• Abstract:
  The primary objective of the proposed study is to evaluate the potential benefits of incorporating wicking geotextiles (WGs) to enhance the performance of flexible pavements constructed over soft, moisture-susceptible subgrade soils in Louisiana. The study aims to investigate how WGs can enhance the capillary capacity and improve drain aggerate efficiency to transport water from the base and subgrade soil and reduce their soil moisture, mobilize reinforcement mechanisms (i.e., stabilize pavement layers), and mitigate moisture-related distresses such as rutting and fatigue. The findings will lead to the development of design guidelines and performance-based recommendations for incorporating WGs into the design of pavement systems and implementing their benefits within pavement design frameworks (e.g., AASHTOWare MEPDG).
