| 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. |
