  • Patent number: 7726905
    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.

  • Patent number: 7588388
    Abstract: In one aspect of the present invention, a paved surface reconditioning system has a vehicle adapted to traverse a paved surface. The vehicle having a press plate with a working surface having plurality of nozzles disposed therein. At least one of the nozzles has an inner diameter less than 1 mm. A fluid passage may connect the nozzle to a reservoir. The reservoir and fluid passage have a volume and a pressurizing mechanism in communication with the volume and being adapted to pressurize at least a portion of the volume.

  • Publication number: 20090052987
    Abstract: In one aspect of the invention a system for removing a layer of a paved surface comprising a vehicle is adapted to traverse a paved surface in a selected direction. The vehicle has a milling drum with an axle substantially parallel and connected to the vehicle within a milling chamber. The drum is adapted to rotate around the axle between the paved surface and the vehicle. A conveyor belt is attached to a forward end of the vehicle and comprises a portion proximate an opening of the milling chamber. The belt is adapted to carry loose aggregate from the milling drum away from the paved surface. At least one nozzle is disposed on an underside of the vehicle and is in communication with a reservoir through a pathway. The at least one nozzle is adapted to direct the loose aggregate towards the portion of the conveyor belt.

  • Patent number: 7458645
    Abstract: In one aspect of the invention, a system for removing a layer of a paved surface includes a vehicle adapted to traverse a paved surface in a selected direction. A milling drum attached to the vehicle may be adapted to rotate around an axle substantially normal the selected direction of the vehicle. A moldboard may be positioned rearward of the milling drum and also connected to the vehicle. The moldboard may comprise an end that is adapted to push aggregate removed from the paved surface in the selected direction. A plurality of nozzles may be disposed proximate the end of the moldboard which may also be in communication with a fluid reservoir through a fluid pathway.
