Aslan™ 100 Glassfiber Rebars have been used in the
construction of several important concrete bridge structures
this spring season. The most significant of these projects
is the Floodway Bridge near Winnipeg Manitoba.
The bridge is a 16 span structure with
each span measuring approximately 15.5m x 43.5m. All concrete
elements above the girders are reinforced with Aslan 100
GFRP bars manufactured by Hughes Brothers, Inc. of Seward
Nebraska.
Implementation of the GFRP bars in the
bridge deck, barriers, abutments, deck drain and light standards
areas was designed per the Canadian Highway Bridge Design
Code which now includes provisions for the use of GFRP Reinforcing
bars.
Over 140.000 kg of Aslan 100 bars were used in this significant
bridge structure making it the largest bridge built to date
incorporating FRP non-metallic reinforcing. GFRP bars are
1/4th the weight of steel rebar. By using GFRP rebar, an
extended service life for the bridge structure is anticipated
due to the elimination of corrosion mechanisms in the steel
free structure.
Design guidelines, such as the Canadian
Highway Bridge Design Code, CSA S-806 building
Code and the ACI 440.1R-06 offer consensus standards for
reinforced concrete design using FRP bars. Test methods
such as ASTM D7205-06 and ACI 440.4R-03 describe tests used
to validate properties of the FRP bars.
The Floodway Bridge was designed by UMA engineering and
the contractor is MD Steel.
Aslan 600, GFRP dowels (non ferrous) are also available
for toll booths .
