The implementation of GFRP rebar in friction slab and crush barrier construction offers a corrosion-resistant and highly durable reinforcement solution. GFRP rebar exhibits superior resistance to electrochemical degradation mechanisms, eliminating the risk of rust and corrosion that plagues traditional steel reinforcement. This inherent property of GFRP rebar ensures structural integrity over an extended lifespan of 100 years or more, minimizing maintenance requirements and lifecycle costs. The non-corrosive nature of GFRP rebar is particularly advantageous in harsh environmental conditions, such as coastal regions or areas with de-icing salt exposure, where steel reinforcement is susceptible to accelerated corrosion. By incorporating GFRP rebar into friction slabs and crush barriers, transportation agencies can achieve enhanced durability, prolonged service life, and reduced maintenance expenditures, ultimately contributing to safer and more resilient infrastructure.
