In 2008, the City of Williams, Calif., a had a problem: How to prudently spend money (from State Proposition 1B) that was earmarked for streets and roads.
A considerable portion of city streets was in poor condition due to a lack of funding for maintenance on decades-old pavement situated over clay, with free water no more than 24-36 in. below surface. This lack of adequate structure on the saturated clay had resulted in heavily cracked and deteriorated asphalt streets.
The City of Williams responded by issuing a contract for chip sealing and hot mix asphalt (HMA) overlays on fabric. Gutters were to be matched by key-cut, cold plane grinding on the HMA portion.
