| 摘 要： | 针对橡胶沥青材料本身的特点,分析当前国内外橡胶沥青弹性恢复能力的评价指标,采用常规弹性恢复试验和自制回弹恢复试验仪,分别应用弹性恢复与回弹恢复评价不同种类、不同掺量胶粉橡胶沥青及SBS改性沥青的弹性恢复能力,研究表明回弹恢复更适宜于评价橡胶沥青的弹性恢复能力,可以更好地表征橡胶沥青在较小变形(毫米级)范围内的良好弹性性能.

| Abstract: | Aimed at the characteristic of rubber asphalt material,the index for evaluating the elasticity resuming performance of rubber asphalt currently used at home and abroad was analyzed.Based on general elasticity resuming test and self-regulating resilience tester,elasticity resuming and resilience were applied to evaluate the elasticity resuming performance of difference kinds of rubber asphalt with different rubber contents as well as SBS modified asphalt respectively.The research indicates that resilience is... |
