| 摘 要： | 为研究橡胶粉细度、用量及溶胀时间对胶粉改性沥青老化性能影响.试验选用AH-70基质沥青,橡胶粉选用40目、60目和80目,进行沥青老化试验研究.试验结果表明：橡胶胶粉对沥青老化性能有较好的提升作用,但若胶粉在沥青中溶胀时间不够,对沥青改性并非胶粉越细越好.

| Abstract: | In order to study the influences on aging performance of rubber modified asphalt,the fitness,content and swelling time were considered as the influence factors. Using AH- 70 basic asphalt and rubber powder of different meshes( 40,60,80),the rubber modified asphalt was prepared and the ageing test was studied. The results show that,the rubber powder is good in increasing the aging performance of asphalt. But,if the swelling time of rubber powder in asphalt is not enough,the effect of modification of rubber powder is not depending on its fitness. |
