Aging of the bridge infrastructure inventory has caused Department of Transportation agencies to critically focus on bridge preservation and replacement needs, while often faced with constrained or reduced budgets every year. A strategic bridge preventive maintenance program has been shown to be an effective way to preserve and extend bridge service lives. A bridge preventive maintenance program is related to routine practices that are repeated with some particular frequency to obtain the best results. Moreover, it is well known that frequently performing less-costly preventive maintenance activities results in a more efficient alternative than performing fewer expensive repairs/rehabilitation or even replacements of bridge elements. The objective of this research was to review bridge maintenance activities recommended by specialized literature, to examine maintenance activities currently conducted by the various INDOT districts, and also to review maintenance activities performed by several other DOT agencies. Based on the results of this review, a list of ten new and enhanced bridge preventive maintenance activities was identified to improve the effectiveness of bridge maintenance operations in Indiana. The required conditions and frequency to perform each activity was analyzed, and the cost and benefit of such operations was studied to ensure that the proposed activities are economically feasible and sustainable.
This guide provides bridge related definitions and corresponding commentaries, as well as the framework for a systematic approach to a preventive maintenance program. The goal is to provide guidance on bridge preservation. This guide is intended for Federal, State, and local bridge engineers, area engineers, bridge owners, and bridge preservation practitioners.
The primary objective of this project is to identify several common bridge deck maintenance activities that are performed by contract, review the current Arizona Department of Transportation (ADOT) specifications for those maintenance activities, modify the specifications where appropriate to reflect current accepted practice, and serve as a model to guide future efforts at updating specifications. To complete the project, all of ADOT's bridge deck maintenance specifications were reviewed. The following repairs were identified for further evaluation: (1) Temporary repair of expansion joints; (2) Minor collision damage repair of concrete I-beam girders; (3) Hole in deck repair (with and without asphalt overlay); and (4) Bridge railing repair (concrete and aluminum). Bridge preservation specifications from other agencies were then collected and reviewed. This led to the selection of two treatments to develop new draft specifications: (1) Bridge Deck Repair: Full-Depth Patch; and (2) Prestressed Concrete I-Beam: Minor Repair by Patching and Epoxy Resin Base Adhesive Injection. Draft specifications were developed and submitted to ADOT for review and possible implementation, thereby completing the project.
The most recently published update of the Virginia Department of Transportation’s (VDOT’s) historic bridge management plan, A Management Plan for Historic Bridges in Virginia: The 2017 Update, noted a number of special considerations regarding stone masonry on VDOT’s historic bridges (i.e., those state-owned bridges that are individually eligible for or listed on the National Register of Historic Places). Key considerations included the types of masonry work identified on management plan bridges; various types of repair and stabilization methods; and references to compatible mortars for use on bridges of older construction. The 2017 update of the historic bridge management plan also contained a fifth recommendation: conduct an in-depth historic masonry study and produce a best practices document identifying procedures for repair and/or rehabilitation of historic masonry structures and masonry components, particularly those on VDOT’s historic bridges. This study addressed that fifth recommendation. This study assembled data related to masonry in historic bridges, including archival documentary evidence, materials, and construction and repair technologies, and yielded a best practices document for facilitating appropriate management of VDOT’s historic bridges with stone masonry components. The study concluded that (1) historic bridges in Virginia with stone masonry construction exhibit a number of different forms, materials, building practices, and technologies that reflect the time periods when the bridges were built; (2) a variety of maintenance, repair, and rehabilitation practices have been used on these bridges; (3) best practices in historic preservation can evolve over time as additional information is acquired; and (4) knowledge of these various forms, materials, practices, and technologies, and the necessary specialized treatments required, must be taken into account when planning and undertaking maintenance, repair, and rehabilitation for the various types of stone masonry construction found in Virginia’s historic bridges. Using the most appropriate practices as outlined in this report may help avoid inappropriate repairs and damage to stone masonry elements. The study recommends that (1) the practices regarding bridge maintenance, repair, and historical documentation described in this report be used by VDOT structure and bridge engineers, environmental cultural resource personnel, and corresponding district staff; and (2) the information, including historical background, condition, and maintenance needs on specific bridges, included in this report be referenced in the forthcoming update of A Management Plan for Historic Bridges in Virginia (now in progress).
Developed by the American Association of State Highway and Transportation Officials (AASHTO) Committee on Bridges and Structures, this Guide is intended to offer guidance on selecting specific, cost-effective preservation and maintenance actions and treatments for agencies wishing to extend service life and estimate needed budgets to optimize performance of bridge inventories. It can be used to help preserve bridges and extend their service life by selecting cost-effective actions and treatments for various bridge elements based on exposure. Specifically, the Guide identifies candidates for bridge preservation; lists actions in bridge preservation; lists costs of actions and time intervals for use of actions; and presents a method of Preservation-Cycle Cost Analysis for cost evaluation of preservation actions, used to compute monetized benefits of preservation.
Highway departments around the world are faced with the dilemma of providing improved operations on a "shoe string budget".

"This guide outlines preservation treatments, including deck overlays, surface sealers, and deck repairs, that can extend the life of bridge decks in service, and presents the factors in deck capacity and durability that can influence the identification of candidates for deck preservation. The guide is designed for use on decks in fair or good condition with significant remaining service life. Highway bridge decks often are exposed to severe loading conditions, both in terms of live load application and environmental exposure that may include the application of de-icing chemicals that can accelerate deck deterioration. Agencies implementing preservation treatments for highway bridge decks appropriately can expect to extend the service life of those decks and optimize preservation budgets. The guide includes over 20 highway bridge deck preservation treatments, outlining conditions when the treatment is appropriate and constraints on the treatments usage."--Publisher website
