Integrated Full-Scale Physical Experiments and Numerical Modeling of the Performance and Rehabilitation of Highway Embankments

The resilience of transportation infrastructure, such as highway embankments, is critical to avoiding commuter delays and costly repairs. The majority of earth embankments across the United States, specifically in Region 6, are in marginal condition. The high-plasticity clays used by state departments of transportation and development (DOTDs) to construct highway embankments are subjected to many cycles of wetting and drying periods. These soils can weather, desiccate, and soften to significantly lower strengths. In addition, heavy rainfall increases the soil moisture and ultimately results in slope stability problems. As a result, highway maintenance crews continue to spend many hours fighting this problem annually. Therefore, this study aims to (1) develop a predictive tool for identifying high-risk locations that may fail so they can be made more resilient and (2) determine cost-effective methods for repairing slides. The review of past failures and continuous field monitoring will be used to develop guidelines for rehabilitating failed slopes, so that the likelihood for subsequent slides is significantly reduced.
