Abstract:Alabama Highway 5 is a farm-to-market road built over an expansive clay subgrade. Moisture fluctuations cause the soil to shrink and swell, resulting in severe pavement distress. The purpose of this study was to recommend and evaluate remediation strategies that can be implemented on AL 5 and other similar roadways that are affected by swelling clays in Alabama. Specific objectives included to establish the state-of-practice for shrink swell clay remediation for highway construction and maintenance and provide a decision matrix for their use, determine the causal mechanism(s) behind shrink and swell distress on AL 5 and other selected highways in and around the Tuscaloosa area, and demonstrate the effectiveness of selected remediation strategies during resurfacing of AL 5. The state-of-practice was evaluated to examine the behavior of expansive soils and document strategies that could be used for remediation of roadways affected by these soils. Particular emphasis was placed on methods that could be implemented without removing the pavement.
