Benefits of Using FRP for Pedestrian Bridge Decks. Compared to more traditional decking materials, FRP is superior on many levels. Our FRP panels offer the following benefits: Lightweight Construction: An FRP deck weighs at most 20% of a comparable reinforced-concrete design. In addition to reducing strain on the bridge’s structure, this. bridge projects that use FRP decks. Typically the costs of these systems far exceed those of a reinforced concrete deck; therefore the development of a more cost-effective FRP bridge deck system is warranted. This research examines the use of pultruded, off the shelf components as a lower cost alternative FRP bridge deck Size: KB.

Consequently, a set of tests were conducted on four wearing surface products in order to select the material with the best performance with respect to service conditions on an FRP deck. The products were evaluated for tensile strength, failure strain, bond strength, and abrasion resistance.
For FRP decks, a wearing surface also serves as a cover to protect the slick and soft-top surface of the panels. Several conventional wearing surfaces have been used on FRP bridge decks, e.g. polymer modified concrete, polymer concrete, and Size: KB.
Wearing surface materials are needed on bridge decks for skid and wear resistance and to withstand the daily traffic loads during the service life of the bridge. For FRP decks, a wearing surface also serves as a cover to protect the slick and soft top surface of the : Prapun Wattanadechachan.

Evaluation of High Performance Pavement and Bridge Deck Wearing Surface Repair Materials This project provided for a laboratory and field testing of several high performance repair materials for pavements and concrete bridge by: 1.
Fibre reinforced polymer (FRP) bridge decks have become an interesting alternative and they have attracted increasing attention for applications in the refurbishment of existing bridges and the construction of new bridges.
The benefits brought by lightweight, high-strength FRP materials to these applications are well by: Performance Evaluation –FRP Deck Bridges •Dynamic load allowance factors for the two bridges are within design code limits.
The limits are exceeded for Laurel Lick Bridge. •Traffic induced bridge vibrations are clearly perceptible in the two FRPFile Size: 2MB. Various concerns have been noted with existing FRP bridge decks including leakage of joints, delamination of the wearing surface and fiber reinforced polymer, inadequate stiffness, and a lack of.
was made to use a fiberglass reinforced polymer (FRP) composite material for the bridge deck. The selected composite material was “DuraSpan TM” from Martin Marietta Composites. This report will cover the planning and design of the bridge, construction of the bridge with the FRP deck File Size: 1MB.
After an introductory overview and an assessment of the characteristics of bonds between composites and quasi-brittle structures, Advanced Composites in Bridge Construction and Repair reviews the use of advanced composites in the design and construction of bridges, including damage identification and the use of large rupture strain fiber-reinforced polymer (FRP) composites.
The second part of the book presents key applications of FRP composites in bridge construction. with steel. The FRP decking systems are usually bonded with polymer concrete as wearing surface in the field for proper traction and rideability. However, cracking of polymer concrete wearing surface mostly along the length of a joint connecting FRP modules in the field has been noted in several FRP bridge deck systems.
The other option is to have the material supplier install their product in Guardians shop. Example of RPM Matacryl which is a manufacturer of Bridge Deck Wearing Surfaces were lightweight thin applied is desirable: Example of micro slurry system, chosen by the Engineer of Record.

Inthe Fiber-Reinforced Polymer Trail Bridge Project at the Missoula Technology and Development Center (MTDC) began evaluating the feasibility of FRP materials for trail bridges used by the U.S.
Department of. Another is cosmetic. The bridge deck’s most visible feature is well what you see. Users want the bridge deck’s surface to look great, last a long time and require minimal maintenance.
Owners want a product that won’t break the bank. We apply a non-slip wear overlay to the top surface of our pedestrian decks during the production process. For the design of the FRP Deck, three limit states are considered: (1) Service, (2) Strength, and (3) Fatigue. The service limit state prevents excessive local deck deflection that can cause premature deterioration of the wearing surface and affect the performance of joints.
A standard AASHTO HS design truck load without. In contrast to the 4-inch/cm layer of asphalt or concrete used on typical bridge decks, a mere inch/mm (or less) of wear layer is used, yet it offers longer service life because the wear surface material is more flexible than steel or conventional concrete.
The deck panels were prefabricated, including the wear surface, curbs and expansion joints. This reduced on-site construction time. More importantly, the FRP bridge deck is 80 percent lighter than a concrete deck, making it faster to lift, move and place by crane.
Composite Advantage supplied 57 prefabricated deck panels measuring x feet. Local top surface strains and displacements of the cellular FRP deck are found to be higher with proposed loading profile compared to those for the conventional uniformly distributed loading. Parametric studies on the deck geometry show that the global displacement criterion used for characterizing bridge deck is inadequate for a cellular FRP.
One of the primary functions of a wearing surface is to protect the bridge deck. The surface material and thickness should be based on the expected weight and density of traffic. A thicker or more abrasion-resistant surface is required for heavy truck traffic or tire chain use.
Partial wearing sur faces offer the least protection and frequently result in deck wear from vehicle off-tracking (Figure ).File Size: KB. mize cracking of the wearing surface in the negative moment region over girders. • The case study bridge, CR E. over Sugar Creek, was studied for use of a fiber reinforced polymer (FRP) deck for bridge rehabilitation and deck widen-ing.
The 2% cross slope on the deck was to be built into the FRP deck installation; the crown connection.
