What is claimed is: 1. A method, comprising: forming a layer of pavement aggregate by degrading pavement with a plurality of degradation elements attached to an underside of a vehicle and adapted for independent movement of each other; the degradation elements rotate about an axis substantially normal to a paved surface; providing a channel attached to the vehicle adapted to traverse an area comprising a layer of pavement aggregate, the channel being in communication with at least one supply of pavement rejuvenation material; positioning the channel so that at least a portion of the channel is disposed within the layer; and adding the pavement rejuvenation material into the layer from an opening in the channel positioned below the surface of the layer. 2. The method of claim 1, wherein the method further comprises a step of mixing at least some pavement rejuvenation material from the at least one supply with at least some pavement rejuvenation material from a second supply of pavement rejuvenation material to form a resultant rejuvenation material. 3. The method of claim 2, wherein the resultant rejuvenation material foams under atmospheric pressure. 4. The method of claim 3, wherein the step of mixing at least some of the pavement rejuvenation material from a first supply with at least some pavement rejuvenation materials of a second supply occurs under a pressure high enough to keep the resultant rejuvenation material from foaming. 5. The method of claim 3, wherein the resultant rejuvenation material foams as it exits the opening. 6. The method of claim 3, wherein the resultant rejuvenation material has characteristic of having a foaming half life of 5-60 seconds. 7. The method of claim 2, wherein the step of mixing at least some of the pavement rejuvenation material with at least some of a second supply of rejuvenation material occurs within the channel. 8. The method of claim 2, wherein the second supply of pavement rejuvenation material comprises water, a liquid, a gas, polymers, clay, wax, oil based substance, a zeolite, or combinations thereof. 9. The method of claim 8, wherein the pavement rejuvenation material from the first or second supply is heated. 10. The method of claim 1, wherein the opening of the channel is protected by a superhard material. 11. The method of claim 1, wherein the method further comprises a step of spraying the surface of the layer with pavement rejuvenation material from a sprayer attached to the vehicle. 12. The method of claim 11, wherein the sprayed pavement rejuvenation material foams under atmospheric pressure. 13. The methods of claim 1, wherein the channel is adapted to vibrate, rotate, shake, move, or oscillate. 14. The method of claim 1, wherein the pavement rejuvenation material bonds the layer of pavement aggregate to a second layer of the area. 15. The method of claim 14, wherein the channel contact the second layer. 16. The method of claim 1, wherein the layer of pavement aggregate is intended to contribute to a wearing surface, a road base, a road sub-base, a drive way, a parking lot or combinations thereof. 17. The method of claim 1, wherein the method further comprises a step of forming the layer of pavement aggregate by degrading a paved surface of the area. 18. The method of claim 1, wherein the method further comprises a step of compacting the aggregate after the pavement rejuvenation material has been added. 19. The method of claim 1, wherein a sensor is adapted to monitor a characteristic within the channel. 20. The method of claim 19, wherein the characteristic is selected from the group consisting of temperature, pressure, flow rate, density of material, volume of material, viscosity of the material, vibration or combinations thereof. 21. The method of claim 1, wherein the opening comprises a nozzle. 22. The method of claim 1, wherein the method further includes a step of heating the aggregate prior to adding the pavement rejuvenation material to 100 to 275 degrees Fahrenheit.
