Washington County chip seals rural roads

Release date: 07/30/2013
Sponsored by: Department of Land Use and Transportation, Operations and Maintenance Division

Update: 08/05/13
All roads chip sealed last month (see list below) are scheduled to be swept and fog sealed by the end of this week (August 9).

Bicyclists are advised to avoid roads during and immediately after chip sealing. During the chip seal process, the road surface is covered with small, loose rock. To reduce the amount of loose rock, a polymerized (stickier) asphalt is used, a roller presses the rock into the asphalt, and the surface is swept multiple times. The process is completed with a fog seal, a fine spray of liquid asphalt and sand. The fog seal fills small voids, providing a smoother surface, turns the road color from light gray to black, and improves the performance of the chip seal. The process may take several weeks from start to completion. Your patience is appreciated.

Over half of the 1,300 miles of roads maintained by Washington County are scenic two-lane rural roads, winding through farms, forests, nurseries and vineyards. Chip sealing is a cost-effective road maintenance treatment for rural roads, preserving the road surface and extending the life of the pavement. When a road is properly maintained by chip sealing every 7 to 10 years, then much more expensive repaving is necessary only every 20 to 30 years.

Chip sealing starts in July and is completed by the end of August. The most up-to-date schedule information is posted online at www.wc-roads.com or call 503-846-ROAD (846-7623). Following is a list of the roads being chip sealed this summer (2013):
