In one aspect of the invention, a method for reconditioning a paved surface includes the steps of providing a vehicle adapted to traverse the paved surface; providing a layer of loose aggregate on an underlayer by degrading the paved surface with a degradation element attached to the vehicle; adding a foaming agent to the layer of loose aggregate on the underlayer; and coating a total aggregate surface area by mixing hot asphalt into the loose aggregate and allowing the foaming agent to expand the asphalt.

What is claimed is: 1. A method for reconditioning a paved surface; comprising: providing a vehicle adapted to traverse the paved surface; providing a layer of loose aggregate on an underlayer by degrading the paved surface with a degradation element attached to the vehicle; adding a foaming agent
What is claimed is: 1. A method for reconditioning a paved surface; comprising: providing a vehicle adapted to traverse the paved surface; providing a layer of loose aggregate on an underlayer by degrading the paved surface with a degradation element attached to the vehicle; adding a foaming agent to the layer of loose aggregate on the underlayer; and coating a total aggregate surface area by mixing hot asphalt into the loose aggregate and allowing the foaming agent to expand the asphalt. 2. The method of claim 1, wherein the foaming agent comprises azodicarbonamide inorganic carbonates, organic acids, polycarbonic acid, organic salts, inorganic oxides, zinc, potassium, water, glycerol, stearate, hydrocarbons, nucleating agents, antioxidants, pigments, fire-retardants, or combinations thereof. 3. The method of claim 1, wherein the foaming agent foams between 200 to 350 degrees Fahrenheit. 4. The method of claim 1, wherein the step of mixing at least one foaming agent with the loose aggregate occurs at a temperature below the foaming agent's decomposition threshold. 5. The method of claim 1, wherein the foaming agent has a characteristic of having a foaming half-life of 5-180 seconds. 6. The method of claim 1, wherein the method further includes a step of softening the paved surface by heating it before the step of degrading the paved surface. 7. The method of claim 1, wherein the degradation element in the step of providing a layer of loose aggregate comprises at least one vertical milling apparatus. 8. The method of claim 1, wherein the layer of pavement aggregate is consistent with incorporation into a wearing surface, a road base, a road sub-base, a drive way, a parking lot or combinations thereof. 9. The method of claim 1, wherein the method further comprises a step of compacting the aggregate while coating the total aggregate surface area. 10. The method of claim 1, wherein the method further comprises a step of fogging the pavement surface and/or loose aggregate with foaming agent using a fogger attached to the vehicle. 11. The method of claim 1, wherein hot asphalt bonds the layer of pavement aggregate to an underlayer of the paved surface. 12. The method of claim 1, wherein the method further comprises a step of mixing at least one foaming agent with at least one other component before adding the resulting mixture to the loose aggregate. 13. The method of claim 12, wherein the other component comprises material selected from the group consisting of water, liquids, gases, polymers, clays, waxes, oil based substances, zeolites, and combinations thereof. 14. The method of claim 1, wherein the foaming agent is added to the pavement and/or loose aggregate by a dispenser. 15. The method of claim 1, wherein the foaming agent is directed towards the loose aggregate by an opening of a channel attached to the vehicle that connects the opening to at least one supply of foaming agent. 16. The method of claim 14, wherein the opening of the channel is protected by a superhard material. 17. The methods of claim 14, wherein the channel is adapted to vibrate, rotate, shake, move, or oscillate. 18. The method of claim 14, wherein the opening comprises a nozzle. 19. The method of claim 14, wherein the opening in the channel is positioned below the surface of the loose aggregate while adding the foaming agent.
