摘要：
The adhesive force is one of the most important properties that affect asphalt binder's all performance in pavement. Styrene-Butadiene-Rubber (SBR) latex has been used to improve the pavement performance in low temperature for a long time. In this paper, a systematic adhesive force testing procedure based on JG/T 507-2016 and pull-off strength test was employed to investigate the interfacial interaction and adhesion strength between asphalt binder and minerals. Results indicated that different emulsifier and SBR content have a great influence on low temperature adhesion performance of SBR latex modified asphalt emulsion binders. It is noteworthy that the trends of adhesive force enhanced obviously as the value of SBR content increased, however, modified asphalt emulsion with different SBR presents different maximum value of adhesive force strength which means that an optimum proportion exist in SBR modified KLMY AH-70 asphalt binders.
