Abstract

In one aspect of the invention, an apparatus for reconditioning a paved surface, has a vehicle adapted to traverse the paved surface. The vehicle has a manifold with a plurality of high pressure nozzles adapted to indent the paved surface. At least one nozzle is formed in a nozzle body with a distal end having a hard material with a hardness of at least 2,000 HK. The at least one nozzle is also in fluid communication with a fluid reservoir through a fluid pathway. The apparatus has a pressurizing mechanism and a heating mechanism for pressurizing and heating fluid in the fluid pathway.
