摘　　要：为了研究沥青膜厚度对混合料性能的影响并确定其最佳厚度,通过室内试验分析了不同沥青膜厚度的混合料力学性能,试验结果表明:当沥青膜厚度为9~10μm时,混合料的综合性能最优,混合料设计时,推荐沥青膜厚度取9~10μm,温度较高地区取下限9μm,寒冷地区取上限10μm。In order to study the influence of asphalt film thickness on mixture properties and determine its best thickness,the analysis on mechanical properties of mixtures with different asphalt film thickness is made through laboratory test. The test results show that： when the asphalt film thickness is 9 ~ 10μm,the combination property of mixture is the best. When performing the design on the mixture,it is recommended that take 9 ~ 10μm for asphalt film thickness,take lower limit 9μm in region with higher temperature,and take upper limit 10μm in cold region.
