Abstract

The invention relates to the field of road maintenance materials, in particular to tackified high-strength emulsified asphalt for surface treatment and a preparation method of the tackified high-strength emulsified asphalt. The technical key points are as follows: the paint comprises a component A and a component B, and the weight part ratio of the component A to the component B is 100: (2-10); wherein the component A is modified emulsified asphalt containing an emulsifier I; the component B is a resin emulsion containing an emulsifier II; the emulsifier I is an amine emulsifier, and the emulsifier II is an amide amphoteric emulsifier. According to the tackified high-strength emulsified asphalt for surface treatment and the preparation method thereof, the tackified high-strength emulsified asphalt for surface treatment has the characteristics of high cohesive force, good elastic recovery performance, excellent high and low temperature performance and the like, and has a remarkable improvement effect on the cohesiveness, the wear resistance, the water damage resistance and the cracking resistance of a surface treatment system mixture.

Description

technical field [0001] The invention relates to the field of road maintenance materials, in particular to a viscosified high-strength emulsified asphalt for surface treatment and a preparation method thereof. Background technique [0002] The surface treatment system refers to the road maintenance method that uses high-quality fine aggregate and polymer modified emulsified asphalt to complete the construction at one time with special construction equipment. Rainwater seeps in while improving the durability and skid resistance of road surfaces. [0003] Commonly used polymer modified emulsified asphalt is SBR emulsified asphalt and SBS modified emulsified asphalt. SBR emulsified asphalt is obtained by emulsifying road petroleum asphalt after mixing latex and soap liquid, or directly mixing latex and soap liquid with road petroleum asphalt emulsified products. SBR emulsified asphalt has low requirements for production equipment, and the production process is relatively simpl...
