Abstract

The invention provides an environment-friendly asphalt high-viscosity additive and a preparation method thereof. The environment-friendly asphalt high-viscosity additive comprises the following components in parts by mass: 100 parts of a styrene-butadiene-styrene block copolymer, 40-85 parts of a tackifying component, 10-30 parts of a compatibilizing component, 3-8 parts of a high-temperature viscosity modifier, 3-10 parts of a plasticizer, 0.3-3.0 parts of an anti-aging component and 0.2-1.0 part of an accelerant. The preparation method of the environment-friendly asphalt high-viscosity additive comprises the following steps: uniformly mixing and melting the styrene-butadiene-styrene block copolymer, the tackifying component, the compatibilizing component, the high-temperature viscosity modifier, the plasticizer, the anti-aging component and the accelerant at the temperature of 150-190 DEG C, and granulating, so as to obtain the environment-friendly asphalt high-viscosity additive. According to the present invention, the high-viscosity adhesive can be rapidly and uniformly molten and dispersed in an asphalt mixture, the mixing construction temperature of the high-viscosity adhesive in the asphalt mixture can be effectively reduced, and the used components belong to the environmental protection non-toxic material.

Description

technical field [0001] The invention relates to the field of road engineering materials, in particular to an environment-friendly asphalt high-viscosity additive and a preparation method thereof. Background technique [0002] Drainage asphalt pavement with large void characteristics has become the best pavement form to achieve a leap in the quality of road surface characteristics because of its outstanding advantages such as high anti-skid performance, low noise, suppression of water mist, prevention of water drift, and reduction of glare. However, due to the large void ratio of the drainage asphalt mixture, it is vulnerable to water damage and aging, which will lead to poor durability of the drainage asphalt pavement. Therefore, the cement must have high viscosity characteristics to make the drainage asphalt pavement have better performance. High-viscosity additives (referred to as high-viscosity agents) are one of the effective ways to improve durability. [0003] In orde...
