Asphalt concrete for very thin layers
Kubánek, Ondřej ; Frýbort, David (referee) ; Hýzl, Petr (advisor)
The aim of bachelor thesis is to gain experience with the design mixtures of asphalt concrete for very thin layers. Familiarizing with the properties of these mixtures, as porosity, water resistance and resistance to permanent deformation. Comparing detected parameters with the requirements of standard EN 13108-2 and its National Annex.

Usage of thin wearing courses with highly polymer modified bitumen
Renza, Jaroslav ; Rous, Vojtěch (referee) ; Dašek, Ondřej (advisor)
The diploma thesis deals with technology for the implementation and use of asphalt concrete for very thin layers (BBTM) with use of asphalt binder of high-polymer modification (HiMA). Further, there are described selected and performed functional tests. Thesis also contains design of a mixture for bituminous concrete type targeted for very thin layers with different types of binders. After a suitable design of the mixture, laboratory tests were carried out (stiffness modulus, resistance to permanent deformation, low temperature characteristics, water resistance and particle loss). The output of this work is a set of measured values and processed results with their interpretation.

Vliv aplikace plazmatem aktivované vody na půdní strukturu
Jedlička, Jan
Progress can not be stopped even in agriculture, new techniques and technologies are applied and also interconnected with new specializations. In addition, alternative sources for fertilizers and plant protection products are being researched. Recently, the possibility of using plasma-activated water (PAW) in crop production as a source of nitrogen, along with fungicidal and bactericidal effects have been pointed out. For the time being, however, there is no verified effect on soil properties. This work aimed to verify the effect of PAW application on the soil structure, or water resistance of soil aggregates. The values of two types of PAW (PAW-AC, PAW-DBD) were assessed against the control (distilled water). The container experiment was administered in the form of gradual watering of the soil in flower pots and gradual termination in 5 terms (1st term 525 ml, 2nd term 825 ml, 3rd term 1125 ml, 4th term 1425 ml, 5th term 1725 ml). Soil samples were taken from the flowerpots in 3 layers (Top, Center, Bottom) to verify the potential accumulation of fluid efficiency in some parts of the container. From the comparison of two variants of plasma-activated water (PAW-AC and PAW-DBD) with the control (distilled water), it can be seen that neither variant of PAW violates the stability of soil aggregates and therefore the soil structure. Based on the pilot experiment, it would be possible to state that the application of PAW does not worsen the condition of the soil structure and could become part of agricultural management without affecting this property. However, further experiments with other soil types are needed.
