Abstract
There is a need for non-destructive evaluation (NDE) techniques which can effectively determine the extent of damage (cracking) in concrete structures. Non-destructive, one-sided surface wave attenuation measurement is a very sensitive and practical tool for such characterization. A technique for practical determination of frequency-dependent surface wave attenuation is introduced and demonstrated to be sensitive to damage in free concrete slabs. A theoretical model for the attenuation response in undamaged free slabs is introduced and shown to accurately predict experimentally obtained responses in concrete within certain frequency limits. The theoretical model is then used to investigate the practical application of the attenuation technique to concrete pavement NDE in terms of slab depth and subbase conditions. Theoretically obtained data are presented for a variety of pavement types. Based on the presented results of the theoretical model, conclusions concerning practical application of the technique to pavement inspection are given.
