Field Evaluation of Pavement Rehabilitation Using Full-Depth Reclamation
Historically, highway pavement rehabilitation methods employed by the Rocky Mountain Region of the Bureau of Indian Affairs (BIA) have included either conventional overlays or full depth reconstruction. In the case of overlays, approximately 6.35 cm (2 ½ in) of Hot Mix Asphalt (HMA) are typically placed over the existing pavement surface. For the reconstruction option the entire pavement structure is replaced. In an effort to explore alternative pavement rehabilitative methods, BIA personnel are evaluating the use of Full-Depth Reclamation (FDR) as a method that may prove to be more cost-effective, while extending the use of available material resources. Pavements that have experienced base failure are considered ideal candidates for FDR. With FDR, a single process is used to correct all surface distresses and base deficiencies. Additionally, corrections to the existing pavement cross-section can be accomplished concurrently with the rehabilitation of the pavement, if required. It is envisioned that FDR may provide the BIA with a viable alternative to current pavement rehabilitation methods with a savings in life-cycle dollars. To evaluate the potential of adding the FDR tool to the BIA's repertoire, a demonstration project was constructed in 2003. Non-destructive testing including Dynamic Cone Penetrometer (DCP) and Transverse Profilograph are being employed to track the relative deterioration of the reclaimed pavement sections. Visual pavement distress observations are also being used. This paper documents the preliminary performance of the different test sections and provides an example of the application of FDR versus conventional pavement rehabilitation methods in terms of cost and performance.
