Addressing Flood Impact for Enhanced Resilience of Pavement Systems in Tribal Nations
Flooding represents a growing threat to the performance and longevity of pavement systems, particularly in areas with limited resources and infrastructure challenges, such as tribal nations. Pavements exposed to floods experience a range of detrimental effects, including soil erosion, reduced load-bearing capacity, increased maintenance costs, and diminished service life. This project aims to develop comprehensive strategies and tools to enhance the design and resilience of pavements subjected to frequent flooding events, especially in tribal communities. The proposed research focuses on understanding the mechanisms of flood-induced pavement damage and improving adaptation and mitigation strategies for flood-prone areas. To achieve these objectives, the project will develop a systematic process for assessing the impacts of flooding on pavement systems, along with a guideline that integrates these effects into pavement design practices using AASHTOWare Pavement ME Design (PMED). The outcomes of this research will help transportation agencies and practitioners quantify flood impacts, design resilient pavements, and incorporate these strategies into long-term planning. The research goals will be accomplished through the following tasks. Task 1: Conduct a comprehensive literature review to identify the critical factors that affect the performance of pavements exposed to flood conditions. Task 2: Identify significant factors affecting pavement resilience through data collection, stakeholder surveys, and case studies selected from tribal and adjacent regions in Oklahoma. Task 3: Investigate the impacts of moisture on material properties to study how moisture impacts roadway material properties, focusing on resilient modulus adjustments and temporal effects using data from Oklahoma Department of Transportation (ODOT) and LTPP-SMP. Task 4: Collect field performance data to analyze pavement performance data to compare flood and non-flood conditions and predict performance deterioration trends. Task 5: Perform structural analysis of flooded pavement performance to use structural simulations and moisture data to evaluate flood impacts on pavement performance and optimize traffic reopening decisions. Task 6: Develop a risk assessment framework and a pavement resilience index, which will assist inform decision-making and planning processes to enhance pavement systems' resilience to future flood events.
