| 摘 要： | 为探究餐饮废油作为石油沥青抗老化剂的可行性,以90#基质沥青和基于餐饮废油制备的生物质重油为原材料,经高速剪切制备得到3%、5%、7%生物质重油掺量的生物沥青.基于动态剪切流变仪和弯曲梁流变仪系统地进行了老化后的基质沥青与生物沥青路用性能的对比研究.试验结果表明:随着生物质重油掺量的增加,生物沥青的中温抗疲劳性能和低温性能均有着不同程度的提高,但生物沥青的高温抗变形能力较差,与基质沥青相比更容易产生永久变形.

| Abstract: | To investigate the feasibility of bio-oil generated from waste cooking oil as anti-aging agent for the petroleum asphalt, the 90# control asphalt binder and the bio-oil produced by waste cooking oil were selected. The bio-oil modified asphalt binders were obtained according to the high speed blend tests. The road performance of the control asphalt binder and bio-oil modified asphalt binders were evaluated using the dynamic sheer rheometer and bending beam rheometer. Results show that with the increase of the bio-oil content, bio-oil modified binders present better fatigue performance and low temperature performance than the control asphalt binder, while the bio-oil modified binders show a worse rutting resistance than the control asphalt binder. |
