Problem Today, 40% of the world’s freight cargo is transported via rail making the structural integrity of railways and their substructures essential. Weak or compromised rail sub- structure can lead to track instability, transit slowdowns, train derailments, ballast fouling, and differential track deflection. Maintenance activities to prevent these outcomes are very important and commonplace for railroad substructure systems, but they come at a cost. Track maintenance in areas with weak subgrades is especially expensive because ballast replacement, tamping, and track realignment are often required. URETEK teamed with the University of Wisconsin - Madison to determine if URETEK Deep Injection ® (UDI) could offer a cost-effective way to improve weak subgrade and in turn increase
