The National Research Council is jointly administered by the National Academy of Sciences, the National Academy of Engineering, and the Institute of Medicine. The mission of the Transportation Research Board is to provide leadership in transportation innovation and progress through research and information exchange, conducted within a setting that is objective, interdisciplinary, and multimodal. The Transportation Research Board is distributing this Circular to make the information contained herein available for use by individual practitioners in state and local transportation agencies, researchers in academic institutions, and other members of the transportation research community. The information in this circular was taken directly from the submission of the authors. This document is not a report of the National Research Council or the National Academy of Sciences.

Weeks, Layout Preface his circular is an update to Transportation Research Circular 494: Durability of Concrete, T published in 1999, originally authored by Bryant Mather, V. Ramakrishnan, Steven H. Kosmatka, D. Stephen Lane, H. Celik Ozyildirim, and David L. Rettner. This revised publication is intended to provide the latest information for consideration by practitioners on producing durable concrete for transportation structures and pavements. Considering the number of facilities that have required repairs and reconstruction before reaching their intended service life, as well as the cost of the rehabilitation and the inconveniences to the traveling public, the importance of constructing long-lasting bridges and pavements continues to capture national attention and remains a high-priority item. This document is divided into sections introducing each topic and discussing the production of durable concrete through materials selection, proportioning, construction practices, specifications, and testing. Also included is a section of case studies, providing examples of problems encountered in the field that involve concrete pavement and bridges, along with the proposed solutions by the authors of the studies. Special appreciation is expressed to Peter Taylor for overall editing and to Paul Tennis for his work in updating the Introduction, Materials Selection, Proportioning, and Testing sections. Sincere thanks are expressed to Karthik Obla for his work in updating the Specifications portion and to Prashant Ram for his work in updating the Construction Practices section. The work Thomas Van Dam did on the Case Studies section and that Heather Dylla did in updating the References is greatly appreciated. In addition, many committee members and friends of the committee who have an interest in the subject and experience in the field made significant contributions. The Durability of Concrete Committee welcomes suggestions from readers and practitioners for future updating of the information. —Tyson D.
