研究了四种非发泡温拌沥青(WMA)添加剂Evotherm-DAT、Sasobit、常规石蜡以及Evotherm-DAT和Sasobit复合添加剂对沥青橡胶(AR)粘结剂的流变性和化学特性的影响。本研究的主要发现包括：(1)所有选定的WMA添加剂都能有效地提高AR的工作性；(2)联合使用Evotherm-DAT和Sasobit并不是降低AR混合料施工温度的可行选择；(3)石蜡是一种潜在的AR WMA添加剂；以及(4)WMA添加剂可能会影响橡胶碎石在基质沥青中的溶解状态。(C)2016爱思唯尔有限公司。保留所有权利。
This study aims to investigate the rheological and chemical characteristics of asphalt rubber (AR) binders modified with four non-foaming warm mix asphalt (WMA) additives: Evotherm-DAT, Sasobit, conventional paraffin wax, and combined Evotherm-DAT and Sasobit. The main findings of this study include that: (1) all selected WMA additives are effective in enhancing AR's workability; (2) using combined Evotherm-DAT and Sasobit is not a viable option to reduce the construction temperature of AR mixture; (3) paraffin wax is a potential WMA additive for AR; and (4) WMA additives may affect the dissolution status of crumb rubber in base asphalt.
