Abstract
This article reviews and discusses the design and reconstruction of concrete pavement projects on the U.S. Interstate System, focusing on the use of Portland cement concrete. The adoption of the 1982 Surface Transportation Assistance Act's 4R fund has facilitated significant advancements in reconstruction methods. Various projects across different climates in the United States are examined, including complete replacements, full-depth unbonded and partial-depth bonded overlays, and the recycling of old concrete as aggregate for new pavements. The paper highlights innovative equipment and techniques that have emerged as a result of increased funding and legislative support, aimed at addressing the challenges posed by heavy commercial traffic and the need for durable road infrastructure. Economic factors, life-cycle costing, and material reuse are also discussed as critical considerations in the decision-making process for pavement reconstruction. The effectiveness of these projects is assessed in terms of technical feasibility and long-term economic benefits, emphasizing the importance of continued funding and research to support future infrastructure demands.
