Prediction of Expansion Joint Life in Concrete Pavement
Individual slabs expand as the atmosphere temperature rises. Due to the expansion of the slab, all contraction joints are integrated between the expansion joints. Following the continuous expansion of the slabs, when the allowable range of the expansion joint is exceeded, compressive forces are generated within the integrated slab. This phenomenon is known as pavement growth. Concrete pavement expansion can result in blow-ups and other pressure-related difficulties, such as buckling and crushing at transverse cracks or joints. Furthermore, these problems cause damage to adjacent structures, such as bridge abutments, decks, and access structures in the pavement. However, available theoretical solutions and methods for evaluating pavement growth and predictions of expansion joint service life are considerably limited. As a result, the pavement growth analysis model was established in this study to predict the concrete pavement expansion. This model considered factors such as pavement structure and materials, climatic conditions, expansion joint configuration, base friction characteristics, geometric imperfection, joint rotational stiffness, and design reliability. Furthermore, the pavement growth analysis model may be used to anticipate the service life of expansion joints by taking into account the elements influencing it. Various sensitivity analyses were carried out using the created model to evaluate the factors influencing the possible concrete pavement expansion. The parameters substrate type, coefficient of thermal expansion, precipitation, and alkali-silica interaction were discovered to have a substantial effect on pavement growth.
