The process of chip (or stone) sealing local residential roads has been a major part of the Town’s Roadway Management Program, and its wide use is the main reason that the average road condition is as high as it is given the available funding to date.
This process seals the existing road surface protecting it from weathering and water damage, and prolonging the life of the road by 8 to 12 years depending upon the previous condition of the road and the amount of traffic that the road receives.
Chip sealing a road has been found to be the most cost-effective method to maintain local neighborhood road surfaces.
The average cost to fix drainage, patch, crackfill, and chip seal a road is about $40,000 per mile of road.
Whereas, the cost of a thick asphalt overlay (2” thick) with a smooth black finish is 4 to 5 times greater than that for chip sealing.
