AC-13型沥青混合料动静态模量对比试验研究

Dynamic And Static Modulous Contrast Testing of AC-13 Asphalt Mixture

以我国沥青路面广泛采用的AC-13型沥青混合料为研究对象,对在不同温度(-20℃、-10℃、0℃、10℃、20℃)和不同频率(25 Hz、10 Hz、5 Hz、1 Hz、0.5 Hz)下的动态模量进行了测试,分析并得出了其变化规律,并与其静态模量进行比较,得到了它们之间的关系,最后给出了AC-13型沥青混合料的路用动态模量的推荐范围。

This paper selected AC-13 asphalt mixture which widely used in our country as testing object.The dynamic modulous under different temperature(-20℃、- 10℃、0℃、10℃、20℃)and frequency(25Hz、10Hz、5Hz、1Hz、0.5Hz) was measured.Its transformation law was analyzed,and compared with its static modulous to obtain their relationship.Finally the dynamic modulous used in pavement analysis was recommended.
