Coarse graded asphalt mixtures
Mucha, Ondřej ; Dašek, Ondřej (referee) ; Hýzl, Petr (advisor)
The bachelor’s thesis is focused on asphalt mixtures that contain coarser aggregates than currently allowed by technical regulations in the Czech Republic. The introductory part of the work describes the composition of asphalt mixtures, their division and use. Further deals with foreign experience with these types of asphalt mixtures and their use in the surrounding European countries and in the United States of America. The aim of this work is to obtain a theoretical overview of knowledge about coarse graded asphalt mixtures from foreign sources and research.

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.

Causes of runway surfacing failures at Karlovy Vary airport
Jůza, Petr ; Dašek, Ondřej ; Holcner, Petr
The modernized runway of Karlovy Vary airport was opened in the first half of 2006. However, significant failures of airport pavement occurred after one year of usage. During that time, these failures were massively developed. The risk of limitation (or in extreme cases, cancellation) of traffic on this runway occurred. That is why the Institute of Forensic Engineering of Brno University of Technology was asked by investor for working out the expert opinion in 2010. A total of 13 questions were asked. The main issue was identification of the causes of detected failures and determination of the responsibility of the individual litigants. This article is focused on this essential issue of referred opinion.
