Low - noise pavements
Mojžíš, Martin ; Zdřálek, Petr (referee) ; Hýzl, Petr (advisor)
Master´s thesis is interested in the problems of low-noise road surfaces. The theoretical part describes noise, sources of noise, the low-noise road surfaces and the practical part describes two proposals of low-noise stone mastic asphalt SMA 8 LA.

Design of low-noise asphalt mixtures
Řehulka, Martin ; Koudelka, Tomáš (referee) ; Varaus, Michal (advisor)
The Master’s thesis is focused on low-noise asphalt mixtures in general, namely asphalt concrete for very thin layers with low noise (BBTM 8 NH) and stone mastic asphalt with low noise (SMA 8 NH). The first half of the thesis describes basic types of asphalt mixtures with low noise, requirements for raw materials (aggregates and asphalt), noise emissions and their measurement methods. The second part deals the design of BBTM 8 NH and SMA 8 NH so that they have the same voids. Subsequently, their parameters were tested. Acoustic absorption, resistence against permanent deformation and stiffness. Test methods are described and evaluated.

Low noise pavement surfaces
Zítka, Patrik ; Dašek, Ondřej (referee) ; Hýzl, Petr (advisor)
This bachelor´s thesis focuses on the use of low-noise road surfaces, due to a constant increase of traffic noise nowadays. Within this work different types of roadways are analyzed and their advantages and disadvantages are shown. Additionally, the basic measuring methods of the traffic noise are described and summarized. Finally the procedures and results of the measurements on noise emissions on low-noise surface VIAPHONE® are discussed.
