Problems solved by technology

[0003] The traditional asphalt pavement treatment measures mainly include: 1. For cracks, the method of slotting and filling is mainly used, which is more convenient for construction, but the durability is poor, and cracks cannot be fundamentally solved; 2. For local subsidence caused by uneven subsidence of the roadbed , if the subgrade is already stable and does not continue to sink, it is only necessary to repair the surface layer, milling off the asphalt concrete surface to be treated first, cleaning it up, painting sticky layer oil, and subsidizing the modified asphalt concrete surface layer again, this The construction method is time-consuming and laborious, and the effect is average

Description

Technical field [0001] The invention relates to a construction method for non-excavation treatment of asphalt pavement, which is suitable for disease treatment construction of asphalt concrete pavement. Background technique [0002] Asphalt surface layer is a flexible pavement that combines mineral materials and asphalt. It has the advantages of wear resistance, slip resistance, crack resistance, and low noise. In our country, whether it is rural or urban, low-grade highway or high-grade highway, it has been widely used. However, with the ever-increasing traffic volume, the traffic load also increases. In addition to natural damage and man-made damage, a series of diseases such as cracks and deformations of varying degrees will appear over time. The appearance of these diseases not only shortens the service life of asphalt pavement, but also affects the safe and fast operation of vehicles. Timely prevention and treatment of road diseases is particularly important. It can prolon...
