Guidelines for Design and Construction of Segmental Bridges for Rail, April 2022

Price: FREE

The purpose of this document is to provide guidance to the industry (owners, designers, suppliers, contractors, and others) on considerations when using a concrete segmental-type bridge to carry rail, including transit rail, heavy or freight rail, and high-speed rail.  To date, most segmental rail projects in North America have been transit jobs and therefore, the guidelines herein are presented with a predominantly transit background.  The current document applies to structures supporting all rail types in general.  This guideline may be amended in the future to incorporate additional considerations for heavy or high-speed rail if warranted.

Construction Practices Handbook for Concrete Segmental and Cable-Supported Bridges 3rd Edition, July 2019

Price - FREE

This “How-To Handbook” was developed to provide guidance for construction of concrete segmental bridges. Although the segmental construction concept is generally very simple, the construction technology involved is, in numerous ways, more demanding than that required for other types of technology used in the industry. The use of concrete segmental bridge construction continues to grow throughout the United States and Canada. Increased use of this technology has led to a need to provide industry standard information for use by contractors, inspectors, quality control staff, and owners. In the interest of educating the industry, sharing best practices, and standardizing methods, this handbook is intended to provide a basic understanding of segmental construction technology. The overall goal is to facilitate the construction process, avoid common difficulties previously encountered, and reduce impacts to projects. This handbook is intended to be an industry guide aimed at focusing on specific aspects of the technology based on past experience.

American Segmental Bridge Institute Grouting Committee Interim Statement on Grouting Practices

Price: FREE

The American Segmental Bridge Institute (ASBI) Grouting Committee was formed in October 2000 to provide an industry response to recent problems reported with grouted tendons on four bridges in Florida.

Design and Construction of Concrete Segmental Bridges

Price: FREE

Segmental concrete bridges are economical, durable, and aesthetically pleasing while providing minimum impact to traffic and the surrounding environment both during and after construction.

Guide Specifications for Design and Construction of Segmental Concrete Bridges (1989 Edition)

This document contains guidelines for the design and construction of segmental concrete bridges.  The guidelines are comprehensive in nature and embody several new concepts which are significant departures from previous design and construction provisions.  They are formulated and based on both observed performance of bridges of this type and on recent research conducted in the United States and abroad.

This publication is only available to ASBI members and may be downloaded through the Members Only section.

No copies of the specification will be sold commercially, disseminated elsewhere in print or online, modified, or used to create derivative documents.  Anyone seeking to duplicate the document in part or in its entirety will need to contact AASHTO to request such permission.

Guide Specification for Grouted Post-Tensioning

This document includes all aspects of materials, installation, stressing, and corrosion protection levels for grouted post-tensioning systems. Requirements for field personnel are also stated as the knowledge of all involved contributes to building durable structures. The aim is to have this new Specification adopted by most State Departments of Transportation (DOT), simplifying the approval process for the systems used in different areas of the country while allowing for local environmental conditions. Also designers will find this book useful in preparing the Project Specifications.

Segmental Bridges Offer Benefits To California

Price: FREE

Durability has become a key issue for state bridge officials as they determine the best design solutions for each unique situation. In California, segmental concrete bridge designs are used in a variety of situations that play to their strengths and offer high durability.

Concrete Segmental Bridges Retrofit Ends Michigan Moratorium

Price: FREE

Engineers at the Michigan Department of Transportation (MDOT) put a moratorium on designing concrete segmental bridges after a complex project in the 1980s resulted in a major accident during construction. When recently returning to retrofit this and another bridge they discovered the long-term durability that segmental bridges can offer—and they lifted the moratorium.

TxDOT’s Long History With Segmental Concrete Bridges Continues

Price: FREE

Through the past four decades, the Texas Department of Transportation (TxDOT) has relied on segmental concrete bridge technology to resolve a variety of key design and construction challenges. Those began in the early 1970s with the construction of the John F. Kennedy Causeway over the Gulf Intracoastal Waterway, near Corpus Christi. This causeway included the first precast concrete segmental bridge in the United States.
