摘要
对天然岩沥青的湿法改性工艺进行了研究,按照常规性能指标、Superpave性能分级,对不同掺量下的岩沥青改性沥青进行了评价;同时利用正交实验法对剪切改性工艺进行研究,优先选出岩沥青改性沥青的最佳工艺参数设置。
Discussed the wet modification process of natural rock asphalt,and evaluated the modified asphalt under different rock asphalt according to the conventional performance index and the Superpave performance grading.While using the orthogonal experimental method to study shear modification process,and priority choose the best process parameters settings of rock asphalt modified asphalt.
