Design of asphalt concrete mixture and determinantion of the resistance against permanent deformation
Němec, Jan ; Matoušek, David (referee) ; Varaus, Michal (advisor)
This bachelor thesis deals with the problem regarding asphalt concrete mixtures, concretely ACO 11+. This type of mixture has low resistance to permanent deformation (rutting) while high temperatures are present. The binder and aggregate tests regarding physical and mechanical properties were carried out. Subsequently the new mixture was designed on the basis of stricter requirement for grading envelope and air void content. The design mixture was tested for resistance to permanent deformation. From the obtained results the change in the national annex of the standard ČSN EN 13108-1 is considered in terms of change in testing temperature for some kinds of binders. The same tests were conducted in others asphalt laboratories in the Czech Republic to ensure the maximum comparability.

Binders for flexible pavements
Pěnčík, Michal ; Čiháčková, Pavlína (referee) ; Hýzl, Petr (advisor)
The Bachelor`s thesis is focused on binders, which are used in flexible pavements. Firstly, we offer the reader description of different types of bitumen binders, which could be found in nature, and binders produced from petroleum through the process of distillation and further processing. Later on, we focus on the issue of testing these binders. The last part of the work deals with alternative types of binders which could potentially replace traditional bitumen binders.

Adhesion of bituminous binders to aggregate
Vlk, Petr ; Hýzl, Petr (referee) ; Varaus, Michal (advisor)
In 2005 the revised European standard 12697-11:2005 [1] was introduced offering a choice of three different methods. The static method described in part B has some similarities with the replaced Swiss standard for the determination of the affinity between bitumen and aggregates [2] and Czech standard for adhesions of asfalt binder to aggregates ČSN 73 6161 [3]. The result of this study is to compare the static method described in the [3] and a draft changes by Swiss research project [4] with the current revision of the European Standard 12697-11: 2005.

Design and evaluation of asphalt rubber mixture
Hotař, Petr ; Dašek, Ondřej (referee) ; Kudrna, Jan (advisor)
The aim of bachelor thesis is to design the asphalt concrete for very thin layers using asphalt rubber and to perform laboratory tests according to ČSN EN 13108-2 and TP 148. The work is based on the literature review and respects properties of asphalt rubber. The expected properties of asphalt concretes for very thin layers are summarized and evaluated.

Marketing Strategy of a Chosen Product on The Example of DuPont
Wojnar, Michal ; Zamykalová, Miroslava (advisor) ; Vacín, Otakar (referee)
The bachelor thesis "Marketing Strategy of a Chosen Product on The Example of DuPont" is aimed at analyzing the marketing strategy and marketing mix of the Elvaloy material which is used in paving segment. The main applied methodology is called situation analysis through which the author compares individual key markets, reviews internal and external conditions of the company and studies the competition. The main objective of the thesis is also to present diminishing differences between industrial and consumer marketing and creation of new hybrid marketing concepts. As a main motive force of this step change is in this case considered globalization and its associated effects.
