Abstract Use of waste bio-oil as a polymer modified asphalt (PMA) component is an effective approach to solve the related pollution problem because of tremendous consumption of asphalt binders. In this article, a bio-oil is used as softening and compatibility agent for high content SBS modified asphalt. The effect is given and is compared with that of aromatic oil. The results in this work reveal bio-oil is more advantageous to the PMA binder to exhibit better elasticity and flexibility, which are necessary to PMA. The anti-aging behaviors have also clearly been improved.

废生物油作为高含量 SBS 改性沥青的增容剂

摘要 利用废弃生物油作为聚合物改性沥青（PMA）组分是解决沥青结合料消耗量巨大的相关污染问题的有效途径。在本文中，生物油用作高含量 SBS 改性沥青的软化和相容剂。给出了效果并与芳香油的效果进行了比较。这项工作的结果表明，生物油对 PMA 粘合剂更有利，以表现出更好的弹性和柔韧性，这是 PMA 所必需的。抗衰老行为也明显得到改善。
