Description

Use of recycled materials to reduce track degradation due to impact loads. During the passage of trains, the load-bearing rock particles (ballast) on the track surface break due to high impact forces generated from rail and wheel imperfections. This project aims to study the benefits of an energy-absorbing layer of ballast mixed with recycled rubber granules together with sleepers made from recycled plastic and glass fibres. The enhanced track performance with reduced ballast breakage and vibration will be quantified based on large-scale laboratory testing and field trials, and simulated by innovative computer/digital modelling. The tangible outcomes will ensure more sustainable track design with improved safety, stability, and longevity, as well as significant reduction in the cost of maintenance and repairs..
