Abstract

The invention relates to the technical field of quick repair of road surface functionality, and specifically discloses a quick penetration reinforcement repair technology for surface deterioration of asphalt pavement. The water-based polymer, aeolian sand and filler are mixed to obtain a repairing material, and the repairing material is used to repair the road surface by mechanical spraying or manual rolling. As a preventive maintenance technology for asphalt pavement, this technology does not increase the thickness of the structural layer, does not change the structural form of the pavement, has high construction efficiency, has little impact on traffic, and has low overall cost. It has broad application prospects.

Description

technical field [0001] The invention relates to the technical field of rapid functional repair of road surfaces, in particular to a rapid penetration reinforcement repair technology for surface deterioration of asphalt pavement. Background technique [0002] The asphalt pavement in the trial operation or early stage of operation may have problems such as asphalt film shedding or micro-cracks on the road surface due to insufficient pavement structural strength or overloading of passing vehicles. It develops into diseases such as pits and settlements, which greatly increases maintenance costs. [0003] The current conventional pavement repairing process includes hot patching and cold patching, but whether it is hot patching or cold patching, the material obtained by mixing asphalt or cement plus stone is used for repairing. A certain thickness will not only change the original structural form of the pavement, but also the color of asphalt and cement is not easy to mix and can...
