摘要

By using BISAR mechanical calculation software to calculate and analyze the rubber asphalt compound pavement shear stress of different interlayer adhesive states and under the condition of stress-absorbing layer thickness, we know that the adhesive states of stress-absorbing layer, rubber asphalt surface layer, and underlying cement pavement have a direct impact on the distribution of shear stress of asphalt overlay and stress-absorbing layer, and the maximum shear stress of asphalt layer bottom will first decrease and then increase with the increase of friction parameters. Therefore, the bottom layer should have good adhesion to prevent the premature entry of shear stress growth period.
