hot mix plant, transported to the roadway in dump trucks, placed using a paver, and compacted with steel-wheel or rubber-tired rollers. With routine preventative maintenance, HMA yields a service life between 15-20 years.
  • Mirco Surfacing - Micro surfacing provides a thin asphalt overlay/sealer that will fill in slight imperfections and give your street a uniform color and texture.  Most importantly, it seals the pavement, thus preventing the infiltration of water, which is the most frequent cause of pavement failure.
  • Rehab - Major rehabilitation of residential roadways in older communities, to include extensive pavement rehabilitation and reconstruction, such as the associated rehabilitation of ancillary elements that may be under drains, subgrade drains, and curbs and gutters (if present). This project will not make major changes to the location or size of existing drainage structures, if any. Pavement reconstruction is the rehabilitation or replacement of the entire existing pavement structure by the placement of an equivalent or increased pavement structure. Rehabilitation usually requires the total removal and replacement of pavement exhibiting widespread areas of fatigue-related distress, base failures, subgrade failures, and locations on which otherwise aggressive pavement restoration approach is deemed impractical.
