STRESSES IN THE RAILS, THE BALLAST AND IN THE FORMATION RESULTING FROM TRAFFIC LOADS. STRESSES IN THE FORMATION (RESULTS OF THE SECOND PHASE: INFLUENCE OF SLEEPER PARAMETERS AND THICKNESS OF CONSTRUCTION

The Objectives of Phase II of the program were to examine the influence of the following parameters on the longitudinal and lateral stress distribution between the subgrade and track structure under quasi static loading: 1) Ballast and Subgrade thickness; b) Crosstie flexural rigidity; c) Crosstie spacing; d) Crosstie packing conditions. Another objective was to check the validity of elastic theory for calculating the stress distribution in the track substructure.
