Abstract

In one aspect of the present invention a system is disclosed for removing loose aggregate from a paved surface. The system comprises a motorized vehicle that has a degradation drum connected to the underside of the vehicle. The degradation drum is enclosed by a milling chamber. The milling chamber is comprised of a plurality of plates, including a moldboard that is positioned rearward of the degradation drum. The moldboard has an end that is disposed opposite the underside. The end has a plurality of liquid jet nozzles and a blower mechanism that are directed into the milling chamber.

Claims (25)

1. A system for removing aggregate from a paved surface, comprising:

a vehicle comprising a degradation drum connected to an underside of the vehicle;

the degradation drum is enclosed by a milling chamber;

the milling chamber being defined by a plurality of plates including a moldboard positioned rearward of the degradation drum;

the moldboard comprising an end disposed opposite the underside; and

the end comprising a plurality of liquid jet nozzles and a blower mechanism that are directed into the milling chamber;

wherein the plurality of liquid jet nozzles and blower mechanism are positioned to push aggregate in a direction of travel.

2. The system of claim 1 , wherein the blower mechanism is located rearward of the plurality of liquid jet nozzles.

3. The system of claim 1 , wherein the blower mechanism expels gas that contacts the paved surface rearward of where liquid from the nozzles is configured to contact the paved surface.

4. The system of claim 1 , wherein the plurality of liquid jet nozzles are configured to eject liquid into the milling chamber.

5. The system of claim 1 , wherein the nozzles is configured to force liquid under the end of the moldboard.

6. The system of claim 1 , wherein the plurality of liquid jet nozzles is in communication with a fluid reservoir through a fluid pathway.

7. The system of claim 1 , wherein the blower mechanism is in communication with a compressor or air blower through a gas pathway.

8. The system of claim 1 , wherein the plurality of liquid jet nozzles is rigidly fixed to at least a portion of the moldboard.

9. The system of claim 1 , wherein the fluid pathway is flexibly coupled to at least a portion of the moldboard.

10. The system of claim 1 , wherein the blower mechanism is rigidly fixed to at least a portion of the moldboard.

11. The system of claim 1 , wherein the gas pathway is flexibly coupled to at least a portion of the moldboard.

12. The system of claim 1 , wherein the blower mechanism comprises an underside configured to contact the paved surface.

13. The system of claim 1 , wherein a heater is configured to heat the liquid passing through the fluid pathway.

14. The system of claim 1 , wherein the gas pathway is configured to receive exhaust from an engine of the milling machine.

15. The system of claim 1 , wherein the moldboard is curved into the milling chamber.

16. The system of claim 1 , wherein moldboard is substantially flat and slightly angled into the milling chamber.

17. The system of claim 1 , wherein the plurality of liquid jets span at least a majority of a width of the moldboard.

18. The system of claim 1 , wherein the blower mechanism spans at least a majority of a width of the moldboard.

19. The system of claim 1 , wherein the blower mechanism and the liquid jets may be formed in a unithary piece.
