随着汽车工业的快速发展,越来越多的汽车轮胎被废弃,导致废旧橡胶量急剧增多。而废旧橡胶作为一种高分子化学材料,当研磨后的橡胶粉颗粒在一定条件下加入在基质沥青中,不但大大提高了沥青的性能指标,还进而改善沥青混合料的粘结强度和弹性以及低温柔韧性,从而很好的降低了沥青路面的温度敏感性。在当今的路面材料研究中,得到了越来越多专业人士的重视。
With the rapid development of automobile industry, more and more automobile tires are abandoned, resulting in a sharp increase in the amount of scrap rubber. The waste rubber as a kind of polymer chemical materials, when the rubber powder particles after grinding under certain conditions, added to the asphalt in the base, not only greatly improve the performance of asphalt, but also to improve the bonding strength and elasticity of asphalt mixture and Low temperature flexibility, which is a good way to reduce the temperature sensitivity of asphalt pavement. In today’s pavement materials research, more and more professionals have been valued.
