Abstract:
In order to estimate the ability of resistance to permanent deformation for asphalt treated base mixtures, this paper analyzes the force model for triaxial tests and simplifies it. By using unconfined compressive strength test and splitting strength test, it studies the mechanics performance and antishearing strength parameters of asphalt treated base mixtures. The results show that internal friction angle will increase with increase of nominal maximum size or content of coarse aggregate, but cohesive force will reduce. Enhancing the viscosity of binder can improve the cohesive force obviously, but it has little effect on the internal friction angle. So antishearing strength parameters based on unconfined compressive strength test and splitting test, can be used for estimating design of the antishearing performance of asphalt treated base mixtures. 2 tabs, 7 figs, 9 refs.
