Excess moisture in base and subgrade soil has detrimental impacts on longevity and serviceability of pavements. Seasonal ground water level fluctuations, inundations due to storms and post-storm recess, frost penetrations and freeze-thaw effects, and uncertain climatic conditions lead to continuous moisture variation and change of stress states in pavement foundation. Reliance of current analysis and design procedures on approximate empirical approaches results in limited analysis abilities to incorporate moisture-dependency and to conduct real-time, climate-informed, forecasted pavement capacity and load restriction analyses. This paper discusses a new system dynamics framework to evaluate the pavement foundation performance by holistically incorporating pavement structure, climatic conditions, traffic loads, and moisture movement processes within a pavement system. This will include a simultaneous mechanical, hydraulic, and statistical analysis of such system in real time and potentially projecting the upcoming hydro-mechanical loading scenarios. More specifically, the framework would address the sensitivity of pavement foundation response to each contributing factor and how these factors would interact under different state conditions. In addition, results of statistical analyses could be further incorporated in load restriction decision protocols and models.
