摘要
本文利用三轴试验，通过实施“先压后拉”和“先拉后压”２种加载途径，对普通沥青混合料和丁苯橡胶沥青混合料２种材料进行了实验研究。通过分析材料的抗压强度和抗拉强度，证实了沥青混合料的运动强化特性，同时比较了这２种沥青混合料的路用性能。
his paper deals with an experimental study on mechanical behaviour of twokinds of lituminous mixtures treated rispectively with classical litumen and with polymer-bitumen. The triaxial revolution test has been applied following two types of loading pattern:traction after compression and compression after traction. By an analysis of experimental results, the kinematic hardening characteristic of bituminous mixtures has been proved, andsome differencies in the mechanical properties of the two materials have been specified.
