ONE-DIMENSIONAL MODEL FOR ANALYSIS OF CRC PAVEMENT GROWTH
Additional Document Info
A one-dimensional model for predicting the structural response of continuously reinforced concrete (CRC) pavement due to increasing temperature and alkali-silica reaction (ASR), considering slip between concrete and reinforcing bar and friction between concrete and subbase material, is presented in this paper. The slip-stress function is modeled by a three-part linear function. The subbase friction stress function is modeled by a two-part linear function. The solution procedures of displacement functions for a semi-infinite length slab are given. The unknown coefficients in the displacement functions are determined by finding the roots of the system of nonlinear equations. A simple no-slip model is also used both for providing an initial guess and for verifying the numerical results. This model provides a more rational approximation of the structural response of CRC pavement. ASCE.
