DYNAMIC STIFFNESS ANALYSIS OF CONCRETE PAVEMENT SLABS

In this assessment of the effectiveness of the dynamic stiffness method, it was found that it is possible to obtain from a transient-dynamic-response test, a picture of the dynamic stiffness of a concrete road slab. In this study, an undeformed slab was tested with and without a void. A second slab, which had a crack across the middle was also tested with and without a void. It was found that the dynamic stiffness parameter obtained from the postprocessing of the frequency-response function is a good indicator of the integrity of the slab, in terms of the presence of cracking and the uniformity of the subgrade. Voids of varying size were readily detected with and without a crack being present. These and other study findings are discussed.
