PROBLEMS ASSOCIATED WITH RAILROAD FILLS AND SUPPORTS

An on-going investigation on rail support material is briefly reported. Triaxial static and repeated loading compression and extension tests on a dolomite ballast are reported and the significance to track design discussed. Model tests using a large scale rail track, ballast, sub-ballast and sand subgrade are reported. The significance to tie and track design of the results is briefly discussed. Further work is required but the results clearly indicate that fruitful conclusions should be forthcoming which would lead to reduced maintenance costs.
