To make full use of the regenerative value of waste cooking oil, and to solve the environmental pollution and food security issues caused by waste cooking oil, waste cooking oil was suggested for use in asphalt. Waste cooking oil was used to adjust the performance of virgin and aged asphalt. This review article summarizes research progress on the performance of asphalt and asphalt mixture with waste cooking oil. The results showed that a moderate dosage of waste cooking oil will improved the low-temperature performance and construction workability of petroleum asphalt and aged asphalt. The mixing and compaction temperature of asphalt mixture with waste cooking oil are reduced by up to 15 °C. The rutting resistance and fatigue resistance of modified asphalt and modified asphalt mixture with waste cooking oil are damaged. After the addition of waste cooking oil in aged asphalt, the high-temperature performance and shear rheologic property of aged asphalt will be recovered. The regeneration effect of waste cooking oil on aged asphalt and aged asphalt mixture is close to that of a traditional regeneration agent, and the partial performance of asphalt or asphalt mixture with waste cooking oil is better. There is no chemical reaction between waste cooking oil and asphalt, but the asphalt component and absorption peak intensity of partial functional groups are changed. The light components content of asphalt binder is usually increased. Further research regarding the engineering application of asphalt mixture with waste cooking oil should be conducted. The method for improving the performance of asphalt and asphalt mixture with waste cooking oil will be mainly researched.
为充分利用废弃食用油的再生价值，解决废弃食用油所造成的环境污染和食品安全问题，建议将废弃食用油用于沥青中。废弃食用油被用于调整原生沥青和老化沥青的性能。这篇综述文章总结了关于含废弃食用油的沥青及沥青混合料性能的研究进展。结果表明，适量的废弃食用油会改善石油沥青和老化沥青的低温性能及施工和易性。含废弃食用油的沥青混合料的拌和与压实温度可降低达15℃。含废弃食用油的改性沥青及改性沥青混合料的抗车辙性能和抗疲劳性能受损。在老化沥青中添加废弃食用油后，老化沥青的高温性能和剪切流变性能将得以恢复。废弃食用油对老化沥青及老化沥青混合料的再生效果与传统再生剂相近，且含废弃食用油的沥青或沥青混合料的部分性能更优。废弃食用油与沥青之间不存在化学反应，但沥青组分及部分官能团的吸收峰强度发生了变化。沥青结合料的轻质组分含量通常会增加。应针对含废弃食用油的沥青混合料的工程应用开展进一步研究。将主要研究改善含废弃食用油的沥青及沥青混合料性能的方法。
