KINGSPORT — Kingsport is getting high-tech in how it deals with the seemingly endless number of potholes on city streets.
The Kingsport Public Works Department announced last week plans to purchase a road patching vehicle that aims to repair potholes more quickly and efficiently and provide a longer-lasting patch, said Ronnie Hammonds, streets and sanitation manager for the city.
The Schwarze Road Patcher is a semi- automated spray-injected pothole patching machine that allows one worker, from inside the cab, to drive up and patch a pothole without ever leaving the vehicle.
The Board of Mayor and Aldermen approved the purchase of the vehicle during its regular meeting Tuesday night.
The cost of the truck will be $165,673, and it should be in service by the end of August.
“Potholes happen in the winter months when the asphalt plants are shut down. This will give us another option of patching those potholes in the winter months and should make the repairs a lot quicker,” Hammonds said.
The Schwarze Road Patcher cleans and dries the damaged asphalt with high-pressure air, sprays a liner of asphalt emulsion to provide a strong bond, and then injects a mixture of rock chips and emulsion under high pressure to fill the pothole from the bottom up.
