乌尔禾岩沥青改性东海基质沥青掺量研究

Analysis on the Optimal Parameter for Wuerhe Rock Asphalt to Modify the DongHai Substance Asphalt

在对乌尔禾岩沥青和东海基质沥青两种原材料性能研究的基础上,结合国内外岩沥青改性沥青的研究成果,选取5%、10%、15%、20%四种岩沥青掺配比例,进行改性沥青试验研究,通过对不同掺量下的改性沥青性能检测,对比分析试验结果,同时结合考虑经济因素,得出新疆乌尔禾岩沥青改性东海沥青的性能改善效果最明显、性能价格比最优,且低温性能不受损害的最合理掺量。

The thesis carries out the lab research of modified asphalt by selecting four parameters of rock asphalt： 5%, 10%, 15% and 20%, on the basis of the property research of those two raw materials and the achievement on the modified asphalt by rock asphalt from home and abroad. By comparing the tested re- search results on the properties of modified asphalt under different parameters and considering the economic elements, the thesis find out that the result of Xinjiang Wuerhe rock asphalt to modify the Donghai as- phalt is the most reasonable parameter and the performance cost ratio is also the best, and that the property cannot be effected under low temperature.
