Steel-free bridge decks promise durable, cost-saving solution to corrosion problem.
A steel-free bridge deck was built in Tama County, Iowa to address corrosion issues caused by deicing salts. The deck relies on the internal arching action of the concrete slab for support, with shear studs and steel straps providing additional reinforcement. This innovative design reduces the need for steel reinforcement, leading to cost savings and increased durability. The bridge was successfully constructed and load tested, showing promising results for long-term maintenance and performance.
