Analysis on Shear Stress Design Index of Long-Life Asphalt Pavement under Complex Traffic Conditions

Overloading, horizontal load effect and soft ground are the main factors that influence the formation of shear rutting of asphalt pavement. Based on the analysis on the mechanical features of Long-life asphalt pavement with flexible base, this thesis puts forward asphalt pavement’s shear stress design index under the condition of shear fatigue damage and one-off shear damage of asphalt pavement, and provides their calculating method , and gives cases analysis.
