OPTIMUM ADAPTION OF THE CONVENTIONAL TRACK TO FUTURE TRAFFIC. RHEOLOGICAL PROPERTIES OF THE TRACK
The laboratory tests carried out with a view to determining the dynamic modulus of elasticity of the ballast and described in the present report show that, from the point of view of vibratory phenomena, the real behaviour of the track can be simulated on the small test rig. The vibrations of the track have been analysed in the frequency range comprised between 20 and 90 Hz and it has been established that the use of sleepers of different types affects the modulus of elasticity and the position of the resonance peaks. It has thus been possible to show that heavy sleepers are better suited for high speeds.
