Abstract
An apparatus for reconditioning a paved surface includes a vehicle adapted to traverse the paved surface. The vehicle has a manifold with a plurality of jets disposed within a surface adjacent the paved surface and at least one of the jets has a high temperature, high pressure nozzle. The high temperature, high pressure nozzle has a hard material with a hardness of at least 2,000 HK. The jets are in fluid communication with a fluid reservoir through a fluid pathway, and the fluid pathway has a pressurizing mechanism and a heating mechanism for bringing the fluid to a high temperature and a high pressure.
Claims20
An apparatus for reconditioning a paved surface, comprising:
- a vehicle adapted to traverse the paved surface;
- the vehicle comprising a manifold with a plurality of jets disposed within a surface pressed against the paved surface, at least one of the jets comprising a high temperature, high pressure nozzle;
- the high temperature, high pressure nozzle comprising a hard material with a hardness of at least 2,000 HK;
- the jets being in fluid communication with a fluid reservoir through a fluid pathway;
- and
- the fluid pathway comprising a pressurizing mechanism and a heating mechanism for bringing the fluid to a high pressure and a high temperature.
A method for reconditioning a paved surface of aggregate and asphalt cement comprising the steps of:
- providing a vehicle adapted to traverse the paved surface;
- the vehicle comprising a manifold with a plurality of jets disposed within a surface adjacent the paved surface, at least one of the jets comprising a high temperature, high pressure nozzle;
- pressurizing the paved surface by forcing the manifold against the paved surface and injecting a hot, pressurized rejuvenation material into the paved surface through the jets;
- coating a surface area of the aggregate with the rejuvenation material by suddenly depressurizing the paved surface;
- and
- compacting the depressurized paved surface.
