JCP Behavior with Traffic and Temperature Loadings: Analysis of a Test Road in Korea

Abstract

Because traffic and environmental loadings cause concrete pavement failure, a large budget is allocated for maintenance. Through understanding the effect of traffic and temperature loadings on pavement behavior or performance, concrete pavement design can be improved. Hence, this study focuses on the behavior of jointed concrete pavement (JCP) with traffic and temperature loadings by analyzing data from a test road in Korea. Strain gauges, displacement sensors, temperature sensors, and demec gauges were used to evaluate JCP behavior. Static loading, temperature loading, and falling weight deflectometer tests were also conducted. Strain, stress, vertical movement, and joint movement were evaluated based on different slab thicknesses, measurement locations, and substructures. Overall, temperature loading was a governing factor in JCP movement. Measurement location, thickness, substructure, and depth also affect JCP behavior. In the future, the behavior of JCP will be clearer with more acquired data, which will be used in the design of Korean concrete pavement. (C) 2017 American Society of Civil Engineers.
