Usage of recycled materials to asphalt mixtures
Zítka, Patrik ; Kašpar, Jiří (referee) ; Hýzl, Petr (advisor)
This thesis deals with the R-material use in asphalt mixtures. In the theoretical part, different kinds of flexible pavement recycling and ways of adding R-material into asphalt mixtures are discussed. The practical part deals with asphalt layers design and manufacture, specifically for binder course ACL 16+. R-material content in the blends is 0%, 20%, 25% and 30%. EVOTHERM MA3 rejuvenator is used as additive for softening of R-material. Various mixtures are compared based on tests - resistance to permanent deformation, resistance to the effects of water and low temperature properties.

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.
