The reported work includes the experiment testing of glass fiber reinforced polymer (GFRP) and steel reinforced concrete bridge barriers. A total of four reinforced concrete barriers were prepared, including three GFRP reinforced barriers and one mild steel reinforced barrier, and cast on two concrete slabs. Impact testing was conducted using a cart with weight and a long straight sled system. The force, displacement, and strain data were measured. The results demonstrated that GFRP is fully capable of withstanding impact loads that could occur in real-world scenarios.
