Cover Story (view full-size image): A concrete slab mainly bears vehicle and environmental loads, and the support structure of a rigid pavement system affects its structural capacity. In this paper, a procedure to determine the optimized layer composition of a continuously reinforced concrete pavement (CRCP) is proposed using a regression analysis method. Various field tests were performed to investigate the field support characteristics, and finite element models of the support structure describing the actual field conditions were studied. A procedure for selecting the layer properties to generate the appropriate composite k-value was developed. Subsequently, multiple regression relationships between design variables of CRCP were derived. Lastly, considering the economical aspect, an algorithm for selecting the optimized layer composition of CRCP is proposed. View this paper.
