One‐Dimensional Model for Analysis of CRC Pavement Growth

Abstract

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.
