Abstract

A pavement repair system is provided utilizing solid phase auto regenerative cohesion and homogenization by liquid asphalt oligopolymerization technologies. The system is suitable for use in repairing asphalt pavement, including pavement exhibiting a high degree of deterioration (as manifested in the presence of potholes, cracks, ruts, or the like) as well as pavement that has been subject to previous repair and may comprise a substantial amount of dirt and other debris (e.g., chipped road paint or other damaged or disturbed surfacing materials). A system utilizing homogenization by liquid asphalt oligopolymerization is suitable for rejuvenating or repairing aged asphalt, thereby improving properties of the paving material.

First claim

What is claimed is:

1. A method for providing an elastomer coating, comprising:
applying an elastomer composition to a substrate; and
irradiating the elastomer composition with radiation having a preselected peak wavelength of from 1 nm to 5 mm, whereby the elastomer composition is cured to yield a protective and self-healing elastomer coating.

2. The method of claim 1 , wherein the elastomer composition comprises rubber.

3. The method of claim 2 , wherein the rubber is ground tire rubber.

4. The method of claim 1 , wherein a reinforcing membrane or a reinforcing fabric is applied over a top of the elastomer composition.

5. The method of claim 1 , wherein the elastomer composition is configured to act as adhesive for a reinforcing membrane or a reinforcing fabric and/or is configured to penetrate into a reinforcing membrane or a reinforcing fabric.

6. The method of claim 1 , wherein the protective elastomer coating comprises multiple layers of elastomer composition and fabric.

7. The method of claim 1 , wherein the elastomer composition is applied to the substrate in a layer of up to ⅛ inch in thickness.

8. The method of claim 1 , wherein the substrate comprises a concrete structure.

9. The method of claim 8 , wherein the concrete structure is configured for exposure to water and is selected from the group consisting of a foundation wall, a surface in a parking garage, a cistern, and a power transformer box.

10. The method of claim 1 , wherein the substrate is selected from the group consisting of a floor, a wall, a ceiling, and a support beam.

11. The method of claim 1 , wherein the applying the elastomer composition to the substrate comprises spraying the elastomer composition onto the substrate.

12. The method of claim 1 , wherein the elastomer composition comprises a water based bioresin, and wherein the substrate is a vertical or an overhead surface.

13. The method of claim 1 , wherein the substrate comprises a component of a bridge.

14. The method of claim 1 , wherein the bridge is constructed of concrete and steel.

15. The method of claim 1 , wherein the substrate comprises concrete-clad steel, and wherein the protective elastomer coating is configured to prevent attack by salts at a boundary between the cement and the steel, thereby preventing corrosion of the steel.

16. The method of claim 1 , wherein the applying the elastomer composition to the substrate comprises injecting the elastomer composition into cracks or fissures in a structure.

17. The method of claim 1 , wherein the structure is a concrete structure.

18. The method of claim 1 , wherein the substrate is a surface of a building.

19. The method of claim 1 , wherein the preselected peak wavelength is from 1,000 nm to 10,000 nm.

20. The method of claim 1 , wherein the preselected peak wavelength is from 1 nm to 10,000 nm.

21. The method of claim 20 , further comprising irradiating the elastomer composition with a second radiation having a second preselected peak wavelength of from 1 mm to 5 mm.

22. The method of claim 1 , wherein the elastomer composition is a polymer modified asphalt.

23. The method of claim 1 , wherein the radiation is generated by at least one emitter, wherein each emitter comprises an emitter panel comprising a birefringent material through which an electromagnetic radiation generated by the emitter passes, wherein the birefringent material exhibits biaxial birefringence.
