摘要
良好的高温抗车辙性和抗疲劳性是评价沥青及沥青混合料路用性能的关键因素。探讨了动态剪切流变仪(DSR)对沥青高温稳定性和抗疲劳性能的测定方法,对抗车辙指标及抗疲劳指标进行了系统的阐述。简述了基于动态剪切流变仪(DSR)沥青高温抗车辙性能及抗疲劳性能方面的研究。文献资料显示:动态剪切流变仪(DSR)方法非常适合对沥青的高温抗车辙性能和抗疲劳性能的测试,配合其他仪器能够更好的测试沥青的性能。
Good high temperature rutting resistance and fatigue resistance are the key factors to evaluate the road performance of asphalt and asphalt mixture. The dynamic shear rheometer（DSR） was used to measure the high temperature stability and anti-fatigue performance of asphalt. The rutting index and anti-fatigue index were systematically expounded. The research on anti-rutting performance and anti-fatigue performance of asphalt based on Dynamic Shear Rheometer（DSR） was briefly described. The literature showed that dynamic shear rheometer（DSR） was a very suitable method to test the high temperature rutting resistance and fatigue resistance of asphalt and can be used to better test the performance of asphalt with other instruments.
