Abstract

The invention discloses a material for a cold-mixing and cold-paving overlay technology and a preparation method of the material. The material comprises a cationic single-component waterborne epoxy asphalt mixture and an interface protective agent. The cationic single-component waterborne epoxy asphalt mixture and the hydrophobic organic silicon emulsion are subjected to distribution construction, and the cationic single-component water-based epoxy asphalt mixture is mixed and paved in the advancing process of a paving vehicle special for cold mixing and cold paving. After rolling and molding, hydrophobic organic silicon protection liquid is spread on the molded cationic single-component waterborne epoxy asphalt mixture by using an asphalt spreading truck. The cold-mixing and cold-paving overlay technology and material provided by the invention have the advantages of good skid resistance, low driving noise, good water sealing performance and good durability.

Description

technical field [0001] The invention relates to a road maintenance material, a preparation method and an application thereof, in particular to a material for cold-mixing and cold-paving overlay technology and a preparation method. Background technique [0002] With the increase of highway mileage and the huge increase of traffic volume, the requirements for road service quality and service life have also increased relatively. Highway construction has gradually changed from "large-scale construction" to "simultaneous construction and maintenance". Therefore, there is an imminent demand for some new pavement preventive maintenance technologies. The thin-layer overlay maintenance technology can effectively restore the flatness of the original asphalt pavement, improve the anti-skid ability, and increase the comfort and safety of driving. It is an excellent preventive maintenance technology. Thin-layer overlay maintenance technology has two methods: hot construction and cold co...
