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.

Improvement of soils for pavement subgrade
Šefránková, Radka ; Pácha, Petr (referee) ; Stehlík, Dušan (advisor)
The bachelor thesis deals with improvement of unsuitable soils for pavement subgrade. The theoretical part describes technologies of modification and materials employed for improving soils in our country and abroad. The main target of the practical part is observing bearing capacity of unimproved and improved soils and comparing the results.

The frost susceptibility of soils and materials for subgrade of pavements
Puda, Adam ; Pácha, Petr (referee) ; Stehlík, Dušan (advisor)
The bachelor thesis deals with the theoretical part of the deformation caused by frost action, but primarily frost heave, their gradual development and factors affecting their final formation. Furthermore, different ways of measuring the frost susceptibility in the Czech Republic and their comparison. Introduction to the different methods of measuring frost susceptibility in selected countries within the European Union. The practical part is focused on the process of frost heave samples with and without thermal insulation material.

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.

California bearing ratio CBR - dynamic test
Cvečka, Tomáš ; Pácha, Petr (referee) ; Stehlík, Dušan (advisor)
The work is devoted to the use of dynamic load test in road construction. The theoretical part deals with the description of the test with using classical CBR test with dynamically acting load. The practical part is devoted to the preparation of the soil sample for the dynamic test and following evaluation of the classical static and experimental dynamic method tested on two soil samples. The aim of the work is to find out the correlation relationship of these two tests as well as to verify the relevance of the used dynamic method.
