Possibilities of Rolling Noise Reduction by Application of Acoustic Asphalt Mixtures

Popis výsledku v původním jazyce

Traffic noise is a constant problem especially in dense developed regions and urban areas. Road administrators and road owners fight with it every day. Rolling noise created at the contact of a tyre and the pavement surface dominates at speeds of 40 km/hand higher depending on vehicle type. It can be reduced by using special acoustic asphalt mixes. This paper presents a brief overview of technologies which are mainly derived from the German and French experience. First results from the experimental design of these mixes are presented further. These mixes and used binders were prepared and optimized at the Department of Road Structures of the Faculty of Civil Engineering, CTU in Prague during first two years. It also gives a description of the laboratory measurement of sound absorption of asphalt mixtures using the impedance tube. The objective of this measurement on laboratory samples is its real ability of predicting rolling noise reduction.
