BEHAVIOUR OF A PAVEMENT RESTING ON AN ANTI-VIBRATION MATTRESS AND SUBJECTED TO VIBRATORY MOVING LOADS TRAVELLING AT A CONSTANT SPEED

COMPORTEMENT D'UNE CHAUSSEE REPOSANT SUR UN MATELAS ANTIVIBRATILE ET SOUMISE A DES CHARGES ROULANTES VIBRATOIRES SE DEPLACANT A VITESSE CONSTANTE

The aim of the study described in this article is either to find theoretical justification for the experimental results obtained after the construction of existing pavements (Farnesina in Rome for example) or to show the influence of different factors on the amplitude of traffic vibrations. The calculations necessitated the use of simplifying hypotheses concerning the shape of the pavement, the nature of applied stresses and the laws governing the behaviour of materials (concrete and soil mainly). The study was conducted considering that the displacements of the pavement originate in an overall movement (infinitely rigid pavement) and in bending deformations. After considering the importance of those two applied stresses, the authors examine the effects of parameters such as the type of insulation, vehicle speed or wave length of the profile. Attention is drawn to the fact that the last two factors play a minimum role in the plotting of deformation curves. To characterize the efficiency of the insulation mattress, the average quadratic amplitude of deformation curves is used together with the forces transmitted to the foundations. These values are indeed indispensable for studying transmission phenomena in soil and for determining traffic stresses on a building. (TRRL)
