集料级配对混合料疲劳特性的影响研究

Study on the Influence about Aggregate Grade to Asphalt Mixture Fatigue Performance

集料是混合料结构形成的决定性成分,其岩性性质、物理力学指标以及外观形状的差异,对于混合料的工作性能产生很大的影响,集料级配的不同混合料的工作性能差异很大。文中就集料级配对沥青混合料的疲劳性能的影响进行了系统试验研究,得出了相应结论。

Aggregate is the decisive composition of the mixture material structure. Its rock nature, physics mechanics index and differences of external appearance form influence the performance of asphalt mixture. It is widely different to asphalt mixture performance because of different aggregate grade. This article has carried on systematic experimental study to the impact that is about the aggregate grade to asphalt mixture fatigue performance.
