This paper develops a research on the fatigue property of three normal kinds of semi-rigid base materials, on the base of the comprehensive analysis of the most up to date development of the fatigue test. It presents test results of performance for three structural types of cement stabilized macadam including suspend-dense structure framework-dense structure and framework-pore structure, for two structural types of lime fly-ash macadam including suspend-dense structure and framework-dense structure, and for cement stabilized soil. By the probability analysis of Weibull on the results of fatigue test, the paper has a serial of fatigue prefigurative models. What's more, amends these models linking to the factual pavement performance. Comparing and analyzing these fatigue models, this paper discovery the conclusion that the fatigue property of fly-ash macadam is better than that of cement stabilized macadam and cement stabilized soil. The fatigue property of framework-dense structure is better than that of suspend-dense structure. The fatigue property of framework-pore structural cement stabilized macadam is comparatively better because the bottom of the girder has formed a layer of grout in the course of forming the girder.
