County Roadway Chip Seal Program

Chip Sealing will start in June or July 2021

FAQs

Chip sealing work consists of applying asphalt to a road surface followed by a layer of one-quarter inch chips that essentially create a new layer on top of the road. A week after the chips are applied, crews return to the area to apply a sealant designed to help the chips adhere to the road. Finally, the sealant is followed by roadway striping operations. See to the right to view pictures of the process.

The roads to be chip sealed have not yet been determined.

Chip sealing operations are part of the county’s primary network roadway rehabilitation plan. The process is intended to extend the lifespan of the roadway and postpone larger reconstruction efforts that would require more expensive work and longer travel restrictions. Primary network county roads are typically chip sealed every six to eight years.

Chip sealing takes place over the summer, typically in June, July, and August when weather is most favorable.
