摘要
温拌沥青技术符合低碳公路理念,是今后路面材料的重要研究方向之一。针对Evotherm温拌沥青混合料,从体积设计角度,通过分析旋转压实密实曲线,研究压实过程中混合料的体积指标变化情况。采用密实能量指数概念评价Evotherm温拌沥青混合料的压实特性,推荐压实温度区间及合理的DAT掺量,可用于指导现场施工。
Warm-Mix Asphalt is recognized as a new pavement material of low fuel consumption,and also an important direction of research in the future.From the point of volumetric design,the compaction densification curve is used to evaluate the variation of volumetric properties of Evotherm Warm-Mix Asphalt mixture.The compaction characteristics of Evotherm Warm-Mix Asphalt mixture are discussed by densification energy index,and construction temperature and reasonable use of DAT are determined in this paper.
