Abstract:

Prestressed concrete crossties are vital for railroad stability and safety, but frequently suffer premature failures—such as splitting cracks and corrosion—due to increasing heavy freight and high-speed rail demands. To address these vulnerabilities, this project employs a dual approach of 3D numerical simulation and experimental material development. The research identifies specific failure mechanisms while simultaneously optimizing a new fiber-reinforced “Engineered Cementitious Material” (ECM) designed to bridge cracks and enhance strength. By delivering a material formula with superior resistance to impact and environmental degradation, this study aims to significantly improve the structural integrity of crossties, ensuring safer, more durable railroad infrastructure with an extended service life.
