| 摘 要： | 对TPS、路孚8000和Sasob it三种新型沥青添加剂的改性效果进行了系统测试和分析,考虑到常规试验和评价指标在评价改性沥青性能时存在的不足,本文利用沥青稠度测试仪和测力延度仪,并引入能表征沥青结合料高温性能的稠度指标、反映沥青低温性能的测力延度以及评判温度敏感性能的稠度—温度指数等新的评价指标,评价了添加剂对沥青的改性效果。结果表明:新指标能很好的评价改性沥青的高温、低温和温度敏感性能,路孚8000对沥青各项性能改善明显。

| Abstract: | This paper tested the effect on modified asphalt of TPS, Lufu8000 and Sasobit.In view of deficiency of familiar tests and indexes,consistency testing system and measuring-stress ductility system are used.Consistency index,measuring-stress ductility index and consistency-temperature index are utilized for appraising high-temperature performance,low-temperature performance and temperature susceptibility,respectively.Results indicated that new indexes can appraise the performances of modified asphalt effectively and Lufu8000 is a preferable additive. |
