Reduction of noise on road surfaces (wearing courses) in the Czech Republic

Popis výsledku v původním jazyce

Changes in acoustic characteristics of the road’s wearing courses during years of using have an immediate influence on the total noise level from the road traffic. According to the CNOSSOS-EU for the calculation of strategic noise maps, protection of the environment against traffic noise is very important. Long-term noise measurements by the CPX method are performed by only one company in the Czech Republic (CZE): Transport Research Centre (CDV). Low-noise wearing courses began to be used a few years ago (from mixture PA, through BBTM, to SMA NH (NH is the Czech abbreviation and marking for low-noise)). CDV cooperated on the elaboration of the technical specification TP 259 defining the rules for designing asphalt mixtures for noise reducing wearing courses and issued the certificated method for assessing their long-term noise performance, both of them were issued in 2017. Noise reduction increased slowly until documents were announced but rapidly increased after this because everyone had to start following the rules that had not been there before. Due to constantly changing low-noise mixtures, it is necessary to observe and evaluate acoustic characteristics of road surfaces during the lifetime of wearing courses and the whole roadway. Tyre/road noise very much depends on the asphalt mixture and condition of the wearing course. Low-noise and common asphalt mixtures are laid in some locations in the CZE right next to each other so that their behavior over time can be studied. Practical results measured in the CZE are described in this study. HABLOVIČOVÁ, Blanka, Vítězslav KŘIVÁNEK a Petra MARKOVÁ.
