Title: ANALYSIS OF STRUCTURAL RESPONSE OF CONCRETE PAVEMENTS UNDER CRITICAL THERMAL-LOADING CONDITIONS
Abstract: In this paper, the results of a parametric analysis of structural response of concrete pavements under simultaneous action of traffic loads and temperature variations in the slab are given. The effects of using a bonded interface in a composite pavement slab were analyzed under the thermal-load condition. A finite element program was used to compute maximum thermal-load-induced stresses in the concrete slabs. Temperature was assumed to vary linearly along the slab depth. Results are compared with those obtained by the Westergaard equations and the influence charts of Pickett and Ray. Analysis results show that the temperature differential in the slab has significant effects on structural response of concrete pavements. The effects of these pavement parameters under critical thermal-loading conditions are also determined to be different from those under full subgrade support condition. Other findings and observations are also presented.
