| 摘 要： | Based on the established cross-anisotropic layered elastic theory,the effect of inverted asphalt pavement structure by granular cross-anisotropy is analyzed.The result shows that,with the decrease of granular horizontal elastic modulus,the pavement surface deflection and tensile strain at bottom of AC are increased,but the tensile stress at bottom of semi-rigid base and compressive strain at top of subgrade are decreased.The thickness of AC has significant effect on the pavement surface deflection,tensile strain at bottom of AC and compressive strain at top of subgrade,while the granular cross-anisotropy has little effect on the critical inverted pavement responses for the thicker AC.
