One of the biggest challenges that public agencies face is how to optimize available funding. With the price of bituminous materials 70% higher than 2 years ago and increased demand for capacity improvement projects, it is more important than ever to use in-place materials when rehabilitating pavement structural sections. Cold in-place recycling (CIR) and full-depth reclamation (FDR) are two pavement rehabilitation strategies that the Nevada Department of Transportation (NDOT) has used for more than 20 years. These strategies have allowed NDOT to save more than $600M over the past 20 years compared with complete reconstruction costs. In addition, traffic interruptions are minimized during construction, and natural resources are preserved. According to the Highway Performance Monitoring System data, NDOT has the highest percentage of its combined National Highway System Interstate and other roadways rated in the “good” category. The reason for this achievement is that NDOT uses a proactive Pavement Management System (PMS) to prioritize its pavement preservation projects. A considerable amount of CIR and FDR rehabilitation work is performed in conjunction with the proactive PMS. Because these strategies are more cost-effective than overlay, mill and overlay, or reconstruction, NDOT can rehabilitate more roads with less money. This report will describe how to select, design, and construct successful CIR and FDR projects. The performances of the strategies are evaluated, and life-cycle cost analysis is developed to demonstrate the cost–benefit of CIR and FDR versus conventional rehabilitation strategies.
