Asphalt mixtures with the use of higher amount of RAP
Mucha, Bohumír ; Matoušek, David (referee) ; Varaus, Michal (advisor)
At the beginning of the Master’s thesis the asphalt mixture of the type asphalt concrete and its basic properties are described. The main point of this work is to compare the functional properties of asphalt mixtures with the addition of higher amount of RAP and various rejuvenators used in the experimental section. From individual samples of asphalt mixtures taken during the laying, the control tests were carried out and the process of permanent deformation with the wheel tracking test was monitored. After that, using functional tests the properties of asphalt mixtures with conventional modified and unmodified asphalt bitumen enriched with the addition of declaring similar properties were compared.

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.

Usage of of common reclaimed asphalt in asphalt mixtures
Přívara, Jakub ; Coufalíková, Iva (referee) ; Dašek, Ondřej (advisor)
The bachelor thesis is focused on adding of RAP (reclaimed asphalt pavement) to the wearing asphalt courses flexible pavements. Specifically it is SMA 11S asphalt mixture. The theoretical part describes issues of ecology and recycling. The practical part deals with bitumen recovery from SMA mixtures with different added ratios of RAP and assessment of basic empirical and functional tests on the bituminous binder. The verification of properities of modified bituminous binder used in this quality SMA mixtures is also introduced.
