Several roads in Pulaski County will receive seal-coating this week weather permitting

Missouri Department of Transportation crews will be making driving surface improvements on several roadways in Pulaski County this week. Starting on Wednesday, a seal coat treatment will be used to create a smoother driving surface on Route 7 between Route 133 and Route P, Route F between Loop 44 (Historic Route 66) and Parks Road, and Route P between Route 7 and Route NN. Crews will close one lane on each route between 7 a.m. and 4 p.m. each day. Flaggers and a pilot car will be in place to guide traffic through the work area.
Seal coats are a pavement repair process that is used by MoDOT on roads with lower traffic volumes to maximize available resources and extend the life of a roadway. Hot emulsion oil is sprayed onto the surface of the road, followed by finely ground rocks which are then compacted to adhere to the roadway. Excess material is swept off the surface, leaving an improved roadway that will hold up longer against the elements. The method costs about one-third of the amount of a traditional asphalt overlay. Along with a smoother driving surface for travelers, the treatment keeps water from penetrating the surface, extends the life of the roadway up to seven years, and provides improved traction.
