A system for working a paved surface is disclosed in one aspect of the invention as including a water deposition device for increasing the moisture content of a paved surface; a microwave generator for applying microwaves to the moisture content to heat and thereby soften the paved surface; and a degradation element for working the paved surface. In certain embodiments, the apparatus may also include a surface preparation device to fracture, puncture, mar, scrape, or scarify the paved surface prior to increasing the moisture content, and a containment device to substantially restrict the escape of water as it is deposited onto the paved surface.

What is claimed is: 1. A method for working a paved surface, the method comprising: increasing a moisture content in a paved surface by injecting pressurized water into the paved surface; heating the paved surface by applying microwaves to the moisture content and thereby softening the paved surface; and working the softened paved surface with a pavement degradation tool. 2. The method of claim 1, wherein increasing the moisture content further comprises depositing the water into at least one of cracks, holes, fissures, and voids in the paved surface. 3. The method of claim 1, further comprising at least one of fracturing, puncturing, marring, scraping, and scarifying the paved surface prior to increasing the moisture content. 4. The method of claim 1, further comprising pressurizing the water prior to increasing the moisture content. 5. The method of claim 1, further comprising heating water prior to increasing the moisture content of the paved surface. 6. The method of claim 1, wherein heating the paved surface further comprises focusing the microwaves onto a desired area of the paved surface. 7. The method of claim 1, wherein increasing the moisture content further comprises substantially restricting the escape of water as it is directed to the paved surface. 8. A system for working a paved surface, the system comprising: a water injection device for increasing the moisture content of the paved surface; a microwave generator for applying microwaves to the moisture content of the paved surface to heat and thereby soften the paved surface; and a degradation element for working the paved surface; the water injection device and microwave generator being positioned on the underside of a vehicle and the injection device being positioned before the generator. 9. The apparatus of claim 8, wherein the water injection device injects at least one of liquid water, and water vapor into the paved surface. 10. The apparatus of claim 8, wherein the water injection device injects the water into at least one of cracks, holes, fissures, and voids in the paved surface. 11. The apparatus of claim 8, further comprising a surface preparation device to at least one of fracture, puncture, mar, scrape, and scarify the paved surface prior to increasing the moisture content of the paved surface. 12. The apparatus of claim 8, further comprising a pressurization device to pressurize the water prior to increasing the moisture content of the paved surface. 13. The apparatus of claim 8, further comprising a heater to heat the water prior to increasing the moisture content of the paved surface. 14. The apparatus of claim 8, wherein the water injection device further comprises a containment device to substantially restrict the escape of water as it is injected onto the paved surface. 15. An apparatus for working a paved surface, the apparatus comprising: a vehicle to travel across a paved surface; a water injection device coupled to the vehicle, the water injection device adapted to increase the moisture content of the paved surface; a microwave generator coupled to the vehicle adjacent to and before the water injection device, the microwave generator adapted to apply microwaves to the moisture content; and a degradation element coupled to the vehicle and adapted to work the paved surface.
