Résumé / Abstract
Pavement discontinuities in urban areas contribute to local noise emission, which is related to the type of discontinuity (pavement equipments or surface distresses) and their level of severity. After evaluation of the different discontinuities that can be encountered on the urban road network, three different measuring procedures are detailed in order to quantify an acoustic indicator (Delta L) (Disc) representative of the discontinuities effects. After validation of the various experimental techniques, and from results based on large experimental campaigns in different urban situations, a methodology to fill yp two "Severity Level" matrixes for distresses and pavement equipements respectively, is detailed. Those matrixes will finally be used to propose a methodology, which will allow identifying the possibility to predict the evolution of the discontinuities from an acoustic technique in association to a statistical analysis. Finally, some first preliminary experimental results obtained through an adapted CPX procedure developed in LCPC-France show the possibility to predict the evolution of the discontinuities from an acoustic technique in association to a statistical analysis., RAPPORT D'ETAPE
