Method and system for in-situ cross linking of polymers, bitumen and similar materials to increase strength, toughness and durability via irradiation with electron beams from mobile accelerators

摘要

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.

主权项

1. A system for treating and strengthening a material filling a pothole, said system comprising:
a mobile unit; at least one electron gun that emits a beam of electrons; at least one electron accelerator integrated with the mobile unit and positioned to accelerate the beam of electrons; and at least one beam extraction device comprising a scan coil that emits the accelerated beam of electrons, the at least one beam extraction device positioned on the mobile unit to irradiate the surface of and treat in-situ, the material filling the pothole, wherein irradiation of the material filling the pothole by the beam of electrons results in in-situ cross-linking of the material filling the pothole and therefore a strengthening and increased durability of the material filling the pothole.
