Development of a precast concrete barrier wall system for bridge decks

In this article, the authors describe the development of a precast concrete barrier wall system to accelerate the replacement of deteriorated bridges. The barrier, which connects to the bridge deck slab using pretensioned threaded steel rods, is designed to expedite construction and minimize traffic disruption. In addition, it serves to improve work zone safety, quality and constructability while reducing life-cycle costs. Male-female vertical joints located between adjacent precast concrete barriers maintain barrier continuity under vehicle impact. The authors test five full-scale barrier models to examine capacity and crack patterns. The two models developed to represent the proposed precast concrete barrier system are loaded to induce failure at the barrier-deck slab junction and a control model represents a cast-in-place barrier. Results of the tests indicate that, with respect to the ultimate load-carrying capacity at the deck-slab barrier junction, the proposed precast concrete barrier functions as well as the cast-in-place barrier.
