Road noise is an important problem in environment protection and transportation network development. In
addition to vehicle engine and aerodynamic, it is also related to tire/pavement interaction, especially once the
vehicle speed exceeds 50 km·h–1. Application of special material and technological solutions can help to limit
that noise. In order to meet this goal, pavement surface layers are constructed with asphalt mixtures such as
stone mastic asphalt (SMA) with fine gradation or with higher air voids content (SMA-LA and BBTM), porous
asphalt (PA) and mixes with asphalt rubber. Recently various road sections in Poland were constructed
with asphalt technologies lowering tire/pavement noise.
This paper presents results of survey dealing with intensity of noise reducing pavements application in Poland
in roads operated by General Directorate for National Roads and Motorways and administrators of
voivodeship roads.
