Annual Chipseal Program
Chipseal is a protective wearing surface that is placed on a street to prolong its service life. In some instances, this process is performed on pavement that is relatively new to act as a protective coating. In such cases, this process will add 5 to 7 years to the life of a street and will provide a safe, skid-resistant surface.
A thin layer of new, small rocks are spread over a fresh coat of asphalt, also referred to as oil. Approximately 7 - 10 days following the chipseal, a fogseal will be applied. Fogseal is a thinner viscosity asphalt that is applied to help set the rock, control dust and make the pavement "black" again. Once Fogseal has been applied, the roads are returned to service within one to six hours - this time span depends greatly upon weather conditions (wind, humidity, temperature, etc.) and time of day.
