采用薄膜烘箱老化试验(TFOT)、PAV压力老化试验,对不同剂量的AW、BLE、炭黑改性沥青进行试验,利用残留针入度比、残留粘度比、软化点增量和残留延度等老化指标来分析沥青的老化程度,与常用的沥青抗老化剂SBR进行对比,研究表明0.8%AW、0.8%BLE改性沥青抗老化性能较优,炭黑改性沥青低温性能下降较大。 Using TFOT and PAV pressure aging tests, different doses of AW, BLE and carbon black modified bitumen were tested. The effects of residual penetration ratio, residual viscosity ratio, softening point increment and residual ductility Aging index to analyze the aging degree of asphalt, compared with the commonly used asphalt anti-aging agent SBR, the research shows that 0.8% AW, 0.8% BLE modified asphalt has better aging resistance, and the low temperature performance of carbon black modified asphalt declines greatly.
