Chip Sealing

Chip sealing is the process of spraying emulsified asphalt on the road and dropping a layer of aggregate on the liquid asphalt then rolling over it with a rubber tire roller to set the aggregate into the asphalt. This provides a new wearing course and seals small cracks to prevent water from penetrating into the road base. $14,200 per lane mile was the average price for this treatment for projects let in 2011.
