Concrete sleepers have become widely and successfully accepted for railway sleepers. However, this type of sleepers is vulnerable to rail-seat deterioration and concrete cracking resulting in the corrosion of steel reinforcements, thereby reducing its service life. Similarly, the steel reinforcement in concrete sleepers affects the train signalling systems causing costly operation delays and accidents. These issues are anticipated to be addressed by using FRP bars due to its non-corrosive and electromagnetic neutral properties. Thus, the aim of this project is to develop and investigate the structural performance of new concrete sleeper technologies reinforced with GFRP bars. It involves experimental and analytical studies to come up with a sleeper technology with optimum section and material usage, and assured structural performance.
