Abstract:
In order to research the relationship between composition and the fatigue performance of the semi-rigid base material, several typical semi-rigid base materials, including the skeleton-density cement stabilized aggregate, the suspend-density frame cement stabilized aggregate, the skeleton-density cement fly-ash stabilized aggregate, and the suspend-density cement fly-ash stabilized aggregate mixture, were studied by the beam specimen tensile fatigue experiment. The prediction models of different materials were obtained, and the influence of material composition on the material fatigue performance was analyzed. The results show that the skeleton-density structure mixture has better fatigue property than the suspend-density structure mixture. The cement fly-ash stabilized material has better fatigue property than the cement stabilized aggregate. The material with more cement has higher fatigue sensitivity but can bear more traffic load, the finer grade skeleton-density cement stabilized aggregate has better fatigue property. 10 tabs, 5 figs, 10 refs.
