Usage of fast-reacting SBS polymer in the production of asphalt mixtures
Dohnálek, Jakub ; Dašek, Ondřej (referee) ; Hýzl, Petr (advisor)
The subject of this diploma thesis is a research of bituminous binder modification by fast react-ing polymer SBS. The theoretical part covers an introduction to bituminous binders, their pro-duction, chemical and physical-mechanical properties. The identification of bituminous binders and their use in bituminous mixtures is briefly described. To conclude, current modification methods are described in detail and important modifiers are introduced. In the practical part, three applied tests (softening point, elastic recovery and penetration) are described in detail. The bituminous binders tested (20/30, 30/45, 70/100, PMB 25/55-55 and PMB 45/80-50) and the fast-reacting polymer SBS are introduced. Samples with two weight percentages of SBS, 7,5% and 10%, are produced. Two mixing times, 60 seconds and 600 seconds were used to mix the bituminous binder and SBS. In conclusion, the results are evaluated and commented. Further research suggestions regarding this field are recommended.
Vliv intenzity odkalení moštu na parametry vín révy vinné
Dohnálek, Jakub
The object of this bachelor thesis was the proces desedimentation of wine juice and subsequently it are methods of implementing. Further, the proces of clarification and preparation sused in this operation. The practical part was done experiment with a one species of wine of which have been formed four variants with diferent intensity of desedimentation. Subsequently was conducted running sulfidation. The wines were evaluated sensorially by one hundred scale and lines for their aromatic profiles. The conclusion was made statisticel evaluation and written finish with the results of individual variants.
Study of the southeast bypass of Uherský Brod
Dohnálek, Jakub ; Sabadáš, Petr (referee) ; Kosňovský, Michal (advisor)
Subject of this bachelor’s thesis is a study of southeast motorway bypass of the city Uherský Brod, a connection of roads II/490 and II/495. The study also deals with the possible relocation of road I/50 within the same area. Both existing roads are located in urban area. The reason for this study is an effort to reduce traffic intensity in the city and to complete the eastern motorway by-pass of the city. Three possible variants were described; one of them was chosen and described in more detail.
