Cold recycling of flexible pavements
Řehulka, Martin ; Koudelka, Tomáš (referee) ; Varaus, Michal (advisor)
The bachelor´s thesis is focused on recycling of the flexible pavements in general, namely cold recycling. This modern technology was introduced in the Czech Republic after 1989. The first half of the thesis describes theoretically various types of recycling of flexible pavements, where the greatest attention is paid to this technology. The second part describes the section of the modernization D1 motorway where this cold recycling was applied. The technological process, including visual documentation and control tests, is documented.

Analaysis of the Number of Vehicle Extrications at the -0.4 - 60.5 Section of the D2 Motorway Depending on the Traffic Rate
Hrdličková, Petra ; Bilík, Martin (referee) ; Libertín, Josef (advisor)
This diploma thesis deals with the processing of basic technical data for a designated motorway section in order to develop a technology for removing obstacles on the motorway. Depending on the predicted traffic intensity, they can predict the recovery and recovery services in the sections. The thesis deals with technological process work. Because poor recovery technology and ignorance of the vehicle construction result in consequential damage after an accident. The professional approach of the company leads to the minimization of these damages. Recovery and removal companies must have properly trained personnel and well-chosen rescue technology. This leads to a shortening of the time limit of the operation and thus also to the shortening of the columns. Another topic addressed will be the traffic intensity, which is important in the evaluation depending on the number of accidents and the number of interventions, in the places with the highest traffic intensity.

D1 Reconstruction of Bridge on Motorway D1-212 in Ostrovačice, Preparation and Realization of Structure
Kratochvíl, Tomáš ; Kratochvílová, Erika (referee) ; Šlanhof, Jiří (advisor)
The diploma thesis deals with preparation and realization of D1 reconstruction of D1-212 bridge in Ostrovačice. It is a motorway bridge that transfers traffic over road II / 386. The reconstruction will demolish the superstructure of bridge with bridge equipment and parts of the abutments and their new construction. The preparation of the project solves the engineering report, the block plan drawing, the financial and time schedule - by objects, the budget SO 201, the study of the implementation of the main construction technologys, the project of the site equipment, the design of the main building machines, the SO 201 time schedule, a desigh of the bill of quantities for structure, technical note for superstructure of a bridge and control and test plans. Part of the preparation of the building is the processing of the emergency plan.

Analaysis of the Number of Vehicle Extrications at the -0.4 - 60.5 Section of the D2 Motorway Depending on the Traffic Rate
Hrdličková, Petra ; Bilík, Martin (referee) ; Libertín, Josef (advisor)
Diplomová práce se zabývá zpracováním základních technických dat pro určený úsek dálnice za účelem zpracování technologie odstraňování překážek na dálnici. A to v závislosti na předpokládané intenzitě dopravy predikovat na daných úsecích výkony pro vyprošťovací a odtahové služby. Práce se zabývá technologickým postupem prací. Jelikož špatná technologie vyproštění a neznalost konstrukce vozidel má za následek následné škody po nehodě. Profesionální přístup firmy vede k minimalizaci těchto škod. Vyprošťovací a odtahová firma musí mít náležitě vyškolené pracovníky a správně zvolenou technologii vyprošťování. To vede ke zkrácení doby omezení provozu a tím lze řešit i dobu pro zkrácení kolon. Dalším řešeným tématem bude intenzita provozu, která je důležitá při hodnocení v závislosti na počtu nehod i počtu zásahů a to v místech s nejvyšší intenzitou dopravy.

Evaluating the Need for Truck Centres on the D1 Motorway between Prague and Brno
Spáčil, Tomáš ; Kudláček, Jaroslav (referee) ; Libertín, Josef (advisor)
This diploma thesis deals with a design of truck-centres count and location near the motorway D1. This design is a result of aspects which can influent truck-centres‘ count, size and location. There are derived the aspects on the basis of calculation of freight transport intensity till the year 2030 and its concurrence to accident frequency, traffic flow regulation, and also its concurrence to management of personnel labour (AETR), means of eventual maintenance need and means of vehicles’ reparation, services for motorway attendants and finally its concurrence to possibilities of controls by public authorities and police. In order to regulate freight transport traffic flows is calculated size of parking spaces and suggested their appropriate locations.

Bridge over a local road and a brook
Tichavská, Andrea ; Čihák, Petr (referee) ; Nečas, Radim (advisor)
The purpose of the master thesis is the design of the concrete highway bridge by European standards. The highway is situated on two independent prestressed load-bearing structures with cross-section area of constant dimensions over its length. The bridge deck is built on a falsework considering its proportions and obstacles under the bridge. The thesis contains the design and the assessment of the load-bearing structure in longitudinal and transverse direction including the calculation of cross beams and an anchorage zone.

Line constructions in selected EU countries: Study 5.300
Pulda, Jan ; Syllová, Jindřiška
Práce se zabývá procesem přípravy a povolování významných liniových staveb. Autoři dochází k závěru, že všechny uvedené státy upravují, ve srovnání s běžným stavebním řízením, zvláštním způsobem přípravu a povolování velkých liniových staveb. V žádném z analyzovaných států však neexistuje komplexní úprava určená společně pro všechny druhy liniových staveb.

Economic efficiency analysis of traffic buildings in Čzech republic
Němeček, Petr ; Mervart, Michal (advisor) ; Vrabec, Michal (referee)
In my work, I would like to focus on the way of evaluating economic efficiency of traffic buildings in Czech republic. This evaluation is in responsibility of Czech Directorate of Motorways and Highways DG. Evaluation is made by HDM-4 (Highway Development and Management version 1.30)aplication. Its funkcionality is provided by employees of Directorate but Reports of economic efficiency are made by private companies.Making projects in this software is quite difficult task, because of big amount of information which are required. Main aim of this work is to find out if this kind of analysis is appropriate for Czech road network or if there are some problems or difficulties in using HDM-4.
