Analysis of Inverted Asphalt Pavement Structure Based on Cross -Anisotropy[J]. Journal of Civil and Environmental Engineering, 2007, 29(1): 65-69. DOI: 10.11835/j.issn.1674-4764.2007.01.016.
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.
