Abstract

 In this study, test sections of concrete pavement were constructed on the circular accelerated pavement testing (APT) facility and subjected to 1.2 million of 49kN equivalent standard wheel loads. The test pavement has sections with and without steel mesh in concrete slab and asphalt interlayer under the slab to investigate the effect of these devices. During the loading, FWD tests were conducted periodically and the sturactural changes were evaluated with FWD backanalysis, which considered the degradation process with 3DFEM models. The analysis revealed that interior parts of the slabs did not significantly degrade, while transverse cracks exibited severe degradation. Also, it was estimated that no void formed at the transverse joint, except for two joints on the asphalt interlayer.
