A precast slab track partially reinforced with GFRP rebars

The precast slab track system partially reinforced with glass fiber reinforced polymer (GFRP) rebars in transverse direction for loss mitigation of track circuit current by reducing magnetic coupling between rail and steel reinforcements is investigated. It is verified with the electric analysis that the GFRP rebars work for mitigating the reduced current strength produced by electro-magnetic induction. Both three dimensional finite element method and flexural experiments are used to study mechanical behavior of proposed slab track.
