Asphalt recycling vehicle
View Patent ↗A method for recycling a paved surface includes the steps of providing a motorized vehicle adapted to traverse a paved surface; providing the motorized vehicle with a plurality of degradation elements, a plurality of foaming elements and a plurality of compacting elements; each plurality being attached to a carriage slidably supported by a bearing surface of an underside of the motorized vehicle; degrading the paved surface with the plurality of degradation elements as the vehicle traverses the paved surface; foaming rejuvenation material by the plurality of foaming elements into the degraded surface as the surface is being degraded; and compacting the degraded surface and the rejuvenation material into a new surface with the plurality of compaction elements as the foaming elements continue to foam rejuvenation material into the degraded surface.
1. A method for recycling a paved surface, comprising:
providing a motorized vehicle adapted to traverse a paved surface;
providing the motorized vehicle with a plurality of degradation elements, a plurality of foaming elements and a plurality of compacting elements;
at least two of the degradation elements being adapted for independent movement relative to each other;
each plurality being attached to a carriage slidably supported by a bearing surface of an underside of the motorized vehicle;
degrading the paved surface with the plurality of degradation elements as the vehicle traverses the paved surface;
foaming rejuvenation material by the plurality of foaming elements into the degraded surface as the surface is being degraded; and
compacting the degraded surface and the rejuvenation material into a new surface with the plurality of compaction elements as the foaming elements continue to foam rejuvenation material into the degraded surface.
2. The method of claim 1 , wherein the compacting elements are tampers, rollers, and/or vibrators.
3. The method of claim 1 , wherein the compacting elements comprise a coating selected from the group consisting of Fluoropolymers, Teflon®, diamond, carbon coatings and combinations thereof.
4. The method of claim 1 , wherein the compacting elements comprise a heating element on the compacting surface.
5. The method of claim 1 , wherein at least one compacting element oscillates.
6. The method of claim 1 , wherein the frequency of oscillation of the compacting elements is controllable by a controller.
7. The method of claim 1 , wherein the compacting elements are movable with respect to the rest of the vehicle longitudinally along the axis of the vehicle or transversely normal to the axis, or combinations thereof.
8. The method of claim 1 , wherein the compacting elements comprise a density sensor.
9. The method of claim 1 , wherein the pressure applied by the compacting elements is controllable by a controller.
10. The method of claim 1 , wherein the compacting elements are independently controllable by a controller.
11. The method of claim 1 , wherein the compacting elements function as part of a closed loop system.
12. The closed loop system of claim 11 , further comprising a density sensor, a position sensor, an actuator and a controller.
13. The method of claim 1 , wherein the motorized vehicle comprises multiple rows of compactors.
14. The method of claim 1 , wherein the motorized vehicle comprises a trimming compactor.
15. The method of claim 1 , wherein the slidable carriage comprises a hydraulic actuator, a pinion gear, a smart material actuator, an electric actuator or combinations thereof.
16. The method of claim 1 , wherein the carriage is pivotable.
17. The method of claim 1 , wherein the foaming rejuvenation material comprises bitumen, tar, oil, water, resins, binding agents, waxes, synthetic clay, and combinations thereof.
18. The method of claim 1 , wherein the foaming rejuvenation material is heated to a temperature of at least 100° F.
19. The method of claim 1 , wherein the front translational elements are on old pavement and the back translational elements are on resurfaced pavement.
20. The method of claim 1 , wherein the degrading, foaming and compacting takes place between the front translational elements and the back translational elements.
