Corrosion of steel reinforcement due to environmental effects is a major cause of deterioration problems in bridge barriers. Glass fibre reinforced polymers (GFRP), not only addresses this durability problem but also provides exceptionally high tensile strength, and Young’s modulus. The special ribbed surface profile of the studied GFRP bars and end anchorage heads ensure optimal bond between concrete and the bar and eliminate the use of custom made bar bends. A recent design work conducted at Ryerson University on PL-3 bridge barrier proposed the use of 16 mm and 12 mm diameter GFRP bars as vertical reinforcement in the barrier front and back faces, respectively, with 12 mm diameter GFRP bars as horizontal reinforcement in the barrier wall, all at 300 mm spacing. The connection between the deck slab and the barrier wall utilized the GFRP headed end bars for proper anchorage. This paper summarizes the procedure and the results of a recent vehicle crash test conducted on the developed barrier. The crash test was performed in accordance with MASH Test Level 5 (TL-5), which involves the 36000V tractor trailer impacting the barrier at a nominal speed and angle of 80 km/h and 15º degrees, respectively. Crash test results showed that the barrier contained and redirected the vehicle. The vehicle did not penetrate, underride or override the parapet. No detached elements, fragments, or other debris from the barrier were present to penetrate or show potential for penetrating the occupant compartment, or to present undue hazard to others in the area. No occupant compartment deformation occurred. The test vehicle remained upright during and after the collision event.
