Description

technical field [0001] The invention relates to a thermal repair process for asphalt pavement defects, in particular to an intelligent thermal repair process based on microwave heating. Background technique [0002] At present, for the daily maintenance repair of asphalt pavement, the traditional cold repair method is generally used for maintenance, that is, the old asphalt pavement after cutting is filled with a well-mixed hot asphalt mixture and then rolled and formed. This construction method has high labor intensity, low efficiency and high maintenance cost, and due to the existence of hot and cold joint problems, the service life of the repaired pavement is not long. At present, it is more popular to use far-infrared heating technology to carry out on-site thermal regeneration of asphalt pavement. However, the difficulty of on-site thermal regeneration of asphalt pavement is that the asphalt begins to soften when it is heated to more than 100 degrees Celsius. After a ce...
