dc.description.abstractThe numerical modelling of pavement responses is very much influenced by structural properties of pavement. The structural properties are modelled by material models. Clear understandings of pavement responses with respect to the material models are necessary to evaluate the accuracy of prediction. This paper is aimed at investigating the application of an inverse modelling technique to find the material parameters of three different models using Repeated Load Triaxial test data. The method of estimating material parameter values is based on least squares technique. Computations were performed using ABAQUS in MATLAB platform. The results of the computations are compared to each other. Numerical simulations and comparisons show a good agreement between estimated values (modulus, strain, and stress deflection) obtained using three different modelsen_US
