LAYER BY LAYER EVALUATION OF A PCC PAVEMENT AS IT WAS CONSTRUCTED: COMPARISON OF BACKCALCULATED VALUES TO LAB MATERIAL VALUES

This study was conducted to observe the backcalculated layer strengths of a pavement structure as each layer was constructed and compare these layer strengths to laboratory tested sample strengths. The objective was carried out by gathering Falling Weight Deflectometer deflection data on each sequential layer. The laboratory samples included bulk samples of the base, shelby tube samples of the subgrade and concrete core samples from the pavement's structure. Laboratory tests were performed on these extracted samples to estimate the resilient modulus of the subgrade and determine the modulus of elasticity of the concrete. The resilient modulus testing on the base samples was not performed because the backcalculated base results were inconclusive and no comparison could be made.
