Back calculation of pavement modulus values from surface deflection bowl data is still the best known technique for the evaluation of the structural condition of an existing pavement. Conventionally, matching the theoretical with the measured deflection bowls is performed using convergent approaches. Yet, apart from producing many solutions, back calculation may also take a reasonable long computation time. Back calculation is essentially an optimization process that could be solved using genetic algorithms, as outlined in this paper. As the results, better matching between the theoretical and the measured deflection bowls was obtained and the resulting back calculated pavement modulus values were found to be quite consistent resulting subsequently in quite similar overlay thicknesses.
