First Claim
1. A method for providing an asphalt pavement with a new wearing surface, comprising:
- transferring a road plating composition to a surface of an asphalt pavement, the road plating composition comprising a binder and graded stone; and
irradiating the road plating composition and a surface layer of the asphalt pavement with a radiation having a preselected peak wavelength of from 1 nm to 10000 nm, whereby the asphalt pavement is provided with a new wearing surface comprising the irradiated road plating composition atop the irradiated surface layer of the asphalt pavement, wherein the peak wavelength of the radiation is selected such that the radiation penetrates through and heats the road plating composition and the surface layer of the asphalt pavement to a depth of at least two inches from a topmost pavement surface, wherein a temperature differential throughout a top two inches of the pavement is 100°
F. or less, wherein a highest temperature in the top two inches of the pavement does not exceed 300°
F., and wherein a minimum temperature in the top two inches of the pavement is at least 200°

Abstract
A pavement repair system utilizes 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.
