Hviskeasfalt, sådan som vores flamske venner kalder det, eller ZOAB, meget åben asfaltbeton, som vi kalder det i Nederlandene, er 20 decibel støjsvagere end en vej med brosten.
The noise level from'fluisterasfalt '[silent asphalt], as it is termed by our Flemish friends, or'ZOAB, zeer open asfaltbeton' [very open asphalt concrete], as we like to refer to it in the Netherlands, is probably 20 decibels lower than that from cobblestone roads.
