The county annually evaluates its entire road network in an effort to develop a multi-year plan for preserving and maintaining county roads in the most cost-effective way possible. This year the county will place an asphalt overlay on 12 miles and a chip seal on 97 miles of road. The county also contracts with cities to perform overlays and will resurface another 1.5 miles for Woodway.
Road Maintenance Division crews will use about 15,000 tons of asphalt to patch potholes and rough or failing pavement as well as to complete the chip sealing. Chip sealing extends the life of the road surface for an additional seven to 10 years with minimal cost. Typically crews are able to complete the work quickly to minimize impacts to residents and businesses.
The process consists of the following steps: A layer of asphalt oil is applied to the road. This is followed by a layer of crushed rock/chips. The chips are pressed into place by a roller.
The road is immediately usable, and during the following week, most remaining crushed rock is pressed into the asphalt by vehicles driving on the road. A temporary 20 m.p.h. speed limit will be enforced during that time. Crews return within a week to sweep up any remaining loose chips and replace pavement markings.
Contract overlay work has already been completed in the southeast portion of the county and will begin on June 1 in southwest Snohomish County.
Chip sealing is scheduled to begin in south and southeast Snohomish County by July 6. The county will perform work farther north by the end of July and should have all chip seal work completed by the end of August or early September.
### Work is scheduled for the following areas of Snohomish County. Schedules are weather dependent as paving activities require sufficiently warm and dry conditions.
