Several Pavement Distresses Are Associated with Excess Water in the Pavement System. Hence, Controlling Subsurface Water is Crucial to Pavement's Long-Term Performance. Improving Pavement Drainage is Commonly Used to Control the Water Content in Pavement Layers. Conventional Drainage Systems Can Work under Saturated Conditions but Cannot Effectively Drain Capillary Water. a New Type of Wicking Geotextile Has Been Developed that Can Drain Water under Both Saturated and Unsaturated Conditions. in This Study, the Performance of This New Type of Geotextile in Draining Water from a Paved Road Shoulder is Evaluated. a Full-Scale Test Section Along Interstate 44 Was Constructed and Instrumented. More Than Three Years of Continuous Monitoring Proved that the Wicking Geotextile Effectively Reduced the Moisture Content of the Improved Section.
