The City of College Place funds an annual Chip Seal program with REET 1 dollars to preserve the condition of city streets. “It’s not uncommon for residents to ask us why we’re chip sealing their ‘perfectly good road’ because there is ‘nothing wrong with it,’” said Public Works Director Paul Hartwig. “But that’s the point – to treat the roads early so we can keep them in good condition.” The City contracts with Walla Walla County Public Works Department to perform the work. 

Chip sealing is a process where liquid asphalt is applied to seal the road. Then, a layer of chipped rock coated with asphalt is applied to protect the seal and help improve driver traction. Once it is applied, the chip seal protects the road from becoming brittle and losing its ability to bend and flex.

By chip sealing, the county is able to extend the life of our roads in the most affordable way. Chip sealing costs about $25,000 per mile of treated road compared to a traditional 3” overlay of new asphalt that runs more than $200,000 for that same mile.

When chip seal is applied at the right time in the life cycle of pavement, it can double the lifespan of the original asphalt and extend the time between pavement overlay treatments from 15 to 30 years.
