This project aims to study the performance of a novel synthetic energy absorbing composite (SEAC) placed beneath the railway 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.

该项目旨在研究一种新型合成能量吸收复合材料（SEAC）的性能，该材料放置在铁路道碴下方，以最大限度地减少退化。使用洗煤和钢渣与切碎的再生橡胶混合作为SEAC成分是环境有益的。将通过广泛的岩土实验室和数值分析评估SEAC在冲击和循环荷载方面的作用。基于拟议的能源考虑的研究成果将导致改善轨道设计和分析的稳定性，安全性和运营效率。
