摘要
将废旧轮胎加工成粉末状,与基质沥青按照一定的比例混合搅拌制备成橡胶沥青,不仅使废旧轮胎得到了再生利用,而且可使橡胶沥青的性能得到改善。文章研究了橡胶粉粒径对沥青性能的影响,表明采用针入度评价橡胶沥青值得进一步商榷,同时胶粉细度并非越细越好。
Processing the waste tires into powder and mixing with the matrix asphalt in a certain proportion to form the rubber asphalt can not only recycle the waste tires,but also can improve the performance of rubber asphalt.This article studied the effect of rubber-powder particle size on the asphalt performance,which showed that evaluating the rubber asphalt by the penetration degree is worthy of further discussion,and it won＇t be better when the fineness of rubber powder is finer.
