Research in the field of construction elements and design of concrete pavements
Grošek, Jiří ; Birnbaumová, Marie (referee) ; Vébr,, Ludvík (referee) ; Varaus, Michal (advisor)
The presented dissertation is focused on research in the field of dowels and design of concrete pavements using the finite element method. The theory part describes the history and the currently used techniques in the world and in the Czech Republic. The practice part of the dissertation contains a description of design methods, diagnostics of concrete pavements by using FWD and a description of laboratory tests on beams with inserted dowels. The results of measurements and modelling are verified on real operating conditions on testing fields. Based on the dissertation results, the amendment of the Czech standard ČSN 73 6123-1 regarding the position of dowels were proposed and approved. In addition, methodological guidelines of the Ministry of Transport regarding the measurements of the dowels and tie bars position and diagnostic by FWD was approved. The conclusion of the work summarizes and emphasizes the results of the dissertation.

Analysis of time of construction
Šmol, Tomáš ; Bařica, Zdeněk (referee) ; Aigel, Petr (advisor)
This bachelor thesis focuses on assessment of time requirement of building labour during reconstruction of certain part of highway D1 and D2 and it also compares particular sections with regard on submitted work schedule, established range of work, different surface of roadway casing and various (unspecified) builders. The goal is to compare speed of implementation of realization in locations of concrete and asphalt casings, dependence on state of subsoil, existence of crossings of middle separating strips and length of certain parts of highway.

Relationship between macro- and microscopic sings of alkali-silica reactivity in concrete
Burdová, Anna ; Přikryl, Richard (advisor) ; Martinec, Petr (referee)
This thesis deals with deterioration observed in cement-concrete cover (CBK) for three selected road sections of highways in the Czech Republic. The main objective was to determine whether concrete failure arose due to alkali-silica reaction, or other mechanism. The deterioration of concrete failure was observed in the macroscopic and microscopic scale. The mostly macroscopically observed deterioration of the concrete were cracks breaking the surface and inner parts of concrete. In micro- scale the microcracks and alcali-silica gels were observed. The CBK deterioration was quantitatively determined by three main parameters: specific length of microcracks on the CBK surface, specific length of microcracks in the drill cores and volume of alcali-silica gels and microcracks in thin sections. According to these indicators it was possible to distinguish two different types of CBK deteriorations. (1) Degradation mainly associated by alkali-silica reaction (observed on highways D11 - Vrbová Lhota and D1) and (2) degradation connected with another mechanism (cycles of freezing and thawing, mechanical degradation) was observed on the highway D5.
