Cumulative effects of cracking in monoblock multipurpose precast concrete sleepers on railway tracks

This work addresses the phenomenon of cracking in multipurpose precast monoblock concrete sleepers by examining the entire process from fabrication to final installation on railway tracks. This includes stages such as manufacturing, stockpiling, track installation for rail neutralization, and eventu...
