A study of upsetting tests
Chludil, Petr ; Šlais, Miroslav (referee) ; Podaný, Kamil (advisor)
Upsetting, or pressure tests are in an engineering practice used for determining the effect of the pressure load on material properties. They determine the values of deformation resistance and formability of tested materials. The usability of upsetting tests is even expanded with different kinds of execution, shapes of test samples and kinds of used test machines. Upsetting tests are then one of the most important and most variable kinds of tests that are used for the examination of mechanical properties of materials in an engineering practice.

Influence of the sample preparation on the stiffness of asphalt mixtures
Pěch, Pavel ; Hýzl,, Petr (referee) ; Varaus, Michal (advisor)
The Bachelor thesis deals with influence of the preparation of probationary bodies to determine of modulus of stiffness. Bodies in the form trapezoid are prepared in two different ways - with trimming and without trimming of all surfaces of the upper and lower party. This way prepared bodies are tested and is determined two-point test for modulus of stiffness. The results of tests are mutually compared.

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.
