Asphalt concrete pavement restoration method on basis of asphalt reclaiming agent spraying and microwave heating

The invention discloses an asphalt concrete pavement restoration method on the basis of asphalt reclaiming agent spraying and microwave heating. The method comprises the following steps: (1) spraying an asphalt reclaiming agent on an asphalt pavement to repair the asphalt concrete, wherein the asphalt reclaiming agent can fill the micro cracks in the asphalt concrete and reduce the aged asphalt; (2) heating the pavement by microwaves so as to promote the asphalt viscous flow and increase the speed of molecular diffusion, wherein during the heating process, the micro cracks in asphalt concrete can be restored through the self-healing property of asphalt concrete. When preventive maintenance or restoration needs to be performed on an asphalt pavement; a layer of asphalt reclaiming agent should be sprayed on the asphalt pavement at first, then the asphalt pavement is heated by asphalt pavement microwave heating equipment so as to carry out maintenance, and rapid restoration can be realized. Microwave heating and maintenance can also be performed before the appearance of macroscopic damages on the asphalt concrete pavement to rapidly repair the pavement. The provided restoration method is quick and efficient and barely influences the traffic.
