Abstract

The invention discloses a polymer material for rapidly repairing asphalt pavement cracks and a preparation method of the polymer material. The repairing material is prepared from the following raw materials in parts by mass: 80 to 96 parts of matrix asphalt, 3.5 to 4.5 parts of rubber, 25 to 30 parts of polypropylene glycol, 20 to 25 parts of curing agent, 10 to 15 parts of modifier, 10 to 12 parts of dispersant, 1 to 2 parts of catalyst, 10 to 40 parts of water absorbent and 4 to 9 parts of tackifier. According to the polymer material for rapidly repairing the asphalt pavement cracks and the preparation method thereof, by adding the modifier, the swelling reaction of rubber and matrix asphalt can be effectively promoted, and light components in the asphalt can permeate in a rubber structure, so that the compatibility of the rubber and the matrix asphalt is efficiently promoted, and meanwhile, the polymer material also has relatively good high-temperature resistance; and the high-temperature self-repairing capability is also endowed, so that the tight protection of the steel bridge surface pavement structure layer on the lower-layer steel bridge panel is facilitated to a greater extent.

Description

technical field

[0001] The invention relates to the technical field of pavement crack repair materials, in particular to a polymer material for quickly repairing asphalt pavement cracks and a preparation method thereof. Background technique

[0002] At present, due to frequent use or aging problems, asphalt pavement rapidly develops minor pavement diseases, such as slightly loose repaired pavement, slightly pockmarked pavement, slight spalling of pavement fine aggregate, slight spalling of pavement coarse aggregate, early stage of pavement slag, etc. In addition, due to various reasons such as rain and snow, high temperature, and overweight trucks, cracks, cracks, and potholes will also occur on qualified roads, which will cause driving safety hazards and affect the appearance of the city;

[0003] At present, the joint filling materials used in the pavement mainly include hot asphalt, emulsified asphalt, and special materials. Among them, hot asphalt joint filling material...
