Abstract
A method and system for treating and strengthening material filling a pothole. One or more electron accelerators can be integrated with a mobile unit. The electron accelerators are positioned on the mobile unit to heat, irradiate and treat in-situ, both the base material and a material filling a pothole located proximate to the mobile unit, wherein irradiation of the material by the electron accelerators results in in-situ cross-linking or polymerization of the material and therefore a strengthening and increased durability of the material filling the pothole. Deep heating of the substrate allows pothole repair even under extreme low temperature winter conditions. The in-situ treatment of the material filling the pothole in a road surface to toughens and strengthens the road surface and the filled pothole which results in improved material properties of the surface, enhanced durability, and improved lifetime of the pothole fill.
