Federal Highway Administration.] -- This synthesis will be of interest to maintenance engineers, bridge engineers, and others interested in methods and procedures for removing concrete from bridges.

Information is provided on equipment and procedures used by states to remove concrete from highway bridges. Repairing structural concrete involves removal and replacement of deteriorated concrete. This report of the Transportation Research Board describes the equipment and procedures used for both complete and partial removal of concrete from bridge decks and substrates.

• Removing bridge decks takes about the same amount of time as removing entire superstructures when bridges are over waterways • Bridge deck removal takes longer and is more delicate work than removing the entire superstructure or bridge • Concrete deck replacement is more economical thanFile Size: KB.

Removal or Revisions to Bridge Deck Joints. Remove or extend and modify existing bridge deck joints. Clean structural steel exposed during concrete removal in accordance with SSPC-SP3, Power Tool Cleaning.

Methods for Removing Concrete Decks from Bridge Girders, TR Abstract With ever tightening budgets and limitations of demolition equipment, states are looking for cost-effective, reliable, and sustainable methods for removing concrete decks from bridges.

The goal of this research was to explore such methods.

Book collection consist of structural design and construction of concrete, steel and composite bridges including Cable-stayed bridges, Suspension bridges, Truss bridges, Beam bridges etc.

If you do it yourself, the cost to remove a concrete driveway will run you about $, including rental and disposal.

That’s a savings of about $1, on the cost to remove a concrete driveway. On the other hand, if you’re hiring a contractor to pour new concrete, doing the demo yourself could actually cost you more once you pay disposal : The Family Handyman. 3) Bridge railings (parapets), handrails, sidewalk, lighting, and some drainage features.

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 removal of formwork also called as strike-off or stripping of formwork should be carried out only after the time when concrete has gained sufficient strength, atleast twice the stress to which the concrete may be subjected to when the formworks are removed.

It is also necessary to ensure the stability of the remaining formwork during formwork removal. Repair Manual for Concrete Bridge Elements Page 1 Introduction Concrete girders are frequently damaged by over-height impacts, fire or corrosion.

Minor damage to the girders can consist of cracking or shallow spalls, whereas serious damage can extend to concrete, reinforcing steel and prestressing steel. Minor damage can affectFile Size: 1MB. The removal of a reinforced concrete arch includes the removal of all of the pavement and backfill of the arch.

Blasting should only be used in the demolition of es if allowed by Local bridgFile Size: 1MB. Automated concrete removal at the ceiling of the bridge. To break off large pieces, make a series of blows in a line to create a stress crack, then strike in the middle of the area you want to remove to break the concrete along the line.

The size of the chunks you remove is limited by your ability to lift and dispose of the concrete. With innovative and experienced employees, we build our own state-of-the-art equipment for use on surface cleaning projects, including airplane tire rubber removal on runways, to the demolition and removal of reinforced concrete on dams, bridges, parking garages, and other structures.

Basic labor to remove concrete slab with favorable site conditions. Jackhammer concrete into movable pieces. Remove all concrete and reinforcing material. Includes planning, equipment and material acquisition, area preparation and protection, setup and cleanup. square feet: $ $ Concrete Slab Removal Equipment Allowance.

Concrete bridges should be tested if the bridge inspection reported doubts regarding the structural performance of the existing structure. The tests available range from the completely nondestructive, through those where the concrete surface is slightly damaged, to partially destructive tests, such as core tests and pullout and pull off tests, where the surface has to be repaired after the test.

Get this from a library. Techniques for concrete removal and bar cleaning on bridge rehabilitation projects. [Michael C Vorster; Strategic Highway Research Program (U.S.)] -- The report addresses the partial removal of concrete from decks and other parts of bridge structures.

Three technologies are identified as being of particular importance and these are studied in.

To allow for automated headings and cross references. Use a sledgehammer for thin slabs. If your concrete is 4 in (10 cm) thick or less, try using a sledgehammer. Start at any existing cracks or at a corner or edge, and keep in mind that thick concrete will be easiest to break closer to its outer edges.

Don’t try to swing the sledgehammer or lift it above your head; hold it at shoulder-height and let it fall onto the concrete, instead%(4). If you have recently finished a concrete project--perhaps a sidewalk or driveway--only to find that someone has written their name on it, don't despair.

With a concrete resurfacer you can quickly repair your concrete without having to replace a large piece or completely redo the project.

The objective of this work is to determine and/or develop new cost-effective and efficient deck removal techniques for steel superstructure bridges.Before removing deteriorated concrete, isolate the area from adjacent concrete and shoulder materials using full-depth saw cuts.

The full-depth cuts separate the segment of deteriorated concrete and allows room for its removal with minimal damage to surrounding materials.i a tm /afjpam t echnical m anual headquarters no.
