Considerations of the laboratory reference density for fine soil
Grmela, Jan ; Pácha, Petr (referee) ; Stehlík, Dušan (advisor)
The aim of this thesis is to describe the field of the soil compaction. The thesis introduces the particular test methods of the soil compaction, their principles and the implementation techniques. The practical part deals with the examination of a fine-grained sample in a laboratory condition. The compaction is achieved by various methods. In accordance with the compaction results, the soil is further examined for the Immediate Bearing Index (IBI) and California Bearing Ratio (CBR) after four day long saturation in water. The examination of the achieved results and finding the most suitable method for the fine-grained material is the outcome of the thesis.

The usage of the quarried aggregates to base layers of pavements
Borkesz, Michael ; Mondschein,, Petr (referee) ; Stehlík, Dušan (advisor)
The work deals with the possibilities of using fine crushed and quarried aggregate to base layers of roads. The introduction of the theoretical part explains the origin of this type of aggregate. There are also described the tests, which were used to verify the attributes and features of these mixtures and their use in cemented base layers of roads. In a brief way, the work also deals with foreign research and the possibilities that arise from it. In the practical part is then described the process of mixture preparing and laboratory tests carried out on them, the production of test specimens, load tests of these specimens and interpretation of the results. The conclusion summarizes the findings. Here are also discussed ways to apply them in practice.

The use of the waste aggregates for bound mixtures of pavements
Chloupek, Adam ; Zajíček, Jan (referee) ; Stehlík, Dušan (advisor)
The works deals with the possibilities of using non-standard fraction of fine crushed aggregate in route base layers. Goal of my thesis is research of using material from specific location. Theoretical part summarizes basic knowledge regarding bound mixtures and their normative requirements. Practical part of my thesis describes my various mixture design and following testing and determination of design properties by official and experimental tests. The conclusion summarizes the researched outputs and findings, which confirm the future possibilities of using this material in base layers.

Design of the bound mixtures to pavements
Hepner, Urban ; Pácha, Petr (referee) ; Stehlík, Dušan (advisor)
The bachelor thesis focuses on the monitoring of the impact of the shape on the tested bound mixture solid during the strength tests in an uniaxial stress. The theoretical part is devoted to the hydraulic binders bound mixtures, strength test in the uniaxial stress and furthemore discusses the foreign research concerning the topic of the strength ratio between a cylinder solid and a cubical solid. Practical part of the thesis describes the act of preparation of a mixture for the production of the test solids, laboratory tests provided on the prepared mixture, the production of the test solids and finally the following tests of the prepared solids strength in the uniaxial stress. All the results from the tests of the strenght in the uniaxial stress are in the end evaluated and compared to the foreign research.

Compactibility of the materials for subgrade
Kolbábek, Jiří ; Varaus, Michal (referee) ; Stehlík, Dušan (advisor)
This thesis is focused on differences between compaction of fine-grained and coarse-grained soils. It presents selected compaction methods and it describes their principles and implementation procedures. In the practical part is performed classification of both types of soils and then samples are compacted by three methods. The result of this work is to compare the effects of compaction on fine-grained and coarse-grained soil.
