ROLLING NOISE ON ASPHALT AND CONCRETE CARRIAGEWAYS

ROLLGERAEUSCHE AUF ASPHALT- UND BETONDECKEN

As a consequence of the sectional construction of the concrete carriageway on the south motorway in Carinthia (Austria), there was an opportunity to measure noise levels from different types of surfacing. In these comparative measurements the a-weighted noise levels were noted from the passing of two vehicles, a VW-Kombi and a Renault 16 car. The maintenance of a reference speed of 80 to 100 kph was controlled by a radar instrument. The measuring microphone was placed at a distance of 6 M from the longitudinal centre line of the vehicle at a height of 1.2 M. The noise levels for the following carriageway surfaces were measured: (1) concrete construction, built in 1970, very rough surface, maximum aggregate size 25 mm, (2) asphalt, aggregate 0 - 16 mm, 1973, (3) asphalt, aggregate 0 - 12 mm 1974, (4) gravel bitumen, not previously traversed, (5) concrete, new, not previously traversed. Compared to the rough concrete surface the following average noise level differences were observed: asphalt 0/16 -2.5 db(a); asphalt 0/12 -5 db(a); gravel bitumen -2.5 db(a); new concrete -1.5 db(a). It was established that in the case of the surfaces investigated it was not the binder material which had the greatest influence on the traffic noise but the structure of the aggregate. /TRRL/
