摘要 对比了不同橡胶砂掺量下橡胶砂改性沥青混凝土的力学性能,分析了其降噪机理,并对试验路段的降噪效果进行了检测.结果表明,橡胶砂改性沥青混凝土中橡胶砂的掺入对其吸声性能的改变不明显或者不存在,其降噪机理主要在于减振;橡胶砂改性沥青混凝土随橡胶砂掺量的增加,其变形等性能有一定下降.岩沥青改性沥青不仅可以提高橡胶砂改性沥青混凝土的力学性能,同时也能起到部分减振降噪作用. Mechanical performance of several crumb rubber modified asphalt concrete(CRMAC) mixtures with different use level of crumb rubber was investigated. Noise reduction mechanism of rubber modified asphalt concrete was analyzed. Also the noise reduction effect of experiment pavement was tested. It is found that the addition of crumb rubber has littile effect on sound absorption. Its main noise reduction mechanism for rubber modified asphalt concrete is damping effect. It is found that the CRMAC pavement performance such as deformation performance decreases with the increase of mixed crumb rubber amount. Rock modified asphalt has a little con- tribution to the improvement of mechanical performance, and a little contribution to vibration reduction for pavement.
