中文摘要：
我国废食用油已成为环境污染物，并冲击食品安全，如近年来地沟油事件频发，严重危害着人们身心健康。废食用油中含有大量不饱和脂肪酸，类似于沥青中的油分，而沥青老化后其油分会减少。根据沥青再生理论与相关研究，废食用油可作为低粘度油分用于沥青再生，有望通过以废治废的方式，实现废食用油与废旧沥青路面材料的同时利用，有利于环境保护，具有广阔的应用前景。为了实现废食用油在沥青再生领域的应用，应该重点开展废食用油的分类与处理技术、废食用油对老化沥青的再生效果、再生机理以及应用技术等方面的研究。
英文摘要：
The waste cooking oil has become one of environmental pollutants and attacks the food safety in China, especially the illegal cooking oil incidents occur frequently in recent years, which seriously endan- gers the physical and mental health of people. The waste cooking oil contains a great amount of unsaturated fat- ty acids, similar to the oil component of asphalt which will decrease due to asphalt aging. Based on the recy- cling theory and related researches of asphalt, the waste cooking oil as low viscosity oil component can be used in aged asphalt recycling, which may be expected to widely utilized and has extensive prospect. In order to a- chieve the application of waste cooking oil in asphalt recycling, we should research the classification and treat- ment technology of waste cooking oil, recycling mechanism, recycling effect and application techniques.
