Pavement repair system
First Claim
1. A method for providing a road with a wearing surface, comprising:
- providing a paving material comprising an asphalt binder and an aggregate;
irradiating the paving material with radiation having a preselected peak wavelength of from 1,000 nm to 10,000 nm, wherein the peak wavelength of the radiation is selected based on at least one criterion selected from the group consisting of absorbed wavelength quanta data related to a stone petrography of the aggregate, an asphaltene/maltene content of the asphalt binder, and data from testing conducted on representative samples of the paving material; and
applying the irradiated paving material to a road base, whereby the road base is provided with a wearing surface.

Abstract
A pavement repair system 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.
