温拌橡胶沥青混合料路用性能研究

On Service Performance of Warm Mix Rubber Asphalt Mixture

在橡胶沥青混合料中加入温拌沥青改性剂,不仅可以有效提高橡胶沥青混合料的施工和易性和路用性能,而且能够减少能源消耗和有害气体、CO2的排放,达到节能减排的目的,符合我国发展资源节约、环境友好的绿色交通的政策要求,同时具有深远的经济和社会意义。以室内试验研究为基础,重点研究了在不同胶粉掺量下的温拌橡胶沥青混合料的路用性能,为以后实际工程作参考。

Adding warm mix asphalt modifier in rubber asphalt mixture,it not only can improve the construction workability & service performance of rubber asphalt mixture,but also can reduce energy consumption & discharge of harmful gas & CO 2 to arrive at the objectives of energy conservation & emission reduction.This technology can meet the requirements of developing green traffic(resources saving & environmentally friendly) in China,and meanwhile,can be of deep economic & social meanings.Based on indoor test researches,service performance of warm mix rubber asphalt mixture with different rubber powder mixing amount is emphasized and studied,which can provide reference for similar projects in the future.
