USP 温拌改性沥青混合料施工技术研究

摘要

Construction technology about USP warm mix modified asphalt is studied by analyzing raw material,the mix proportion design,con-struction preparation and technology. The research indicates that:the water and dust content of USP warm mix modified asphalt should be con-trolled,the mixing time is ten seconds longer,it needs 24 h for asphalt solidification after compaction,and then secondary compacting.%从原材料选择和配合比设计、施工准备、施工工艺等环节出发，分析了USP温拌改性沥青混合料的施工技术，研究表明：USP温拌改性沥青混合料应严格控制集料含水量和粉尘含量；拌和时间延长10 s左右；压实后养生24 h，再进行二次碾压。
