Evaluation of Moisture Susceptibility of Full-Depth Reclamation (FDR) Mixes

The Virginia Department of Transportation (VDOT) is committed to enhancing the resilience of Virginia’s transportation network in the face of changing climatic conditions and extreme weather events. The VDOT Resilience Plan outlines a comprehensive strategy to incorporate resilience measures into transportation planning, project development, delivery, operations, maintenance, and asset management. As part of this plan, VDOT is exploring a wide range of innovative solutions, including the use of advanced materials, improved construction methods, adaptive design criteria, and nature-based solutions, to align with its resilience goals. Full-Depth Reclamation (FDR) is one such technique that can offer numerous benefits and has the potential to significantly contribute to VDOT’s resilience objectives. Even though FDR, as a stabilized material, possesses higher strength and stiffness compared to unbound base/subbase layers, it is still unknown whether it is durable under fully or partially saturated conditions and retains high strength at increased moisture content during water-driven climatic events. Thus, there is a need to thoroughly evaluate the susceptibility of FDR mixes to moisture-induced damage to ensure their long-term performance and resilience under water-driven climatic events.
