| 摘 要： | 以SBS为改性剂,无水三氯化铝为引发剂改性煤基沥青为路用沥青。经测定,改性后沥青的软化点增加,针入度减小。SEM表明,改性沥青比原料沥青结构均匀。IR表明,沥青与SBS发生了化学反应。

| Abstract: | Use SBS as modifier,anhydrous aluminum chloride as initiator to modify coal tar pitch for road.It was determined that the increase in softening point of modified asphalt as well as the decrease of penetration.SEM showed that the modified asphalt was more uniform than the raw bitumen structure.IR showed that a chemical reaction occurred between asphalt and SBS. |
