Pavement Structural Evaluation and Design of Full-Depth Reclamation (FDR) Pavement

This pavement preservation topic has gained significant attention from pavement practitioners in the United States along with important support from the Federal Highway Administration, which has enabled several programs in pavement preservation. In the current SAFETY-LU and the upcoming Transportation Bill, the emphasis is on transportation infrastructure issues such as pavement preservation and faster rehabilitation/re-construction with the significant topic of the renewal of infrastructure. Preservation of the existing transportation system requires rehabilitation and re-construction techniques that reduce congestion during construction. However, there is need not only of faster construction, but also of more durable pavement that reduces both agency costs and costs to the traveling public. One of the faster pavement construction techniques is FDR (Full-Depth Reclamation). An evaluation project was initiated by INDOT Research and Development to estimate the structural contribution and feasibility of FDR bases for pavement structure under low to medium volume traffic loading. FWD (Falling Weight Deflectometer) tests were conducted, and the layer moduli were back-calculated during different construction phases on the surface of existing HMA (Hot Mixed Asphalt) pavement, the FDR base, the new HMA final surface, and post-construction testing at 9, 20, and 35 months. The results indicated promising results of this recycled base material in pavement construction compared to traditional granular base. This evaluation result indicated that the MEPDG (Mechanistic Empirical Pavement Design Guide) provided comparable thickness to the 1993 AASHTO Pavement Guide if the failure criteria are set reasonably.
