Abstract:
Three different specimens of pavement were formed, which contain fiber reinforced stress absorbing layer, asphalt rubber stress absorbing layer, polymer modified asphalt emulsion adhesive layer respectively.45 ° oblique cut was employed, and pull-out test and dynamic oblique shear test method were established in order to measure the shear strength, shear bond strength and fatigue strength of the stress absorbing layer.The results show that at low temperature and with fast loading, the stress absorbing layer has higher shear strength and bond strength; asphalt rubber stress absorbing layer has more shear strength, pull strength and dynamic fatigue properties compared with the other two layers.
