Rolling resistance and tyre/road noise on rubberised asphalt pavement in Poland

The paper presents results of tyre/road noise and rolling resistance measurements performed on stone mastics asphalt (SMA) that contains rubberised asphalt, developed and produced by a refinery in Poland. Bituminous binder was modified with polymer and addition of crumb rubber. The first observations of asphalt mixture with the new kind of modified bitumen used on the field section are presented. Rolling resistance of passenger car tyres was measured by test trailer R2Mk.2. Tyre/road noise was measured by a Tiresonic Mk.4 trailer using the close proximity method. Measurements were performed for 50 and 80 km/h and the results obtained on test and reference sections covered with conventional SMA 11 were compared.
