New trends in the construction of flexible pavements
Palátová, Marcela ; Špaček, Petr (referee) ; Hýzl, Petr (advisor)
The aim of this thesis is to introduce innovations and trends in the construction of flexible pavement layers, which are used abroad. The paper is focused on some surfaces, which help to reduce noise pollution from traffic, and binders, which are based on natural ingredients called bioasphalt. It provides an information summary of increasing share of reclaimed asphalt in bituminous mixtures and introduces possible procedures that could lead to an increase in pavement life.

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.
