Investigation into track stiffness, sleeper load and settlement using Rolling Load Rig experimental results (TM-SM-45)

This memorandum describes an attempt to find a sleeper/ballast stiffness curve that could be used for track modelling purposes. Test Data Track:- Concrete F23 sleepers with C.S.3 fastenings spaced 600 mm apart. Ballast:- Limestone from Ballidon Quarry. Grading:- 100% passing 38 mm (1½ in) 5%...
