| 摘 要： | 通过3种再生剂对老化沥青进行再生实验,用针入度指数和粘温指数对再生沥青感温性进行评价并讨论再生剂的影响规律。实验结果表明,再生沥青在低温和中高温区的感温性均好于原料沥青,其中再生剂C再生的再生沥青感温性较好;3种再生剂对再生沥青中温区的感温性影响无明显规律,再生剂增加了老化沥青的感温性;再生剂A对再生沥青的高温区感温性有所降低,而再生剂B和C则略有增加。结合再生剂组分分析数据得出饱和分能降低沥青的高温区感温性,而芳香分则增加沥青的高温区感温性。

| Abstract: | Three kinds of simulation aged asphalt were recycled by three different rejuvenators. Penetration index and viscosity temperature susceptibility were used to evaluate temperature susceptibility of recycled asphalts. All of the three rejuvenators recover the aged asphalts in temperature susceptibility at low and mid-high temperature. The effect of rejuvenator C is better than others. No obvious laws are found at middle temperature,the rejuvenators increase the aged asphalts temperature susceptibilities. Reju... |
