Summary: This project aims to study the performance of a novel Synthetic Energy Absorbing Composite (SEAC) placed beneath the ballast to minimise degradation. The use of coal wash and steel slag blended with shredded recycled rubber as SEAC constituents is environmentally beneficial. The role of SEAC with respect to impact and cyclic loads will be assessed through extensive geotechnical laboratory and numerical analysis. The research outcomes based on the proposed energy considerations will lead to improved track design and analysis in view of stability, safety and operational efficiency.
