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.
Claims22
A method for providing an asphalt pavement with a new wearing surface, comprising:
- spraying a rubberized asphalt emulsion onto a surface of an asphalt pavement;
- broadcasting stone into the rubberized asphalt emulsion;
- and
- irradiating the rubberized asphalt emulsion with stone and a surface layer of the asphalt pavement with radiation having a preselected peak wavelength of from 1 nm to 5 mm such that the rubberized asphalt emulsion hardens and bonds to the stone, whereby the asphalt pavement is provided with a new wearing surface wherein the preselected wavelength is selected based on at least one criterion selected from the group consisting of stone petrography of the aggregate, an asphaltene/maltene content of the asphalt emulsion and testing data conducted on representative samples.
