| 摘 要： | 采用几种不同拌和温度制备的橡胶沥青,测试其基本性能指标及离析情况,再将剩余橡胶沥青静置存放在与其拌和温度相同的烘箱中20h,然后测定其各项指标.结果显示,随着拌和温度的升高,橡胶沥青的针入度、延度增加,离析实验软化点差变大,而软化点、黏度下降.储存后橡胶沥青的针入度、延度有所上升,而软化点、黏度会有所下降,且离析加剧....

| Abstract: | Preparation of rubber asphalt at several different mixing temperature,this paper tests their basic performance indicators and segregation situation,then put the remaining rubber asphalt in oven in the mixing temperatures for 20h,and then measure the various indicators.The results showed that,with the increasing of mixing temperature,ductility increases,the difference of softening point become larger in the segregation experiment,while the softening point,viscosity decreased.After the storage of rubber aspha... |
