Abstract:The behavior of the bridge barriers reinforced with GFRP bars is being investigated in collaboration with Ministry of Transportation of Quebec (MTQ). The test prototypes included four MTQ Type 311 barrier prototypes and two MTQ Type 210 barrier prototypes. For the MTQ Type 311 barrier prototypes, two of them were reinforced with GFRP bars and the other two were reinforced with steel bars. For the MTQ Type 210 barrier prototypes, one was reinforced with GFRP bars and the other one was reinforced with steel bars. The barrier prototypes consisted of a slab measured 2.5 × 3.0 m [98.4 × 118.1 in.] with a 225 mm [8.9 in.] thickness and a barrier of 2.6 m [106.1 in.] long. The barrier prototypes were tested under a monotonic increasing load up to failure. The test results revealed that the behavior of the GFRP-reinforced bridge barriers was comparable to that of the steel-reinforced ones.
