Abstract [en]

Previously great attention has been given for the quality of the track super structure to improve the overall performance of the railway. Frequent research on the track supporting materials shows a good result which improves the existing overall performance. Good ride quality with high speed, minimum initial construction capital, long life service and low maintenance cost are the issue on the railway technology. Ballast is one of the determinant parts of the railway structure which has great influence on the performance of the railway track.

The aim of this project is to assess the different aspects which affect the overall performance on the ballast structure, its material characterization, gradation, failure modes and modelling techniques. Quality based ballast material characteristics investigation and proper selection of ballast gradation with proper modelling methods will lead to an economical, minimum defect, minimum maintenance and replacement cost.
