Bridge Preservation Guide Maintaining a Resilient Infrastructure to Preserve Mobility

Introduction State departments of transportation (DOTs), local agencies, and other bridge owners face significant challenges in addressing the needs of their aging infrastructure. Due to limited funds and increased competition for funds among highway assets, bridge owners are challenged to cost effectively preserve and maintain their bridges to support overall highway mobility. However, having a “worst-first” approach to bridge management by focusing only on replacing poor bridges while ignoring the maintenance needs of good and fair bridges is inefficient and cost-prohibitive in the long term.

A successful bridge program seeks a balanced approach to preservation and rehabilitation/ replacement. Bridge owners are striving to be more strategic by adopting and implementing systematic processes for bridge preservation as an integral component of their overall asset management.

Purpose

This guide defines bridge preservation terms and identifies commonly practiced bridge preservation activities. It also provides guidance to State governments and other bridge-owning agencies on establishing or improving existing bridge preservation programs as part of an asset management program.

Scope

This guide is intended for Federal, State, and local bridge engineers; bridge owners; and bridge preservation practitioners to support the Federal-Aid Highway Program.

Eligibility

Over several decades, the Federal Highway Administration’s (FHWA) Highway Bridge Replacement and Rehabilitation Program (HBRRP), later known as the Highway Bridge Program (HBP), was the primary source of Federal funding for bridges. The HBP afforded State DOTs discretion to use funds not only for bridge rehabilitation and replacement, but also for a broad array of preventive maintenance activities. Bridge owners have taken advantage of the flexibilities in the HBP and have maintained their inventory in good to fair condition under constrained resources.

The Moving Ahead for Progress in the 21st Century Act (MAP-21) and the Fixing America’s Surface Transportation (FAST) Act recognized preservation as a vital component of achieving and sustaining a desired state of good repair of highway facilities. Bridge preservation is eligible for Federal funding.1 However, it is important to differentiate between routine maintenance and cost-effective preservation activities that extend the service life of a structure. Routine maintenance is not eligible for Federal funding.2

1 Section 1103 of MAP-21 amended the definition of “construction” in 23 U.S.C. 101 and adds preservation as an eligible cost of construction.

2 23 U.S.C. 116 (b)

Definitions and Related Commentaries Several definitions are presented in this section along with commentary. The definitions are offered as a means of establishing clear and consistent terminology for bridge owners and preservation practitioners.

Asset Management Definition: Asset management is defined as a “strategic and systematic process of operating, maintaining, and improving physical assets, with a focus on both engineering and economic analysis based on quality information, to identify a structured sequence of maintenance, preservation, repair, rehabilitation, and replacement actions that will achieve and sustain a desired state of good repair over the life cycle of the assets at a minimum practicable cost.”3

Commentary: MAP-21 brought transformative changes to the Federal-Aid Highway Program with its performance management and asset management requirements.4 Asset management plans are an important highway infrastructure management tool to improve and preserve the condition of assets and system performance.

Maintenance5

Definition: Maintenance describes work that is performed to maintain the condition of the transportation system or respond to specific conditions or events that restore the highway system to a functional state of operations. Maintenance is a critical component of an agency’s asset management plan that includes both routine and preventive maintenance.

Routine Maintenance Definition: Routine maintenance encompasses work that is performed in reaction to an event, season, or activities that are done for short-term operational need that do not have preservation value. This work requires regular reoccurring attention.

3 MAP-21 added this definition in 23 U.S.C. 101(a)(2).

4 The core performance management requirements are codified in 23 U.S.C. 150 and 23 U.S.C. 119. Asset management requirements are codified in 23 U.S.C. 119.

Commentary: Per 23 U.S.C. 116 (d), States and owner agencies are required to properly maintain projects financed with Federal-aid funds. Therefore, routine maintenance activities are not eligible for Federal funds. Examples of routine maintenance are listed in Table 1.

Bridge Preservation Definition: Bridge preservation is defined as actions or strategies that prevent, delay, or reduce deterioration of bridges or bridge elements; restore the function of existing

Table 1. Examples of routine maintenance activities.

These are examples of routine maintenance activities not eligible for Federal funds:

Trash, Litter, and Dead Animal Removal

Snow Removal/Application of Salt/Deicing Chemicals

Graffiti Removal Hazardous Material Removal

Asphalt Patch with No Membrane on Concrete Deck

Accident Damage to Bridge and Its Appurtenances

Storm Damage bridges; keep bridges in good or fair condition; and extend their service life. Preservation actions may be cyclic or condition-driven.

Figure 2. Bridge action categories.

Commentary: Effective bridge preservation actions are intended to delay the need for costly rehabilitation or replacement while bridges are still in good or fair condition and before the onset of serious deterioration.

Bridge preservation encompasses both cyclical and condition-based activities applied to highway structures (see Figure 2). Best practices for bridge preservation include the following:

• A needs identification method that is uniform, specific, and repeatable. It can be based on National Bridge Inventory (NBI) major component condition ratings, detailed inspections and scopes, or element-level condition data.

• A commitment by agency management to asset preservation.

• Resource allocation determined by agency network goals and a bridge management system directed to preservation actions.

• A process for categorization and/or prioritization that integrates agency objectives.

• Verification and feedback on work completed.

Preventive Maintenance Definition: Preventive maintenance (PM) is a cost-effective means of extending the service life of highway bridges.

Commentary: PM for highway bridges is a strategy of extending service life by applying cost-effective treatments to bridge elements. PM activities retard future deterioration and avoid large expenses in bridge rehabilitation or replacements.

PM includes cyclical and condition-based activities, as illustrated in Figure 2. Examples are listed in Table 2 and Table 3.

Cyclical Maintenance Activities Definition: Cyclical maintenance activities are performed on pre-determined intervals that aim to preserve and delay deterioration of bridge elements or component conditions.

Commentary: The frequency of cyclical PM activities can change as a result of environmental or condition changes. For example, superstructure cleaning that was occurring at a 3-year interval based on past accumulation of debris buildup could change if pigeons start routinely nesting on superstructure elements.

Examples of cyclical PM activities that may be considered by bridge owners for implementation on good and fair condition bridges and components are shown in Table 2.

Bridge cleaning and/or washings: Cleaning of decks, joints, drains, superstructure, and substructure elements slows the deterioration of concrete and steel elements that would otherwise be accelerated by debris, bird droppings, and contaminants.

Deck sealers: Deck sealers protect the reinforcing steel from corrosion by stopping or minimizing the intrusion of water and chloride through the concrete.

Clean and Flush Drains Deck

Clean Joints Deck Deck/Parapet/Rail Sealing and Crack Sealing Deck

Seal Concrete Super/Substructure

Condition-Based Maintenance Activities Definition: Condition-based maintenance activities are performed on bridge components or elements in response to known defects. Condition-based maintenance improves the condition of that portion of the element, but may or may not result in an increase in the component condition rating.

Commentary: Condition-based maintenance activities are identified through an inspection process.

Condition ratings may be improved by a condition-based PM activity. One example is a substructure element that was once rated fair due to spalled concrete and exposed reinforcement.

After maintenance removed loose concrete, cleaned the exposed reinforcement, and formed and placed new concrete, the inspection rating for the substructure was changed to good condition.

Examples of condition-based maintenance activities that may be considered by bridge owners for implementation on fair condition bridges and components are shown in Table 3.

Halo Effect

The “halo effect” (see Figure 5) in bridge decks results when a delaminated area (due to reinforcement corrosion resulting from chlorides and moisture in the concrete) is removed and repair material (containing no chlorides) is put in its place. If a high concentration of chlorides remains in the area surrounding the replaced concrete, the corrosion potential will lead to rapid corrosion in the area surrounding the repair.

Rehabilitation6

Definition: Rehabilitation involves major work required to restore the structural integrity of a bridge, as well as work necessary to correct major safety defects.

Commentary: Bridge rehabilitation projects provide complete or nearly complete restoration of bridge elements or components. Rehabilitation work can be done on one or multiple elements and/or components of a structure. Agencies may choose to combine preservation activities on several elements while a component is being rehabilitated. These projects require significant engineering resources for design, a lengthy completion schedule, and considerable costs.

Examples of bridge rehabilitation include, but are not limited to: partial or complete deck replacement, superstructure replacement, and substructure/culvert strengthening or partial/full replacement.

Incidental widening is often associated with some of these activities.

Replacement Definition: Total replacement of an existing bridge with a new facility constructed in the same general traffic corridor.

Commentary: The replacement structure must meet the current geometric, construction, and structural standards required for the types and volume of projected traffic on the facility over its design life. Replacement includes a nominal amount of approach work sufficient to connect the new facility to the existing roadway or to return the grade line to an attainable touchdown point.

Similar to bridge rehabilitation, bridge replacement projects require engineering resources for design, a substantial and complex completion schedule, and considerable costs. Life-cycle costs and other economic factors are usually considered when weighing rehabilitation versus replacement costs.

Summary Table 4 summarizes actions that are either eligible or not eligible for Federal funds.

National Bridge Inventory General Condition Ratings NBI general condition ratings (GCRs) are used to describe the existing, in-place bridge or culvert as compared to the as-built condition. The materials used in the bridge are considered, as well as the physical condition of the deck, superstructure, and substructure components. This information is used to determine GCRs on a numerical scale that ranges from 0 (failed condition) to 9 (excellent condition) as described in the FHWA Coding Guide.7

Appendix A provides a description for each of these numeric values. The GCRs are used in evaluating bridge decks (NBI Item 58), bridge superstructures (NBI Item 59), bridge substructures (NBI Item 60), and culverts (NBI Item 62).
