OPTIMUM ADAPTATION OF THE CONVENTIONAL TRACK TO FUTURE TRAFFIC. STUDY OF THE CHANGE IN THE TRACK LEVEL AS A FUNCTION OF THE TRAFFIC AND OF THE TRACK COMPONENTS (FIRST RESULTS OF LABORATORY AND SITE TESTS)

The report deals with the change in the longitudinal level of conventional tracks under the effect of operating loads. Tests have been carried out in the laboratory and on actual sites on differently equipped tracks, with a view to defining the influence of the various track component parameters. The discovered evolution law of defects has shown that the reduction in sleeper spacing and of crib and shoulder consolidation exert a rather clear influence. It has also become apparent that the quality of the maintenance operations exerts a very large influence. These findings should however be treated with caution. The influence of the inertia of the rail, the thickness of the rail pads, the types of sleepers and the conditions of the formation and of the ballast, will be accurately defined later.
