Abstract
A broken and seated portland cement concrete pavement (PCCP) was analyzed using destructive and nondestructive testing (NDT). The paper focuses on the results of a series of NDT methodologies by which the effective structural capacity of the overlaid pavement was estimated. The NDT included Falling Weight Deflectometer (FWD) and Road Rater (RR), followed by back-calculation and verification routines. A comparison was performed between the FWD and RR deflection bowls, which demonstrated a close correspondence between the two NDT devices. The effective modulus of the broken and seated PCCP was estimated and it showed close agreement with previous work conducted by other investigators, A large-stone hot mix asphalt (HMA) overlay was placed on top of the broken and seated PCCP; this decision was made based upon rutting resistance of this type of mix as reported in previous studies.
