Layer by Layer Evaluation of a PCC Pavement as It Was Constructed. Comparison of211 Backcalculated Values to Lab Material Values

摘要

This study was conducted to observe the background layer strengths of a pavement211u001estructure as each layer was constructed and compare these layer strengths to 211u001elaboratory tested sample strengths. The objective was carried out by gathering 211u001eFalling Weight Deflectometer deflection data on each sequential layer. The 211u001elaboratory samples included bulk samples of the base, shelby tube samples of the 211u001esubgrade, and concrete core samples from the pavement's structure. Laboratory 211u001etests were performed on these extracted samples to estimate the resilient modulus 211u001etesting on the base samples was not performed because the backcalculated base 211u001eresults were inconclusive and no comparison could be made.
