旁多水利枢纽大坝心墙碾压式沥青混凝土室内配合比设计及成果分析

Laboratory Mix Design for Roller Compacted Asphalt Concrete in Dam Core of Pangduo Hydropower Project and Test Result Analysis

旁多水利枢纽大坝设计为碾压式沥青混凝土心墙砂砾石坝。沥青混凝土配合比通过室内试验提供室内沥青混凝土配合比试验成果,据以确定沥青混凝土心墙的设计参数,选择合理的沥青品种、沥青用量和矿料级配,使沥青混凝土性能满足设计要求的各项指标,为现场沥青混凝土试验及结构设计提供依据。

Pangduo Dam is designed as Sand and Gravel Dam with roller compacted asphalt concrete core.Laboratory asphalt concrete mix test results are provided to determine design parameters of asphalt concrete core and to choose proper asphalt type,content and mineral aggregate gradation so as to meet various design requirements and provide basis for site asphalt concrete test and structure design.
