SBS改性沥青与石料的剪切性能
Shear property of SBS modified asphalt and rock
摘要
Abstract
To solve the shortcomings of water-boiling method for evaluating the adhesion between SBS modified asphalt and aggregated rock,the adhesion evaluation method between asphalt and aggregated rock was designed based on shear test and adhesion mechanism analysis of asphalt and aggregated rock. The quantitative index was proposed to evaluate the adhesion-shear strength,and the feasibility of shear strength index was verified by shear test. The effects of SBS modifier type and dosage and test temperature on the adhesive effect of SBS modified asphalt and aggregated rock were analyzed.The results show that the adhesive effect of asphalt and aggregate is improved by SBS,and the asphalt and stone adhesion is obviously increased with the increasing of SBS dosage.Compared with matrix asphalt, the shear strength of SBS modified asphalt and stone is increased by 1 00%when SBS content is 4%.The shear strength index can be used to evaluate the adhesion of asphalt and stone quantitatively,which provides reference for performance assessment of modified asphalt and quality control.关键词
