Test Analysis of Reinforcement Performance of Asphalt Modifier for Municipal Road Rubber
In order to improve the road performance and extend service life of municipal roads,the high temperature performance and water sta-bility of concrete reinforced with rubber asphalt modifier for road construction were analyzed in this paper.The results show that the rutting depth of asphalt mixture increases with the increase of load and temperature,and the dynamic stability of asphalt mixture decreases.The un-freezing-thawing splitting tensile strength-load strength curve of asphalt mixture presents a change law of first stabilizing,then decreasing and then stabilizing.The freeze-thaw splitting tensile strength-load strength curve shows a change law of slow decrease at first,then fast decrease,and then slow decrease.The high temperature and water stability properties of rubber powder modified asphalt are the best and decrease with the increase of the mesh number of rubber powder.
