E. and Fontana, J. and Steinberg, M.}, abstractNote = {Research was done in three general areas: material properties of polymer-impregnated concrete, repair of deteriorated and delaminated bridge decks, and polymer impregnation of new deck surfaces.
PennDOT patching materials are discussed, along with the ASTM tests that determine basic material properties of the chosen patch materials. 1.4.1 Bridge Deck Deterioration To determine the best way to repair deterioration in bridge decks, one must first understand the various mechanisms by which deterioration can take place. The following
Long-life Pavements - European & American Perspectives. The ambition for building long-life pavements (LLPs) of roads is obvious in every country due to the ever-increasing traffic demand and funding constraints. LLP is an efficient way to reach the aimed goals of lower whole life cost and lower user costs (traffic operation cost, time delay ...

Evaluation of Patching Materials and Placement Techniques for Rigid Pavements and Bridge Decks Final Report Number WPI 0510861. Florida Department of Transportation, Tallahassee, Florida.
Bridge decks and parking structure slabs, as well as other interior slabs may be coated effectively after cracks are treated by injecting with epoxy or by routing and sealing. Materials such as urethanes, epoxies, polyesters, and acrylics have been applied in thickness of 0.04 to 2.0 in. (1 to 50 mm), depending on the material and purpose of ...
Thin-bonded patching applies to surface scaling and spalling, spalling at edges and joints, and other surface deterioration that does not extend below the pavement mesh. Thin-bonded patching also is applicable for similar deterioration on bridge decks and especially for spalling associated with insufficient cover over the top mat of reinforcing.
evaluation of patching materials and placement techniques for rigid pavements and bridge decks The objective of this research study was to evaluate the performance of various types of advanced materials available on the market for use in partial depth repairs of …
materials are currently being developed to improve its low-temperature performance and moisture susceptibility. OBJECTIVES The goals of this project were to explore the advantages, challenges, and feasibility of using a hybrid, semi-flexible, semi-rigid concrete for highway pavements, bridge decks, and overlays. Specifically, the objectives
Although it has never been used as an interlayers, previous studies showed that ECC could be used to construct overlays to repair deteriorated rigid pavement or bridge decks, which successfully ...

The Structure Construction Bridge Deck Construction Manual is intended to serve as a guide and a reference source for Bridge Engineers and others involved in field engineering and bridge decks under construction. As this manual is intended solely as guidance material, contract documents should always prevail in case of conflicts.

Coordination early in the design process with DNR regarding removal techniques for the existing structure (if applicable), and new structure placement and type is very important. The status of any agreements with the DNR, which affect the structure, should be noted under additional information on the Structure Survey Report.

Waterproofing and Surfacing of Concrete Bridge Decks April 2019 Page 3 2. Scope 2.1 General This Standard specifies the requirements for waterproofing and surfacing concrete bridge decks and shall apply generally to new works and where appropriate to the maintenance and repair of existing works.
Among promising methods of repair which have been tried on bridge decks is that of overlaying the old deck with a relatively thin layer of concrete, (l.=§,). Portland cement concrete overlays are attractive for this purpose because the material is durable, relatively inexpensive, and easy to place.
Products suitable for consid- eration by the program are cementitious, latex-modified, poly- mer resin, magnesium phosphate, and other materials expressly designed for patching PCC pavements and bridge decks. An extensive suite of laboratory-based testing is undertaken for each material. Field test sites are also monitored for two years (58).
- Bridge decks with existing spalls and/or delaminations greater than 5% of the deck area are typically not good candidates for polymeric overlays. Excessive, wide cracking may also be an indication that a rigid overlay is a better treatment, if feasible. The anticipated amount of …
