This year the county will chip-seal about 85 miles while paving another three miles of road with asphalt.
The county evaluates its entire road network every year to develop a multi-year plan for preserving and maintaining county roads in the most cost-effective way possible.
Chip-sealing is scheduled to begin Monday in some south county neighborhoods. The road maintenance paving crew will work from east to west in July. In August, they will work their way north and northwest. Though work progress and schedule are weather dependent, all chip-seal work should be complete by mid-September.
County road crews will use approximately 8,200 tons of asphalt to patch potholes and improve rough or failing pavement as well as to complete the chip-seal work. Chip-sealing extends the life of the road surface for an additional seven to 10 years.
The chip-seal process involves applying a layer of sticky asphalt oil to the road, then a layer of crushed rock and chips and pressing the chips in place with 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-mph speed limit will be enforced during that time. Crews will return within a week to sweep up loose rock and replace pavement striping.
Repaving work is underway and being done by Cemex.
