摘要
实验研究了添加不同SEAM和石膏晶改性剂,对道路沥青改性的影响;成功研发出一种适用于SEAM/石膏晶须复合改性沥青的制备工艺,分析了不同掺量复合改性沥青的延度、针入度、软化点的变化趋势,得到6组适合于公路沥青道路施工要求的添加物的比例。所得结果对沥青改性的制备工艺研究具有一定意义。
The effect of adding different SEAMs and gypsum crystal modifiers on asphalt has been experimentally studied.A preparation process suitable for asphalt modification using SEAM/gypsum whisker composite was developed.Then the ductility,penetration and softening trend of different dosages of modified asphalt were analyzed.Six proportions of additives suitable for asphalt road construction requirements were obtained.The results have important significance for the research on the preparation of modified asphalt system.
