摘　　要：本文阐述了利用废弃塑料 (PE或PP)改性道路沥青材料和防水沥青材料的技术。分析了废弃塑料作为沥青的改性剂对沥青的软化点、脆性、针入度和延度等性能的影响。结果表明沥青的针入度和延度稍有降低 ,其软化点明显升高 ,拓宽了沥青的使用范围。This paper elaborates the technique of road pitch material and anti-water pitch material,which ultilizes useless plastics(PE or PP) to improve the properties.The effects of useless plastics as modifier to properties of softening point,brittle point are analyzed.The experimental results indicate that the penetration and ductility decrease slightly but the softening point increases signicantly and brittle temperature decreases.Thus the range of application temperature of modified pitch is extended and comprehensive properties is raised.

关 键 词：改性沥青 防水材料 铺路材料 工艺设计 针入度 软化点 延度
