Network Game: Destroy the Submarine
Kudrna, Jiří ; Řezníček, Ivo (referee) ; Szőke, Igor (advisor)
The bachelor´s thesis describes the design and the implementation of the 2D network game "Destroy the submarine". In this game each player controls his submarine and tries to destroy the submarines of his opponents. The game can be played by more players via the computer network or on one PC. The application is developed in the C++ programming language with the help of the Qt framework. It is a multi-platform application.

Bituminous mixture for wearing course with increased content of reclaimed asphalt
Spies, Karel ; Šperka, Pavel (referee) ; Kudrna, Jan (advisor)
The bachelor thesis deals with design of asphalt mixture for wearing course, by performing functional tests according to ČSN EN 12697 (736160) Bituminous mixtures - Test methods for hot asphalt mixtures and comparison of its properties with asphalt concrete for wearing course (ACO 11 +) according to ČSN EN 13108-1 ed. 2 (736140) Bituminous mixtures - Specification for materials - Part 1: Bituminous concrete. The proposed layer is characterized by a high (50%) reclaimed asphalt pavement content (RAP) and the use of a crumb rubber modified bitumen (CRMB) without the use of rejuvenators or other softening additives. The aim of the work is to verify the expected properties of the asphalt mixture and point out the possibility of using larger amounts of reclaimed asphalt pavement in asphalt mixtures.

Double Layer Porous Asphalt with Aspahlt-rubber Binder
Klimeš, Petr ; Hegr, Zdeněk (referee) ; Kudrna, Jan (advisor)
The possibilities of double layer porous asphalt usage and rules for design of porous asphalt mixtures are introduced in this work. The porous asphalt mixtures PA 8, PA 11 and PA 16 are designed with different content of asphalt-rubber according to Marshall Test method. The water sensitivity, drainability, particle loss of these PA are determined. The permanent deformation and drainability of double layer PA 8 and PA 11 were also determined. The possibility of usage of this double layer porous asphalt with expected decreasing of traffic noise was proved.

Bituminous mixtures with a higher lifetime using recycled asphalt
Stromecký, Roman ; Musil, Vladimír (referee) ; Kudrna, Jan (advisor)
This diploma thesis deals with a project of asphalt mixtures with high stiffness modulus using R-material. The theoretical part describes the characteristics of these mixtures in the Czech Republic and in Switzerland. Further this part deals with the use of R-material in the Czech Republic and chosen other countries of the world, it also deals with the ways of recycling roads. The theoretical part also deals with the testing methods used. In the practical part two new asphalt mixtures of the high stiffness modulus type with the addition of 25 % R-material are suggested. As a base for these two mixtures a mixture of the high stiffness modulus type, which was taken from an asphalt mixing plant, was used. Tests were run on the binders and several functional tests (stiffness modulus, fatigue resistance, low temperature qualities) wer done on the suggested asphalt mixtures and also the mixture taken from the mixing plant. Consequently, the results were compared. The conclusion of the thesis is devoted to modelling a construction of a road using the program LayEps, which verified if the suggested mixtures could reduce the thickness of roads.

Evaluation and modelling of Traffic Noise
Černoch, Adam ; Spies, Karel (referee) ; Kudrna, Jan (advisor)
The task of the master's thesis is introduction with the problems of traffic noise, focusing on noise from road traffic. There is a description what is the noise, how it is formed, its resources and what are the methods of measuring. The following are the various noise reduction measures such as noise barriers and low noise pavements. The main attention is devoted to the noise generated at the tire / road that is reduced by these pavements. The practical part describes the implemented measurements on individual sections at various locations in our country. The measurement was carried by slightly modified method CPX with reference tire directly at the vehicle. The main aim was to evaluate the measurement data, make comparison of different low-noise surfaces with each other and with the commonly used surfaces. Then quantification of the rate reduction of the noise emission for a given section and verification of input data for noise modeling. In conclusion, the obtained results are summarized and based on them were confirmed very good acoustic properties with the recommendation to continue with measurements in the future.

Design and evaluation of asphalt rubber mixture
Hotař, Petr ; Dašek, Ondřej (referee) ; Kudrna, Jan (advisor)
The aim of bachelor thesis is to design the asphalt concrete for very thin layers using asphalt rubber and to perform laboratory tests according to ČSN EN 13108-2 and TP 148. The work is based on the literature review and respects properties of asphalt rubber. The expected properties of asphalt concretes for very thin layers are summarized and evaluated.
