Asphalt pavement repair material

Abstract

The invention discloses an asphalt pavement repair material, and belongs to the field of engineering materials. The asphalt pavement repair material is prepared from 20-60 parts of monomers of thermosetting polymers and / or prepolymers of the thermosetting polymers, 2-8 parts of an antioxidant, 1-8 parts of an accelerant, 10-30 parts of an admixture, 5-60 parts of the thermosetting polymers, 10-40parts of an initiator, 10-20 parts of a reinforcing agent, 1-60 parts of a diluent and 10-40 parts of aggregates. The asphalt pavement repair material has the advantages of being high in condensationrate, strength, waterproofness and abrasion performance and capable of repairing pavement and getting the traffic to move again in 30 minutes and making construction easy. According to a pavement repaired with the asphalt pavement repair material, the compressive strength can reach 100 MPa, the wet wheel abrasion value is smaller than 800 g*m<-2>, and the load wheel adhesion sand amount water immersion 1d is smaller than 450 g*m<-2>.

Description

technical field [0001] The invention relates to the technical field of engineering materials, in particular to an asphalt pavement repair material. Background technique [0002] About 80% of the highways built in my country are asphalt pavement. Due to the rapid growth of traffic volume, large-scale vehicles, heavy loads and extreme weather conditions, the asphalt pavement has different degrees of early damage such as cracks, ruts, loose surfaces, and potholes. , reducing the performance of the pavement, and even causing damage to the pavement structure. In order to maintain the good performance of the pavement and prolong its service life, different maintenance and repair measures are required at different stages of the pavement life cycle. [0003] At present, the maintenance and repair operations of asphalt pavement are mainly divided into four categories: preventive maintenance, remedial maintenance, pavement renovation and pavement reconstruction. Preventive maintenanc...

Problems solved by technology

Among them, the hybrid overlay has the characteristics of dense and durable, anti-slip and wear-resistant, anti-fatigue, high-temperature rutting resistance and low-temperature cracking reduction, but due to the high cost, the application range is limited

And although the asphalt pavement protective coating in the prior art can alleviate the degree of hardening and embrittlement of the pavement and enhance the waterproof performance of the pavement, it cannot improve the anti-wear performance and strength of the pavement
