摘要
采用青川岩沥青和140#基质沥青,配备了不同掺量的岩沥青改性沥青。通过常规指标试验测得针入度,软化点和延度,用布氏粘度仪测得运动粘度,对原样沥青和模拟老化的沥青进行动态剪切流变仪(DSR)和弯曲梁流变仪(BBR)试验。
In this paper, modified asphalt with different contents of rock asphalt was made by Qingchuan rock asphalt and 140 # matrix asphalt. Penetration, softening point and ductility were measured by conventional index tests. The viscosity was measured by Brookfield viseometer. The dynamic shear rheological (DSR) test and bending beam rheological (BBR) test were carried out for the original asphalt and aged asphalt.
