| Abstract | Temperature gradient through a slab depth in jointed concrete pavement causes curling stresses. These stresses are with combination of stresses from traffic load or alone lead to pavement deterioration. Current stress analysis procedures consider the temperature gradients to be linear, though the actual vertical temperature distributions are nonlinear. The accurate prediction of these stresses can improve pavement design. The stresses also can be used for the development of performance prediction models and fatigue analysis in concrete pavement. The temperature data obtained in this study indicated that the temperature distributions within the concrete pavement slab are nonlinear. These nonlinear temperature distributions throughout the depth of pavement slab are represented well by a polynomial equation of third degree. Concrete pavement thermal stresses were determined by using Bradbury's method and new analytical method. Results show that Bradbury's method underestimated thermal stresses in concrete pavement, that linear method cannot accurately predict thermal stresses in concrete pavement. Temperature moment concept successfully used in this research for the determination of equivalent linear temperature gradient from nonlinear temperature profile. Combination of thermal stress and stress from traffic load is used for redesign (reinforcement of concrete slab). Route 10390100 in the Lampang province is selected as a case study . |
