摘要
Abstract
"The pre-mixed & enhanced" mixing process that means the mixture can be constructed under relatively lower temperature and show good performances at high and low temperature, resulting the best economic and environmental benefits. In this study, firstly, the natural asphalt performance improvement mechanism was studied through SEM and Fluorescence Microscope based on the micro modification mechanism. And then, Orthogonal Experiment was carried out to determine the preparation technology. Last, the performance of asphalt compound binding material with different types and percent were analyzed,the research shows that there is a stable structure of micro heterogeneous and macro evenly between natural and soft asphalt. Futhermore, the research indicated that the high temperature property and aging performance of binder are improved, while low temperature performance is reduced. To sum up, the great doses are 25% percent for TLA and Buton asphalt, besides, 8% for Qing Chuan and Albania asphalt.关键词
