Description
The paper presents results of tire/road noise and rolling resistance measurements performed on stone-matrix asphalt (SMA) that contains rubberized asphalt developed and produced by the company in Poland. Bituminous binder was modified with polymer and additive of crumb rubber. First observations of asphalt mixture with the new kind of modified bitumen used on the field section are presented. Rolling resistance of passenger car tires was measured by test trailer R2 Mk.2. Tire/road noise was measured by Tiresonic Mk.4 trailer using Close Proximity Method. Measurements were performed for 50 and 80 km/h and results obtained on test and reference sections covered with conventional SMA 11 were compared.
