POCKET GUIDE A User’s Guide to Latex Modified Concrete Bridge Deck Overlays

This guide is developed to encourage a better understanding of the installation process for Latex Modified Concrete (LMC) overlay systems. When installed properly, these systems provide long-term preservation of concrete bridge decks. The
LMC overlay can serve as either a preservation or rehabilitative treatment. The bridge deck must be appropriately prepped ahead of the LMC overlay. The concrete is typically batched and dispensed on-site with a mobile volumetric-type mixer. A
saturated surface dry (SSD) condition, with or without a bonding grout, is required ahead of the placement. The LMC system is most normally placed 1¼ to 3 inches in nominal thickness, although thicker applications may be used. The application of an
LMC overlay requires a sound substrate to achieve optimal performance.

POCKET GUIDE A User’s Guide to Low Slump Concrete Bridge Deck Overlays

This guide was developed to encourage a better understanding of the installation process for a Low Slump Concrete (LSC) overlay system. When installed properly, this system provides for the long-term preservation of concrete bridge decks. The
LSC overlay can serve as either a preservation or rehabilitative treatment. The bridge deck is prepped ahead of the LSC overlay. The LSC is typically batched at an on-site plant and dispensed through buggies or a stationary or mobile volumetric-type
mixer. Depending on the preparation method and overlay type, a saturated surface dry (SSD) condition and/or a bonding grout may be required ahead of the placement. The LSC overlay is most normally placed 1¾ to 4 inches in thickness, although
thicker applications may be used. The application of an LSC overlay requires a sound substrate to achieve optimal performance.

POCKET GUIDE A User’s Guide to Supplemental Cementitious Material Concrete Bridge Deck Overlays

This guide is developed to encourage a better understanding of the installation process for the various Supplemental Cementitious Materials Concrete (SCMC) Overlay systems. Supplemental cementitious materials include Microsilica Concrete (MSC), Ready-mix Supplied High-Performance Concrete (RSC), Fly Ash Concrete (FAC) or Ground Granulated Blast-Furnace Slag Concrete (GGBFSC). When installed properly,
these systems provide long-term preservation of concrete bridge decks. The SCMC overlay can serve as either a preservation or rehabilitative treatment. The bridge deck is prepped ahead of the concrete overlay. The concrete is typically batched at a concrete plant and dispensed with a ready-mix truck. Depending on the preparation method and overlay type, a saturated surface dry (SSD) condition and/or a bonding grout may be required ahead of the placement. The SCMC overlay system is most normally placed 2 to 4 inches in thickness, although thicker applications may be used. The application of an SCMC overlay requires a sound substrate to achieve optimal
performance.

POCKET GUIDE A User’s Guide to Ultra-High Performance Concrete Bridge Deck Overlays

This guide was developed to encourage a better understanding of the installation process for the Ultra-High Performance Concrete (UHPC) overlay system. When installed properly, this system provides for the long-term preservation of concrete
bridge decks. An UHPC overlay can serve as either a preservation or rehabilitative treatment significantly extending the life of an existing infrastructure. The bridge deck must be appropriately prepared ahead of the UHPC overlay installation. The UHPC is typically batched at an on-site plant and dispensed through buggies or mobile drum type mixers. Depending on the preparation method, a saturated surface dry (SSD) condition is required ahead of the placement. The UHPC overlay is most normally placed between 1.5 to 4 inches in thickness. The application of a UHPC overlay requires a sound substrate to achieve optimal performance.

POCKET GUIDE A User’s Guide to Maintenance and Repair of Bridge Bearings

This bridge bearing pocket guide has been developed to provide a summary of the preservation actions for both preventive maintenance and repair options. This guide
describes steel (sliding, rocker and roller) and elastomeric bearings but does not cover the preservation actions of complex or less commonly used bearings, such as nested roller bearings or High Load Multi-Rotational bearings (e.g., pot, spherical or disc bearings). The focus of this guide is on bearing preservation actions that might typically be performed by DOT maintenance staff.  However, some bridge owners may consider replacing bearings if their preservation would not be cost effective, especially considering ancillary costs such as maintenance of traffic.

POCKET GUIDE A User’s Guide to Removal and Replacement of Bridge Coatings

This guide has been developed to encourage a better understanding of the process to completely remove and replace bridge coatings for the structural steel elements of bridges in service. The guide describes how to plan and execute a coatings removal and replacement operation with an emphasis on the three primary activities of containment, surface preparation and painting. This guide does not cover shop applied coatings or spot painting operations, however much of the information presented represents best practices for all bridge coating work.

POCKET GUIDE A User’s Guide to Spot, Zone, and Overcoating Existing Bridge Coatings

This guide is designed for bridge preservation practitioners undertaking spot, zone and overcoat painting projects. These coating strategies can extend the service life of the original coating and are normally simpler to implement than full removal and replacement. For this reason, they can offer economic and environmental advantages when site-specific details are appropriate. Properly specified and applied coatings exhibit maximum corrosion protection. Defects in the coating system will lead to premature corrosion of the steel. Corrosion is accelerated by increased temperatures, higher relative humidity (or exposure to moisture), and the presence of pollutants such as soluble salts. Owners utilize spot, zone and overcoating strategies to reduce overall costs associated with maintaining a steel bridge structure. Owners should consider life cycle costs when contemplating a coating remediation strategy.
