ABSTRACT
The article deals with properties of three different the most common used asphalt
mixtures, for pavement wearing course in term of noise pollution. The noise emissions
production is influenced (except for the tires, type and speed of vehicle) particularly by
pavement surface texture. The texture depends on asphalt mixture composition,
especially aggregate particle size distribution, maximum nominal aggregate size and
content and type of bitumen binder. The article presents results of research activities of authors dealing with three different asphalt mixtures – stone mastic asphalt (SMA), asphalt concrete (AC) and porous asphalt (PA). The texture characteristics of the listed asphalt mixtures were measured and evaluated by means of 3D scanner with high resolution. There were also evaluated physico mechanical characteristics of the asphalt mixtures, and noise pollutions measurements on selected road sections were performed as well.
