Warren County residents may see VDOT contractors out applying surface treatment on various secondary County roads including Route 603 (Howellsville Road) and Route 658 (Rockland Road). The application of surface treatment is a cost effective way to extend the life of the underlying pavement.  The process involves crews applying liquid asphalt sprayed directly onto the road, immediately followed by an application of small stones which are rolled and compressed into the road so they are 50-70 percent embedded in the pavement. This application is designed to extend the life of the pavement by sealing cracks in the pavement and preventing moisture damage. One of the final steps of the surface treatment process is a “blot” coat. During this step, sand or fine stone is applied to prevent any liquid asphalt from being picked up by vehicle tires, which could spray the asphalt onto a vehicle’s body. This blot coat typically stays in place for 1-3 weeks. This allows the resurfacing materials to fully cure. The surface stone or “floaters” that are on the surface of the treatment will “wear” off the surface due to traffic over a period of 7-10 days. Once this occurs the road will appear like the rest of the County’s secondary roads.  Additional information can be found on VDOT's website.
