本文以高粘弹性沥青砂为研究对象,根据应力吸收层的受力特点,分别在不同温度(5、15、25)℃和不同加载速率(10、20、50)mm/min的条件下通过室内压缩试验、直接剪切试验、拉伸试验对其基本力学性能进行了系统研究,分析其在不同温度和加载速率下的抗压强度、劲度模7量、抗剪强度和抗拉强度。为高粘弹性沥青砂作为应力吸收层的工程应用提供理论参考。
In this paper, high viscoelastic tar sands were selected as the research objects. According to the stress characteristics of the stress-absorbing layer, they were respectively passed under different temperature (5,15,25) ℃ and different loading rates (10,20,50) mm / min Indoor compression test, direct shear test and tensile test were carried out to study its basic mechanical properties systematically. The compressive strength, the modulus of stiffness, the shear strength and the tensile strength at different temperature and loading rate were analyzed. It provides theoretical reference for engineering application of high viscoelastic asphalt sand as stress absorption layer.
