Evaluation of fatal traffic accidents
Nekulová, Pavla ; Dašková, Jaroslava (referee) ; Kudrna, Jan (advisor)
The aim of bachelor’s thesis is the evaluation of the influence of variable surface characteristics of roadways (skid resistance and longitudinal unevenness) on fatal traffic accidents in The South Moravian Region in 2011. This bachelor’s thesis contains characteristics of chosen high accident locations and measurement results of the longitudinal friction coefficient and longitudinal unevenness of road surface.

New trends in the field of stone mastic asphalts
Pfeiferová, Magdaléna ; Varaus, Michal (advisor)
The work consists of two parts. The first part is focused on the determination of an anti-skid properties of the test section on Vídenská street. The anti-skid properties will be measured using a pendulum tester and macrotexture will be set at the same time. Microtexture will be measured using a volumetric patch technique. In the second part we will try to gain an initial experience with design and testing of a low noise stone mastic asphalt. We will set basic characteristics and at the same time compare with a standard stone mastic asphalt. For the comparison two various bituminous binders are used. The water sensitivity, resistance against rutting and stiffness moduli are compared.

Open-graded asphalt concrete filled with a special cement grout
Hruška, Lukáš ; Mondschein,, Petr (referee) ; Hýzl, Petr (advisor)
Aim of this thesis is the usage of the open-graded asphalt concrete filled with a special cement grout in the road structures. Thesis defines the main concrete properties and explains related legislation and norms that apply. In addition, laboratory design of asfalt mixtures and a tree kind mortal filler and possibilities of mortal filler pigmentation are dealth with. Finally, thesis evaluates the results from various laboratory tests that were performed on the specimens made from final mixtures.

Skid resistance of pavements
Stránský, Jakub ; Stehlík, Dušan (referee) ; Hýzl, Petr (advisor)
Bachelor’s thesis main purpose is to process the knowledge about skid resistance, its mesurement, the equipment used and its failures and suitable repairs of solid and nonsolid roadways. The practical part evaluates skid resistance properities of selected highway sections with solid and nonsolid surface on the basis of measured values of PTV.

Analysis of selected properties of horizontal road marking
Šašinková, Daniela ; Jůza, Petr (referee) ; Tokař, Stanislav (advisor)
This diploma thesis deals with the analysis of selected properties of horizontal road marking (HRM). In terms of anti-skid properties measurements are made to determine the longitudinal friction coefficient, the coefficient of adhesion under different conditions and skid resistance of HRM. Measurements of anti-skid properties are supplemented by measurement of retroreflection of HRM. The theoretical part describes the current state of the issue, general characteristics of horizontal road marking and quantities measured in this thesis (friction and adhesion). The practical part consists of description of used measuring devices, custom solution and results analysis. The solution consists of the description of the measured samples, their preparation, subsequent measurement and a detailed description of the method of measured data evaluation. Data analysis is based on comparison of results obtained from individual sample groups and on comparison of measured values among themselves. The thesis is supplemented with photo documentation and video footage.

Study of the effect of concrete composition on the abrasion surfaces
Hoško, Marek ; Reiterman, Pavel (referee) ; Hela, Rudolf (advisor)
This work deals with summarizing knowledge on issues related to the loss of skid resistance properties of roads, which is caused by surface abrasion. Then indicates the relation between types of aggregates and paste volume to abrasion, impact compressive strength, aeration rate and different types of finishes. In the practical part were designed recipe CB II with different types of coarse aggregate. Samples were tested for abrasion method according to Böhm according to CSN 73 1324 Determination of abrasion of concrete.
