Guidelines for Early-Opening-to-Traffic Portland Cement Concrete for Pavement Rehabilitation
Author: Van Dam, T J | Size: 377 KB | Format:PDF | Quality:Original preprint | Publisher: Transportation Research Board | Year: 2005 | pages: 36 | ISBN: 0309088356
This report presents guidelines to facilitate highway agencies' use of "early-opening-to-traffic" (EOT) concrete for pavement rehabilitation, thereby reducing pavement closure and accruing economic and environmental benefits. These guidelines address the proportioning, testing, construction, and other aspects of EOT concrete. This report will be of particular interest to engineers, researchers, and others concerned with the construction and rehabilitation of concrete pavements. Chapter headings are as follows: Introduction; State of the Practice for EOT Concrete Repairs; Performance Considerations Related to the Durability of EOT Concrete; Materials and Mixture Design Considerations; and Testing of Fresh and Hardened Concrete.

This report describes the transportation planning process and discusses where and how environmental factors can be addressed effectively at the state and metropolitan levels. This report should be especially useful to federal, state department of transportation (DOT), metropolitan planning organization (MPO), and local transportation planners, as well as other practitioners concerned with addressing environmental factors within transportation systems planning, priority programming, and project development planning leading to implementation. The research focused on environmental issues within the long-range transportation planning processes of state DOTs and MPOs and included the following: (1) a comprehensive review of recent literature; (2) a survey of approaches employed by state DOTs, MPOs, and environmental regulatory agencies; (3) a review of federal regulations and guidance on environmental factors; and (4) case studies to synthesize current practice in environmental planning.

Simplified Shear Design of Structural Concrete Members
Author: Hawkins, Neil M | Size: 3.16 MB | Format:PDF | Quality:Original preprint | Publisher: Transportation Research Board | Year: 2005 | pages: 62 | ISBN: 0309088445
This report contains the findings of research performed to develop practical equations for design of shear reinforcement in reinforced and prestressed concrete bridge girders. Recommended specifications, commentary, and examples illustrating application of the specifications were also developed. The material in this report will be of immediate interest to bridge designers. The objective of this research was to supplement the Load and Resistance Factor Design (LRFD) methods for shear design with procedures providing a direct solution for transverse and longitudinal reinforcement of concrete structures of common proportions. This work focused on development of resistance equations that yield unique solutions with defined limits of applicability. The recommended equations are similar in format and application to the resistance equations currently found in the AASHTO Standard Specifications. The equations apply to conventional structure types such as reinforced concrete T-beams, prestressed concrete I girders continuous for live load, prestressed concrete box beams, cast-in-place post-tensioned box girders, hammerhead piers and footings, and multi-post reinforced concrete bents and footings. The recommendations for additions to the LRFD specifications apply to precast concrete strengths up to 18 ksi and cast-in-place concrete strengths up to 10 ksi.

Development of LRFD Specifications for Horizontally Curved Steel Girder Bridges
Author: Kulicki, John M | Size: 1.00 MB | Format:PDF | Quality:Original preprint | Publisher: Transportation Research Board | Year: 2006 | pages: 83 | ISBN: 0309098556
This report contains the findings of research performed to develop design specifications for horizontally curved steel girder bridges. The developed specifications have been adopted by the American Association of State Highway and Transportation Officials (AASHTO) and are included in the 2005 Interims to the third edition of the AASHTO "LRFD Bridge Design Specifications." Detailed examples showing the application of the specifications to the design of an I-girder bridge and a box-girder bridge are available from AASHTO. The material in this report will be of immediate interest to bridge designers.

Best-Value Procurement Methods for Highway Construction Projects
Author: Scott III, Sidney | Size: 2.54 MB | Format:PDF | Quality:Original preprint | Publisher: Transportation Research Board | Year: 2006 | pages: 214 | ISBN: 0309098580
This report contains tools for use in awarding best-value highway construction contracts. This report will be of immediate interest to professionals involved in the procurement of highway construction contracts. Under a best-value selection process, the low-bid concept can be modified by adding quality issues to the bid evaluation process. A best-value bid award system can provide a means for both public- and private-sector organizations to achieve common objectives and to include quality in the competitive procurement process.
