摘要
在综述国内外排水路面及其用胶结料概况基础上,重点介绍了高粘度改性沥青的国内外使用状况,从沥青和改性剂的选择要点、性能评价和标准等方面进行了阐述。比较了直接投放式高粘度沥青改性剂和成品高粘度改性沥青的差别,展望了将来高粘度改性沥青的发展及应用趋势。
The development of porous pavements and it＇s binder used both at home and abroad were reviewed. The high viscosity modified asphalt was mainly introduced.The preparation process,properties evaluation and standard were introduced in detail.The difference between direct modification and pre - modification way was compared.In the last,the future of the modified asphalt with high viscosity was described.
