Prevention of Stress-Induced Failures of Prestressed Concrete Crossties of the Railroad Track Structure (3.5)

The problem the research team is 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 horizontal 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.
