Evaluation of Subgrade Modulus for Semi-Rigid Asphalt Pavement Using Deflection Basin Parameter
The paper presents a method based on deflection basin parameters to evaluate the subgrade modulus. The paper develops 2-D and 3-D dynamic FEM to simulate semi-rigid asphalt pavement deflection basin response under FWD loading pulse. It is discovered that the relationship between Curvature Index CI6 and Shape Factor F6 may be used to determine the subgrade modulus. The moduli, thicknesses and cracked condition of upper layers have minimal effect on the relationship between CI6 and F6. Based on the calculation and analysis, the nomograph of subgrade modulus is presented.
