Computer Applications to Structural Analysis of Pavements

—Surface wave method can be used to determine the properties of the component materials of a pavement structure. The measurements are made of the differences in the phase of a wave of the Rayleigh type, received at two points at known radial spacings from the source of the wave. Pavements for highways or airport runways are usually constructed of cement concrete. Such pavements are treated as a single layer of a constant thickness overlying a semi-infinite medium. The system is dispersive and inverse methods can be employed to determine the properties of the materials of the component layers of the structure. Algebraic inverse method has been developed and employed to conduct the inversion process of the experimental dispersion curve in order to back calculate the unknown parameters of the system.
