Abstract

The invention relates to the technical field of pavement functional rapid repair, and concretely discloses a rapid permeation reinforcement repair technology for asphalt pavement surface layer degradation. The technology comprises the following steps: mixing a single-component water-based polymer, aeolian sands and a filler in a mass ratio of 100:(5-10):(1-3) to obtain a repairing material, and repairing a pavement by using the repairing material in a mechanical spraying or manual roller coating manner. As an asphalt pavement preventive maintenance technology, the technology has the advantagesof no increase of the thickness of a structural layer, no change of a pavement structure form, high construction efficiency, small influence on traffic, low comprehensive cost and wide application prospect.

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...
