摘　　要：采用软化点、针入度和延度等作为道路沥青性能的衡量指标,主要研究了废胶粉的热处理后对于改性沥青性能的影响。为此,笔者用热处理废胶粉的方法改变胶粉的某些性质,然后改变一些处理条件,与沥青进行相混。相比较沥青改性前后的三大指标,分析其改性效果。研究发现,胶粉的热处理能够一定程度地改善沥青性能。The paper studied the coating the surface of waste rubber powder for the performance of modified asphalt, and the use of softening point, penetration and ductility of asphalt roads, etc., as indicators to measure performance. To this end, author used method coating the surface of waste rubber powder to change some properties of powder, and then changed some processing conditions, and put them mixed together. Compared to the three indicators before and after the modification, then author analyzed the modification effect. The study found that pretreatment of the powder can improve the asphalt performance to a certain extent.
