摘　　要：试验研究了硅藻土改性沥青膜厚与沥青混合料路用性能的关系。通过对不同沥青膜厚沥青混合料进行马歇尔、高温车辙、低温弯曲以及冻融劈裂等一系列试验,分析了硅藻土改性沥青混合料各项路用性能与沥青膜厚度变化之间的关系,最终确定了使各项路用性能最优的硅藻土掺量。The relationship between asphalt film thickness modified by diatomite and road performance of asphalt mixture is studied by experiment.Marshall Test,rutting of high temperature,bending beam of low temperature and freeze thaw splitting of moisture stabilization are conducted to analyze the correlation between road performance of asphalt mixture modified by diatomite and the variation of asphalt film thickness.Finally,the optimum percentage of diatomite is determined basing on the best road performance.
