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.

The thesis deals with the experimental determination of the resilient modulus using cyclic triaxial test with the selected unbound mixtures of the base course of the pavement. The aim is to verify whether the proposed modulus-resilient in the regulation TP 170 based on the statisticaly verified data dating several decades ago is still valid in the present. Furthermore, the thesis deals with the dependence between the measured and the calculated values of the modulus resilient Mr from the cyclic triaxial test and the California Bearing Ratio tests. For the classification of the selected materials, further tests are used in the thesis, such as granularity and compaction tests.

The topic of the master’s thesis is reconstruction of the the road II/605 between municipality of Holoubkov and municipality of Rokycany (Borek) including local adjustments of the road in urban area of municipality of Svojkovice. The reasons for this reconstruction are insufficient parameters of current condition of the road. In Svojkovice are solved adjustments of crossroads, bus stops, parking bays, pavements and bicycle paths.

The subject of my diploma thesis is to design the intersection of roads I/44 and II/453 in urban area of Jeseník. Part of the proposal is to address traffic and pedestrian connection to the adjacent tertiary roads.

This master's thesis deals with the possibility of special asphalt-rubber mixture using - Stress Absorbing Layer (SAL). In the theoretical part the SAL and test methods are described. In the practical part, several different mixtures are designed and selected mixtures were tested. Low-temperature characteristics, permanent deformations, bending tensile relaxation, stiffness modulus and fatigue properties were determined. Based on the test results the mixtures were compared and their benefit is evaluated according to Performance Pavement Design Method, the pavement structure was evaluated by using of computer programme LayEps.

Master's thesis will deal with the second phase of shifting I/9 Dubice - Dolni Libchava passing west of the Ceska Lipa with an approximate length of 3 km stretch. Estimated start-up of this section is in 2014. This project should build on in the future by-pass Ceska Lipa and Novy Bor, which is currently without funds for implementation by 2025. Traffic load after completion of the by-pass should be approximately 16500 vehicles / 24 hours in 2030. The section is designed in the category S 9.5 with optional solving two major intersections. This thesis will focus on reducing the cost of construction of the section.

As part of my master's thesis I have conducted a visual inspection and record failures of bridge roadway at selected highway bridges, roads D47, D3 and D8 and photographic documentation, which is included in Annex. Also I have based on their speeches and documents the results of control tests determine their causes and to propose appropriate repair or maintenance.

The diploma thesis is focused on insufficient capacity problem of roundabout I/35, I/57 and II/150 in the Valašské Meziříčí town. It is based on engineering survey according to which three possible models are designed. Capacity assesment is made on each of these models. Throug the evaluation is selected the most suitable design of turbo roundabout type "knee", which is technically processed and substantiated by text and drawing documentation.

The subject of my thesis is the project-level documentation for the building location on the roundabout on Vojackovo namesti in Prostejov. Current condition create light controlled crosroad of roads II/150 and III/44934. In this thesis was examinated several options and for selected option was elaborated capacity assessment. For the final shape of new designed crossroad, wich is technically elaborated Attached are the text and drawing documentation in accordance with all legal and technical standards.

Currently it is important to address the re-use of building materials from construction reconstructed or upgraded roads. Commonly used technologies cold and hot asphalt recycling are starting using to complement with technologies using cold asphalt mixtures with rejuvinators or softeners. This type of asphalt mixtures could be used in pavement constructions with lower traffic load. This thesis deals with the design and laboratory assessment of unbound and bound mixtures R-material and recycled concrete. This thesis is experimentally testing the possibility of using functional tests to optimize the design of asphalt mixture with 100% representation of R-material with a possible revival of asphalt emulsion with a rejuvenator.
