Title: Analysis of Design Parameters and Mechanical Index of Pavement Structures
Abstract: Seven factors affecting the service performance of asphalt pavement on lean concrete base i.e.,thickness and modulus of surface layer,thickness and modulus of lean concrete base,thickness and modulus of cement stabilized macadam base,and modulus of roadbed,are chosen for analysis.Based on this,three typical values of each factor are chosen and the range and variance analysis of three mechanical indexes about the deflection on the surface of pavement,tensile stress at the bottom of the base layer and subbase are further carried out by orthogonal experiment method.Finally,the influencing magnitude of each factor on the mechanical indexes and the optimal combination of the factors under each mechanical index are obtained.
