This paper deals with a numerical procedure to identify the acoustical parameters of road pavement from surface impedance measurements. This procedure comprises three steps. First, a suitable equivalent fluid model for the acoustical properties porous media is chosen, the variation ranges for the model parameters are set, and a sensitivity analysis for this(More)
Bearing capacity of road pavement is essential for optimum planning of road maintenance and rehabilitation. Maximum deflection is usually measured by punctual mechanical sensors at low speed (less than 10km/h) which implies safety problems and discontinuous measurements. Moreover, pavement simulations showed that parameters describing the deflection basin(More)
