Abstract

The invention discloses an environmentally-friendly high-viscosity modified asphalt and a preparation method thereof. The modified asphalt comprises, by mass, 55-70 parts of matrix asphalt, 3-15 partsof blend oil, 0-1 part of a plasticizer, 5-20 parts of a tackifier, 0.1-0.5 part of a stabilizer and 5-20 parts of a modifier, wherein the modifier is composed of waste tire rubber powder and SBS, and a mass ratio of the waste tire rubber powder to the SBS is (3-15):(2-10). The modified asphalt has the advantages of excellent adhesion, excellent aging resistance, low cost and simple preparation method.

Description

technical field [0001] The invention belongs to the technical field of road materials, and relates to an environment-friendly high-viscosity modified asphalt and a preparation method thereof. Background technique [0002] The porosity of permeable asphalt mixture reaches 15% to 20%, and it is easily eroded by load, water, air, and sunlight, resulting in a decrease in strength and durability, and pavement diseases. In order to improve the performance of drainage asphalt mixture, it is necessary to develop a modified asphalt binder with high bonding capacity and high stability, while satisfying the characteristics of low price, environmental protection and sustainability. [0003] The most commonly imported high-viscosity modifiers used in China are TPS modifiers from Japan and SK modifiers from South Korea. These modifiers have better performance and higher viscosity, but are expensive. For example, Japan’s TPS high-viscosity asphalt modifier is made of thermoplastic rubber...
