High-viscosity modified volcanic slag adsorption type permeable asphalt mixture
The invention belongs to the technical field of road engineering, and particularly relates to a high-viscosity modified volcanic slag adsorption type permeable asphalt mixture which comprises matrix asphalt, a high-viscosity modifier, wood fibers, coarse aggregate A, coarse aggregate B, fine aggregate C and filler D. Wherein 70 # matrix asphalt is adopted as the matrix asphalt, an RPS drainage asphalt pavement high-viscosity modifier is adopted as the high-viscosity modifier, silk type wood fibers are adopted as the wood fibers, volcanic slag is adopted as the coarse aggregate A, basalt is adopted as the coarse aggregate B, machine-made sand is adopted as the fine aggregate C, and ground volcanic ash is adopted as the filler D. The asphalt mixture provided by the invention can effectively reduce the diseases such as ruts, scattering, stripping and cracks of the traditional asphalt mixture, and improves the high temperature, water stability and adhesion performance of the asphalt mixture.
本发明属于道路工程技术领域，具体涉及一种高黏改性火山渣吸附型透水沥青混合料，其组成包括基质沥青、高黏性改性剂、木纤维、粗集料A、粗集料B、细集料C和填料D。其中，基质沥青采用70号基质沥青，高黏性改性剂采用RPS排水沥青路面高黏性改性剂，木纤维采用丝型木质纤维，粗集料A采用火山渣，粗集料B采用玄武岩，细集料C采用机制砂，填料D采用磨细火山灰。本发明的沥青混合料可有效减少传统沥青混合料的车辙、飞散、剥离、裂缝等病害，提高沥青混合料的高温、水稳定性能及黏附性能。
