Project 3.05: Prevention of Stressed-Induced Failures of Prestressed Concrete Crossties ofthe Railroad Track Structure: Phase I

Prevention of Stressed-Induced Failures of Prestressed Concrete Crossties of the Railroad Track Structure: Phase I

Project 3.5

Project Summary

The problem we are trying to solve is to understand and mitigate premature failures of prestressed concrete crossties (PSCCs), which are an essential structural component of a railroad track structure. The objectives of the project are to identify the main mechanisms of splitting cracks upon de-tensioning prestressing wires with respect to various geometrical/mechanical parameters and to develop more durable bonding mechanism between concrete and prestressing wires using engineered cementitious materials (ECM).

Implementation of Research Outcomes:

While an output of a 12,000 psi compressive strength ECM has been
developed by using locally available resources including aggregates, the
research team is still investigating and implementation of research outcomes
will be reported upon completion of the research outputs.

Impacts and Benefits of Implementation:

This project is in its research phase. Impacts and benefits of the research will be reported after the implementation phase.
