摘　　要：为实现地沟油的资源化再利用,并为沥青改性技术提供新思路,解决当前日益严重的普通沥青路面病害问题,本文通过制备高性能环保型地沟油基生物油改性沥青,提出两种改性剂(聚合物改性剂和纳米改性剂)对地沟油基生物复合改性沥青的影响规律、改善效果和最佳掺量范围。结果表明两种改性剂对地沟油基生物沥青复合改性效果明显,可实现地沟油的资源化再利用,并可有效改善沥青混合料的路用性能。In order to realize the resource recycling of waste oil,provide new ideas for asphalt modification technology,and solve the current increasingly serious problems of ordinary asphalt pavement diseases,this paper prepared a high-performance and environmentally friendly waste oil-based bio-oil modified asphalt,and proposed the influence rule,improvement effect and optimum dosage range of two modifiers(polymer modifiers and nano-modifiers)on gutter oil-based bio-composite modified asphalt.The results show that the two modifiers have obvious effects on the modification of waste oil-based bio-asphalt,which can realize the resource reuse of waste oil and effectively improve the road performance of the asphalt mixture.
