OVERLAY OF A BROKEN AND SEATED PCCP WITH LARGE-STONE HMA: A CASE STUDY

A broken and seated portland cement pavement (PCCP) was analyzed using destructive and nondestructive testing. The paper focuses on the results of a series of nondestructive testing (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 cracked and seated PCCP was estimated and it showed close agreement with previous work conducted by other investigators. The large-stone hot mix asphalt (HMA) overlay, which has very desirable rutting resistance properties, has shown to be a good candidate for this application.
