Problems solved by technology

Using a single emulsified asphalt as the bonding material, the film has low strength, poor durability and short service life
[0007] The road maintenance materials mentioned above mostly use a single emulsified asphalt or modified emulsified asphalt as a bonding material, which is combined with sand and gravel to form a sealing layer material. The material is relatively single, and the maintenance of the road is not thorough. The sealing film has low strength and poor adhesion to the pavement base, and the pavement performance will decay in a short time

Abstract

The invention relates to an anti-skid seal coat composite material used for roads and a preparation method thereof. The composite material includes: a component A, comprising an aqueous epoxy resin emulsion and a phenol-terminated polyurethane prepolymer emulsion; a component B comprising an aqueous epoxy resin curing agent, emulsified asphalt, styrene-acrylic emulsion, a flame retardant, TiO2, color paste, ultraviolet absorber, an antioxidant, an anti-aging agent, and a defoamer; a component C including: an antiskid aggregate. The preparation method includes: uniformly blending the componentA and component B to obtain a liquid adhesion material; uniformly spraying the liquid adhesion material, according to metric use amount, on the surface of a road, and meanwhile uniformly spreading theantiskid aggregate, thereby preparing the anti-skid seal coat composite material after the liquid adhesion material is dried and cured. The composite material is based on the aqueous epoxy resin withcombination of the styrene-acrylic emulsion, polyurethane emulsion and the like, which can form a layer of compact waterproof and anti-wearing layer with the antiskid aggregate, thereby producing thecomposite material; the composite material is applied to preventive maintenance treatment on the road surface, can significantly increase the surface friction force and wearing resistance of the roadsurface, reduces water permeability coefficient, and reduces generation of diseases and safety accident.

Description

technical field [0001] The invention belongs to the technical field of road maintenance, in particular to an anti-skid sealing layer composite material used for roads and a preparation method thereof, which can effectively improve the anti-skid, waterproof and wear-resistant properties of the road surface, and is widely used in the treatment and prevention of road surface sexual maintenance. Background technique [0002] With the development of society, the traffic volume has increased significantly, and the traffic density and vehicle load have become larger and larger. How to ensure the safety, durability and rapid recovery of road functions has become a huge challenge for the road engineering industry. The development of road engineering technology is also facing a transformation from focusing on construction to paying equal attention to construction and maintenance. At present, the commonly used road maintenance methods in the world include fog seal, slurry seal and mic...
