Rheological properties of asphalt binders
Pěnčík, Michal ; Mondschein,, Petr (referee) ; Hýzl, Petr (advisor)
The Diploma thesis is focused on rheological properties of bituminous binders and mixtures. Above all, it describes the changes of these properties of samples of bituminous binders and mixtures. Those were brought by the process of laboratory aging, since it simulates the changes occurring in the in the real-life conditions. The theoretical part depicts the field of rheology and methods utilized for simulating the ageing of binders and mixtures. The practical part describes the process of preparation of samples and its testing. Firstly, the ageing of bituminous mixture by the means of BSA method (Braunschweiger Alterung) took place, which was followed by preparing the solids for testing the modulus of stiffness and main testing. The rest of the mixture was used for extracting the binder. Tests with the binder were focused on the usage of dynamic shear rheometer (complex shear modulus, dynamic viscosity). The last part of the work is dedicated to the comparison of the outcomes of testing.

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.
