Project Background:
Railway sleepers, integral to rail stability and train safety, have traditionally been made of prestressed concrete. Despite its load-bearing strength, this material's susceptibility to cracking under dynamic loads is a concern for high-speed rail safety. Recognizing this challenge, the current study introduces the use of Engineered Cementitious Composite (ECC), a highly ductile material, aiming to diminish the incidence of cracks in railway sleepers and bolster their structural integrity and service performance.
Aims & Goals:
1. To enhance the crack resistance of concrete and improve its durability.
2. To increase the service life of prestressed railway sleepers and enhance the safety and stability of the track structure.
3. To be used in railway infrastructure located in complex and difficult terrains where maintenance is challenging, aiming to reduce maintenance requirements and improve robustness.
