Application of Fuzzy Orthogonal Method to Asphalt Mixture Experiment

XU Dong-liang,FAN Tong-jiang,CHEN Fu-qiang,JIA Jing-peng(School of Civil Engineering & Architecture,Chongqing Jiaotong University,Chongqing 400074,China)  
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 calcium carbonate powder and talcum powder.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.
