摘　　要：对掺入LKWO-Ι型油基温拌剂前后的SBS改性沥青的软化点进行测试,并建立起一级反应老化动力学模型。求得掺入温拌剂前后的SBS改性沥青的老化动力学参数。结果表明,LKWO-Ι型油基温拌剂对SBS沥青老化过程反应活化能略有升高,在高温区对反应速率有一定的减缓作用,掺入温拌剂的沥青软化点明显降低。The softening points of two SBS modified asphalts,general SBS asphalt and SBS warm mix asphalt with LKWO-Ι oil-based warm-mixed agent were tested. A first-order reaction kinetic model of aging was established based on softening point data by calculating the kinetic parameters. The results showed that LKWO-Ι makes the activation energy of aging process slightly higher and plays a role in a high temperature region in slowing the reaction rate,asphalt under the condition of warm mixing has a more obvious decline of softening point.
