为了减少废轮胎污染，提高沥青混合料的性能，采用干燥法对再生轮胎橡胶改性沥青混合料的性能进行了实验室研究。对含橡胶量分别为1%、2%和3%的三种沥青混合料和不含橡胶的对照混合料进行了试验。车辙试验（60℃）、间接拉伸试验（-10℃）和方差分析结果表明，在干法沥青混合料中加入再生轮胎橡胶可以改善沥青混合料的工程性能，橡胶含量对沥青混合料的高温永久变形和低温开裂性能有显著影响。(c) 2006 Elsevier Ltd.版权所有。
To minimize waste tires pollution and improve properties of asphalt mixtures, properties of recycled tire rubber modified asphalt mixtures using dry process are studied in laboratory. Tests of three types asphalt mixtures containing different rubber content (1%, 2% and 3% by weight of total mix) and a control mixture without rubber were conducted. Based on results of rutting tests (60 degrees C), indirect tensile tests (-10 degrees C) and variance analysis, the addition of recycled tire rubber in asphalt mixtures using dry process could improve engineering properties of asphalt mixtures, and the rubber content has a significant effect on the performance of resistance to permanent deformation at high temperature and cracking at low temperature.
