QUALITY OF DIFFERENT PAVEMENT SURFACINGS AS REGARDS ROLLING NOISE

QUALITE DES DIFFERENTS REVETEMENTS DE CHAUSSEE A L'EGARD DU BRUIT DE ROULEMENT

With the decrease in engine and exhaust noise over the last ten years, noise due to tyre/road contact has become more important. It is particularly a problem on motorways and uncongested urban roads especially at night. The source of tyre/road noise is examined including shock noises, air pumping and the 'slip and stick' phenomenon. A description is then given of a study carried out in strasbourg which aimed to characterise tyre/road contact noise by identifying the features of the pavement surface which influence noise emission and recording the noise emitted by particular types of vehicle. Five different surfaces were subjected to trials: 0-12mm asphaltic concrete, 0-2mm sand 4cm thick, 15% void pervious macadam 4cm thick, one-layer surface dressing and nancy carpet with 6-10mm chippings. Noise was recorded from 15 different vehicle/tyre configuration passing at 5 speeds. Characteristics of the pavement were also recorded including evenness, sand patch depth, macrotexture, drainage capacity, transverse and longitudinal friction coefficients, acoustic and mechanical impedance. Results are presented graphically and the standard method devised described. The advantages of pervious macadam are listed and amounts by which noise may be reduced in various situations suggested. This paper was originally published in French at the conference "routes et circulation routiere pour l'an 2000", Berlin, September 1988.
