STRESSES IN THE RAILS, THE BALLAST AND IN THE FORMATION RESULTING FROM TRAFFIC LOADS. STRESSES IN CONCRETE SLEEPERS

The results of study of the mechanical characteristics of concrete cross ties are analyzed. Some experiments werein the laboratory and other were carried out in track. The prestressed concrete cross ties of SNCF, BR and DB, as well as conventional cross ties are appraised. Laboratory tests determined the modulus of elasticity of concrete and studied tie deformations under specific loads. Track tests indicated the extent to which the real stresses were dispersed. Experiments permit definition of statistical ranges convenient for evolving an empirical solution to defining cross tie dimensions and to determining acceptance conditions for ties examined at a manufacturer's works.
