Device for Patterning Surface Coatings Applied on Pavement Surfaces

An apparatus comprising

• a vehicle capable of moving in a first direction;
• a first bar having a plurality of spray nozzles mounted thereto at defined intervals, wherein the first bar is mounted to the vehicle in a second direction that is perpendicular to the first direction;
• a second bar having a plurality of spray nozzles mounted thereto at the defined intervals, wherein the second bar is mounted to the vehicle a defined distance from the first bar in the second direction, wherein the plurality of spray nozzles on the second bar are offset from the plurality of spray nozzles on the first bar, wherein each of the plurality of spray nozzles is capable of blasting out a material at a surface coating that has been applied on a pavement surface to create grout lines in the surface coating, wherein the grout lines provide patterns in the surface coating;
• an actuator capable of moving the first bar and the second bar back and forth along the second direction;
• storage for storing the material that is to be blasted from the spray nozzles;
• a pump for pumping the material to the spray nozzles;
• and
• conduit for providing the material to the spray nozzles.
