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.
