Stone mastic asphalts with recycled materials - bituminous binders properties
Dzurková, Veronika ; Coufalíková, Iva (referee) ; Hýzl, Petr (advisor)
The bachelor thesis is focused on the issue of adding R-material to stone mastic asphalt mixtures (SMA). The material was obtained from a plant that put the mixture in the test section on the road II/227. The theoretical part describes the problems of recycling of asphalt roads, bituminal binder theory and problems associated with the addition of R-material to hot asphalt mixtures. Bituminal binders from mixtures with different percentages of R-material were extracted in the practical part. Empirical and functional tests were performed on these binders. The aim of the thesis is to determine the influence of the presence of R-material on SMA asphalt mixture in terms of properties of asphalt binder.

Dosage of rejuvenating agents to asphalt mixture with high content of RAP
Čumíčková, Markéta ; Coufalíková, Iva (referee) ; Dašek, Ondřej (advisor)
The diploma thesis is focused on the appropriate dosage of rejuvenating agents in asphalt mixtures with high content of RAP. The empirical and functional laboratory tests are described in the theoretical part. The practical part deals with the estimation of the optimal amount of rejuvenating agents by means of laboratory tests so that the rheological properties of the degraded asphalt binder can be restored by suitable dosing into the RAP. As part of the TAČR ZÉTA project, an experimental section of asphalt mixture containing 50 % of the RAP and an appropriate amount of the rejuvenating agents was created. The aim of the thesis is to find an optimal dosage of the rejuvenating agents in the samples of the RAP and laboratory aged asphalt binder of gradation 50/70, to determine the effectiveness of selected rejuvenating agents and to monitor changes in the parameters of the experimental section during the period of time.
