Usage of reclaimed asphalt pavement in stone mastic asphalt
Coufalíková, Iva ; Katarína, Bačová (referee) ; Fišer,, Jiří (referee) ; Hýzl, Petr (advisor)
The dissertation deals with the possibilities of adding recycled asphalt pavement (RAP) to the stone mastic asphalt (SMA), which is increasingly being promoted due to its good resistance to permanent deformations and high traffic load. Thanks to the use of high-quality input materials in production, this is a valuable material source. The theoretical part describes composition of SMA mixture and problems of pavement recycling. The practical part deals with SMA 11S laboratory designs with RAP ratio of 0 to 50%. Based on these suggestions, a trial section with 17 variants was placed, which varied with the content and quality of the RAP and the used additives. All variants have been subjected to functional testing not only on mixtures but also on recovered binders. The results obtained during the dissertation were used to build a certified methodology named "Methodology of application RAP to Stone Mastic Asphalt." In conclusion, the results of the dissertation are summarized.

Evaluation of Tamping Method Trial Test Section
Tinka, Miloš ; Bombera, Ing Jan (referee) ; Svoboda, Richard (advisor)
The bachelor thesis deals with the evaluation of the influence of the modified tamping technology on the quality of the track geometry parameters. On the established test section, which is located on the doble-track line Břeclav - Přerov near the Rohatec village, a standard tamping technology was used on one track and the other modified. The adjustment consists in a larger number of tamping footprints, resulting in a larger reinforced surface of the sleeper bed beneath the sleeper. The aim of the thesis is to find out whether the modified technology will achieve a slower breakdown of the track geometry parameters and thus extend the time between the necessary repairs.
