Abstract: Through the Marshall test method，the multi-target orthogonal experiment was made through the asphalt mixtures of three types of aggregates mixed of granite，basalt and limestone and three types of fillers mixed of limestone powder，heavy calciuMcarbonate powder and talcuMpowder．Based on the experiment results，by using the fuzzy mathematics method ,the influences of the combination of different aggregates and fillers on asphalt mixtures are analyzed in detail.On the bases of fuzzy element analysis and analytic hierarchy process，the fuzzy synthesis judgment on asphalt concrete guidelines is made to determine the best combination of the types of the fillers and aggregates and the best asphalt content of the mixture.

Key words: multi-targets orthogonal experiment, fuzzy element analysis, fuzzy synthesis judgment, analytic hierarchy process, best asphalt content of mixture, best combination

摘要： 使用花岗岩、玄武岩和石灰岩3种不同种类的集料和石灰石粉、重质碳酸钙和滑石粉3种不同种类的填料的沥 青混合料，利用马歇尔试验方法进行多指标正交试验的结果，运用模糊数学方法分析了不同种类的集料和不同种类 的填料对其试验结果的影响，同时利用模糊物元分析方法和层次分析法对沥青砼的马歇尔多个指标进行模糊综合 评判，从而最终确定填料与集料种类的最佳组合及其最佳油石比．
