摘　　要：随着近几年我国公路事业发展愈来愈快,以及部分建筑业的需求,沥青的使用量一直在上升。但沥青在高温下易流动、低温下易脆裂的特性,限制了其在工程领域中的直接使用。通过添加不同的物质对沥青进行改性是目前研究的一大重点。根据添加的改性物质的不同,现就几种主流改性沥青的发展现状进行介绍。包括掺杂橡胶改性,掺杂SBS改性、纳米粒子改性、复合改性等,探讨了各种改性机理,总结了其优缺点,并对今后的耐低温防水改性沥青研究方向进行了展望。With the rapid development of China’s highway industry in recent years and the demand of some construction industries,the use of asphalt has been increasing.However,asphalt can not be directly used in engineering because of its flowability at high temperature and easy embrittlement at low temperature.The modification of asphalt by adding different substances is a major focus of current research.According to the different modified substances added,this paper introduces the development status of several mainstream modified asphalt,including doped rubber modification,doped SBS modification,nano particle modification and composite modification,discusses various modification mechanisms,summarizes their advantages and disadvantages,and prospects the research direction of low temperature resistant and waterproof modified asphalt in the future.
