Use of R-material in asphalt mixtures with highly modified binder (HiMA)
Christ, Roman ; Dašek, Ondřej (referee) ; Hýzl, Petr (advisor)
The subject of this diploma thesis is paid attention to the influence of different dosing of R-material containing unmodified asphalt on the properties of asphalt concrete for abrasive layers (AC011 +) bonded with polymer highly modified asphalt (binder type HiMA). The properties of asphalt mixtures will be evaluated by means of the stiffness modulus test and the test of low-temperature properties by a uniaxial tensile test.

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.

Use of special binders for recycling of asphalt mixtures at mixing plants
Pěch, Pavel ; Špaček, Petr (referee) ; Varaus, Michal (advisor)
The thesis deals with the matter of usage of special asphalt binders for production of asphalt mixtures containing recycled materials in asphalt plant. For comparison analysis of characteristics of special binder used in roads is necessary to compose different mixtures of asphalt – one with binder containing R-materials, and another benchmark mixture with binder used in common mixtures without recycled materials. Investigation of features of mixtures with different binders is carried out by selected performance tests of asphalt mixtures. Evaluation and comparison of the results is described in the final section of the thesis.

Influence of aging on selected properties of asphalt binders
Rimel, Jindřich ; Dašek, Ondřej (referee) ; Hýzl, Petr (advisor)
In this bachelor’s thesis, the properties of four asphalt binders with different degree of modification are compared. The influence of aging on their properties is examined. In the theoretical part, the types of aging, their impact on binders, basic laboratory methods of aging and the details of performed tests are explained. In the practical part, the results of tests are evaluated and the change of properties before and after aging are compared.

PmB - Polymer modified bitumens
Venclíková, Michaela ; Dašek, Ondřej (referee) ; Hýzl, Petr (advisor)
In this bachelor thesis, there are described modified bitumens. The issue of modified bitumens will be explained in the theoretical part. In the practical part, it will be prepared set of modified bituminous binders with different degree of modification. Basic empirical testing and functional testing will be determined. The aim of thesis is to find the optimal source of unmodified bitumen for modification.
