A kind of asphalt pavement repair material

Abstract

An asphalt pavement repair material, which belongs to the field of engineering materials, the asphalt pavement repair material comprises 20-60 parts of a thermosetting polymer monomer and / or a thermosetting polymer prepolymer, 2-8 parts of an antioxidant, an accelerator 1-8 parts, admixture 10-30 parts, thermoplastic polymer 5-60 parts, initiator 10-40 parts, reinforcing agent 10-20 parts, diluent 1-60 parts, aggregate 10-40 parts. The asphalt pavement repairing material provided by the invention has the advantages of fast setting speed, repairing the pavement and restoring traffic within 30 minutes, high strength, high water density, wear resistance, simple construction and the like. The compressive strength of the pavement repaired by the asphalt pavement repair material can reach 100MPa, and the wet wheel wear value is less than 800 g m ‑2 , the amount of adhering sand to the loaded wheel is less than 450 g m in 1d of water immersion ‑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...

AI Technical Summary

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
