Usage of polymer modified bitumens and rejuvenators in asphalt mixtures
Maláník, Stanislav ; Hýzl, Petr (referee) ; Dašek, Ondřej (advisor)
Diploma thesis deals with the influence of various dosing of Reclaimed asphalt pavement (RAP) using modified bitumen on the properties of asphalt concrete (ACO 11+) of cemented by polymer modified bitumen, while a rejuvenating agents are added into asphalt mixtures. The theoretical part of the thesis summarizes the basic knowledge of pavement recycling, polymer modified bitumens and their reuse in asphalt mixtures. The practical part deals with laboratory tests of ACO 11+ mixtures with the RAP proportion of 0 % to 50 %. The asphalt mixtures compared are evaluated by means of the Thermal Stress Restrained Specimen Test (TSRST) and Stiffness test. The results obtained within the diploma thesis can approximate the issue of recycling of asphalt mixtures with polymer modified bitumens.

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.

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.

Advanced detection of rogue access point in wireless networks
Šebestová, Dominika ; Pospíšil, Jan (referee) ; Fujdiak, Radek (advisor)
The aim of the bachelor’s thesis is to get acquainted with the available implementation options of Rogue Access Point (RAP) and the detection methods used to detect such points from the side of the client or server, and from the principles of the studied methods implement a solution that is able to detect various types of the Evil Twin (ET). The thesis covers implementation of detection methods based on TCP connection properties and a method monitoring data frames, specifically their arrival time, specific length and source and destination MAC address. Connection of these methods creates an universal detection methods on the client’s side that is tested on the experimental network.

Circulation
Reisová, Kristína ; Sikora, Erik (referee) ; Smetana, Matěj (advisor)
Urethral falls, crying tears, breathing mist, river of blood, sweat underneath, sneezing mildew, tides of saliva, bladder bays, springs under the skin, weeing spring, renal lagoon, stalactites in the nose,... Running around the water cycle, no beginning and no end. My voice is in it. When it flows, the voice sings. When evaporates it becomes steam, it whispers and when the rain starts to fall the rap begins. The water cycle is dependent on the water cycle, natural condition, and the weather. So I’m addicted to the environment, and the mood and atmosphere is what it is, and what it will be.

Evaluation of properties of PMB containing binder from RAP
Měšťanová, Petra ; Hýzl, Petr (referee) ; Dašek, Ondřej (advisor)
Subject of this diploma thesis is to describe the effect of adding different amount of aged binder recovered from RAP on the change of properties of polymer modified bitumen. The RAP containing unmodified bitumen and the RAP where we can expect bitumen modification are used to recover binder. The binder obtained from RAP is dosed into the virgin binder in amount of 15 %, 30 % and 50 %. The methods of recycling of flexible pavements, extraction and regeneration of asphalt binders, rejuvenating of their properties and methods of empirical and functional laboratory tests are described in the theoretical part. The practical part deals with evaluating and comparison of the results mixed binders properties.

take a deep breath and let the tears shed water
Gajdošová, Kristýna ; Poliačková, Martina (referee) ; Sterec, Pavel (advisor)
The aim of this work should be an attempt to materialize my subjective reflection of the blending of two different scenes and subcultures. It should reflect my perception of these subcultures and their similarities and differences, as well as how they relate to each other or to society at all. More than research, I would like to focus on my personal inner testimony.

Recycling of asphalt mixtures with higher amount of RAP
Klimek, Matěj ; Koudelka, Tomáš (referee) ; Varaus, Michal (advisor)
The theoretical part of the diploma thesis recapitulates the existing literature in the field of recycling asphalt mixtures with a higher content of RAP (Reclaimed asphalt pavement). The practical part of the diploma thesis examines changes in the properties of asphalt mixtures with a higher content of RAP, due to changes in mixing time. Five mixtures have been proposed for this research. It is an asphalt mixture intended for the road abrasive layer (ACO 11+). Reference mixture "A" without RAP, with a standard mixing time of 25 seconds. Mixture "B" with 40% RAP, without rejuvenator, with an extended mixing time of 40 seconds. Mixture "C" with 40% RAP, with rejuvenator and standard mixing time. Mixture "D" with 40% RAP with rejuvenator and extended mixing time of 40 seconds. Mixture "E" with 40% RAP, with rejuvenator and extended mixing time of 55 seconds.
