Abstract
To study road performance of dry process waste tire crumb rubber modified asphalt mixture,the paper test road performance of five types of asphalt mixtures:AM,15％WAM,10％DAM,15％DAM,and 20％DAM.The results of the main performance was as follows:15％crumb rubber can significantly improve the high temperature and low temperature properties of dry asphalt mixture,while 15％crumb rubber can improve the high temperature and low temperature properties of wet asphalt mixture to a certain extent.The high temperature and low temperature properties of the dry method modified asphalt mixture increased with the increase of the mixture amount of crumb rubber at 10％to 20％,but the water stability of the dry method modified asphalt mixture decreased with the increase of the mixture amount.关键词
