concrete bridge deck overlays. This overlay system was developed by Caltrans and has been primarily used in California and Nevada with several installations in New York. These overlays are designed to be installed at approx 1in. thick and use vibrating screeds to finish. HMWM is required as a primer for all polyester overlays. The first step is to install the bridge abutments. We will excavate a coffer dam the site for the concrete bridge foundation, pour concrete and finish the bridge using whichever deck technique fits the application. We have built bridges using a steel deck and gravel on top of the beams as well as installed a wood deck for a more rustic look.
Design of Concrete Bridge Deck Rehabilitation. Introduction. Bridge decks are a main structural component designed to carry vehicle traffic and transfer live load to the girder system. In addition to safely carrying vehicle loads, the bridge deck must also withstand the application of road salt, abrasive forces and varying climaticFile Size: 38KB. The authors discuss why the use of standard bridge deck designs is not always possible on bridge rehabilitation projects. This practical reference will aid busy engineers in dealing with the major changes that will mandate much greater attention to deck selection and design in the future.

Chapter 40 – Bridge Rehabilitation January General New bridges are designed for a minimally expected life of 75 years.
Preliminary design considerations are site conditions, structure type, geometrics, and safety. Refer to Bridge Manual Chapters 9 and 17 for Materials and Superstructure considerations, Size: 1MB. Quick assembly of bridges has advanced in the recent years, in part through the use of superstructure proprietary systems for new bridges and bridge rehabilitation, such as: CONSPAN: A complete assembled small-span reinforced concrete bridge.
Inverset: The method uses composite rolled steel joists and concrete deck panels. Prefabricated deck. This Design Memorandum summarizes revisions to the bridge deck protection system and future overlay requirements. The recent implementation of wide flange deck girder (WF-DG) girders with ultra high performance concrete (UHPC) connections requires changes to File Size: KB.
repair of concrete bridges was developed using Microsoft Access. A limited, first version of an expert system computer program, Concrete Bridge Assessment and Rehabilitation (ConBAR), was developed to assist in diagnosis of concrete bridge deterioration problems and to identify repair, rehabilitation, or preventative maintenance options.
RAPID REPLACEMENT OF BRIDGE DECKS. This report contains the findings of a study that was performed to evaluate existing rapid bridge deck replacement methods and to develop better procedures and new superstructure designs for future rapid deck replacement.
The report provides a comprehensive description of the research, including the details of Cited by: A baseline for an accelerated bridge deck joint replacement was established by observing various joint repair and rehabilitation construction projects including a staged weekend replacement.
Rehabilitation of RC, Steel and Pre-stressed Bridges. Introduction. Modern bridge infrastructure comprises of primarily concrete (reinforced or pre-stressed) and steel structures.
Over the service life of a bridge, its constituent materials are continually subjected to fatigue and wear-tear due to dynamic vehicular loads. Overloading due to. Get this from a library. Concrete bridge protection, repair, and rehabilitation relative to reinforcement corrosion: a methods application manual.
[Richard E Weyers; Strategic Highway Research Program (U.S.);] -- This manual is a practical guide for state highway agency personnel who are faced with the day-to-day task of cost-effectively protecting repairing, and rehabilitating concrete. The rehabilitation study committee recommends that Alternatives 1 and 2 are viable alternatives for the rehabilitation of Bridge Each has two optional work items: passive cathodic protection of the concrete slab, and lowering TH 61 by about 10 to improve vertical clearance.
Bridge decks require protection from chloride ion intrusion from de-icing salts, as well as freeze-thaw cycles and traffic erosion over time.
BASF offers a wide vari-ety of products to protect bridge decks ranging from water repel-lents to thin polymer overlays. The ultimate goal is to have a concrete deck free of deterioration, keepingFile Size: KB. It does not cover repair, rehabilitation, reconstruction, or bridge inspection, and therefore, it does not include topics such as cathodic protection, repair with shotcrete, and deck overlays.
Detailed methods of repairing and inspecting bridges may be found in the references. Concrete bridge maintenance is defined as those activities that are. A bridge floor is the entire length of the bridge from the roadway side of the mudwall or pile cap to the other roadway side of the mudwall or pile cap and the entire width from one coping edge across to the other coping edge.
(The bridge deck is the roadway portion of a bridge, including shoulders.). Polymer concrete bridge deck overlay systems. Polymer concrete bridge deck overlay systems repair the underlying deck after removal of an existing overlay and placement of a new overlay to seal out moisture and chloride ions and prevent them from permeating into the deck.
Generally, these overlay systems have a year life span. Rapid bridge construction is gaining more attention among department of transportation officials.
Using fast-setting hydraulic cement and super sacks of sand as the forms/cofferdams for the. Concrete Bridge Rehabilitation & Restoration Vector Construction has extensive experience in multi-faceted concrete bridge rehabilitation and restoration projects throughout Canada and the U.S.

Sprinkel Publication: Symposium Paper Volume: Issue: Appears on pages(s): Keywords: overlays, polymer modified concrete, bridges, decks, latex, silica fume Date: 3/1/ Abstract: Hydraulic cement concrete overlays made with latex-modified concrete (LMC) and silica fume concrete (SFC) are typically used to extend Cited by: 1.
CONCRETE BRIDGE PROTECTION AND REHABILITATION: CHEMICAL AND PHYSICAL TECHNIQUES. SERVICE LIFE ESTIMATES. This report presents a study on estimating the service life cycle of reinforced concrete bridge components exposed to chloride-laden environments.
Current treatment options are identified and an opinion survey was used to obtain first Cited by: permeability of the original concrete. In addition, the bridge had a highly flexible deck with centre span deflections up to 50 mm under normal traffic loads.
However, these deflections met the design criteria and the structural codes of the early í97 ì’s. A major repair and rehabilitation program was planned in and was implemented in.

Consequently, decks may require more maintenance and repair than other bridge components. Concrete bridge decks resist wear and weather well, provide good traction and ride quality, and in many designs provide a part of the structural strength of the bridge.
