Abstract

A surface preparation system, such as for surface milling, may comprise a degradation drum comprising a plurality of picks disposed on a vehicle to degrade a surface. A jet system may clean the surface with fluid after degradation. A roller comprising an absorbent material may then absorb fluid left on the surface.

Claims (23)

1. A surface preparation system, comprising:

a degradation drum comprising a plurality of picks disposed thereon to degrade a surface;

a jet system to clean the surface with fluid after degradation; and

a roller comprising an absorbent material to absorb the fluid from the surface.

2. The system of claim 1 , wherein the degradation drum and roller are disposed on a single vehicle.

3. The system of claim 1 , wherein the degradation drum and roller are disposed on separate vehicles.

4. The system of claim 3 , wherein a first vehicle comprising the roller is pulled behind a second vehicle comprising the degradation drum.

5. The system of claim 3 , wherein a vehicle comprising the roller is self propelled.

6. The system of claim 1 , wherein the absorbent material is disposed around an outer perimeter of the roller.

7. They system of claim 1 , wherein the absorbent material is elastic.

8. The system of claim 7 , wherein the absorbent material temporarily conforms to the surface.

9. The system of claim 1 , further comprising a moisture extraction system to remove absorbed fluid from the roller.

10. The system of claim 9 , wherein the moisture extraction system comprises a wringer to remove fluid by compressing at least a portion of the absorbent material.

11. The system of claim 10 , wherein the wringer comprises a cylindrical rod.

12. The system of claim 11 , wherein the cylindrical rod is rotatable around an axis.

13. The system of claim 10 , wherein the wringer comprises a fluid channel.

14. The system of claim 9 , wherein the moisture extraction system comprises a vacuum.

15. The system of claim 9 , wherein the moisture extraction system comprises a heater.

16. The system of claim 9 , further comprising a moisture collection system to gather removed fluid.

17. The system of claim 16 , wherein the moisture collection system comprises a fluid reservoir.

18. The system of claim 16 , wherein the moisture collection system comprises a pump and a filter.

19. The system of claim 16 , wherein the moisture collection system recycles fluid to the jet system.

20. The system of claim 1 , wherein the surface comprises pavement, concrete, cement, asphalt, macadam, tarmacadam or bitumen.
