Noise Reducing Techniques on Existing Continuously Reinforced Concrete Pavements on Belgian Motorways

Paper by CAESTECKER HELEVEN from ISCR 7th 1994 Vienna Austria

Most of the Belgian Motorways, with a concrete pavement, have a deeply grooved concrete surface. Although those wearing courses have a very good skid resistance, there is a great concern about the noise pollution. Not only noise barriers and the porous asphalt overlay, but recently also the grinding are an economical solution to the noise problem. The report gives the first results of the technique applied on the Belgian Motorways. These results proved to be very satisfactory, and the technique will be applied on many sites.
