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.

该项目旨在研究放置在铁路道碴下方的新型合成能量吸收复合材料（SEAC）的性能，以最大限度地减少降解。使用洗煤和钢渣与碎再生橡胶混合作为 SEAC 成分对环境有益。 SEAC 在冲击和循环载荷方面的作用将通过广泛的岩土实验室和数值分析进行评估。基于所提出的能源考虑因素的研究成果将改进轨道设计和分析的稳定性、安全性和运行效率。
