Huval and Associates offered to revitalize the surface of a suspension bridge across the Mississippi River in the parish of St. Charles, Louisiana, with a composite system based on Kevlar and fiber-reinforced plastic.
The Hale Boggs Memorial Bridge connects a town of Destrehan on the east bank to Luling on the west bank. This bridge is 10,699-foot-long, and because of the design features it is more mobile than bridges on the supporting piers. The Louisiana Department of Transportation and Development had to find a solution that provided the most longevity of the renovated bridge surface.
According to Vectorply’s South/Central Region Sales Manager Doug Lachapelle, suspension bridges constantly move, so a typical concrete and steel reinforced surface does not do well by itself and will eventually end up cracking. For this task, Huval and Associates decided to use a composite system utilizing Vectorply’s Kevlar/E-glass hybrid material and a highly adhesive and flexible epoxy resin.
The Hale Boggs Memorial Bridge is the latest infrastructure project involving Vectorply to show the value composites provide in revitalization and repair of structures.
