【摘要】 本论文就用废轮胎胶粉对道路沥青材料进行改性进行了文献综述，利用胶粉作为改性剂，可以改善沥青路面高温性能和低温特性。经过大量的实验证明，利用精细废胶粉改性道路石油沥青是一条较好的途径，既使沥青路面抗车辙、抗推移、低温下不易出现裂缝等能力增加，并且又可解决由于废轮胎积存而导致的污染问题。 文中主要研究的内容为改性工艺：搅拌温度、胶沥比、添加剂和搅拌时间对道路石油沥青改性以后性能的影响。经过大量的实验及数据处理，得出工艺范围。 本论文首先介绍了橡胶改性沥青的现状及沥青、胶粉的组成和结构；其次介绍了改性工艺；第三就各因素对沥青改性的影响进行了详细的分析。最后得出本文的结论。更多还原

【Abstract】 This paper summaries the new developments of study on waste rubber powder modified bitumen .Experment results testify that fine rubber powder modified bitumen is an important way to modify bitumen ,the bitumen pavement’s performances of anti-rut, anti-development and anti-crack can be improved greatly. Moreover, the pollution caused by the accumulation of waste rubber tires can be avoided because of the reuse of them.This paper studied mainly the effect of stirring temperature , stirring time .proportions of bitumen to rubber, additive and accessory ingredient on the properties of waste rubber powder modified bitumen. And then the range of technological parameters was determined by experments.This paper, at first , introduces the present situations of rubber modified bitumen ,and then the process of modifying bitumen is introduced . At last ,the effect of various factors on the modified bitumen is analyzed.更多还原
