对不同天然岩沥青的湿法改性工艺进行了研究,利用正交实验法对剪切改性工艺进行研究,优选出不同岩沥青改性沥青的最佳工艺参数设置,同时结合针入度分级体系和SHAP性能分级体系对不同掺量下的岩沥青改性沥青进行了评价。
The wet modification of different natural rock asphalt was studied. The orthogonal experiment method was used to study the shear modification process, and the optimal process parameters of different rock asphalt modified asphalt were optimized. At the same time, The system and SHAP performance grading system evaluated rock asphalt modified asphalt with different content.
