Oregon Department of Transportation maintenance crews from Warrenton and Humbug will chip seal a 2-mile section of U.S. Highway 103 (Fish Hawk Highway) from Milepost 0 to Milepost 2 today and Tuesday, from 7 a.m. until 6 p.m. Flaggers and pilot cars will control traffic through the project.
A chip seal is an oil and rock mixture placed on top of aging pavements to prolong service life. Chip sealing is a highway preservation technique in which the surface of the road is first covered with a layer of hot, thick oil. The oil is then covered with a layer of gravel using a specialized piece of equipment called a chip spreader. The spreader consists of a hopper and a wide conveyor belt that spreads an even layer of gravel on the road. The gravel is then pressed into the oil with a motorized roller.
