The interpretation of the measurements of surface deflections and wave velocities in the study of highway pavements

Measurements of pavement deflection profiles and wave velocities have been made at the free surfaces of some highway structures. The structures form part of a controlled experiment in highway construction, known as the Texas Transportation Institute test facility. The results have been analysed with the object of estimating significant elastic parameters (young's modulus and poisson's ratio) of the materials of which the pavements are composed. The values of the moduli obtained were used as the trial values for the computation of the velocities of surface waves at various frequencies. The results are compared with the measurements made by means of the shell vibrator.
