煤油共炼沥青砂的道路沥青性能研究

摘要

The co-refining residue of kerosene to prepare MY asphalt modified agent, the influence of MY asphalt modified agent content on the modified needle penetration, softening point and the ductility of the modified asphalt mixture stability performance were investigated.The results show that the addition of MY bituminous sand additive improves the high temperature performance and stability of asphalt, and can improve the road performance of asphalt mixture.%由煤油共炼沥青砂制备MY沥青砂改性剂,与基质沥青配混,考察MY沥青改性剂加入量对改性沥青针入度、软化点、延度及改性沥青混合料的动稳性能的影响.结果表明,MY沥青砂添加剂加入,改善了沥青的高温性能和稳定性,可以提高沥青混合料的动稳定度和水稳定性能.
