New trends in the construction of flexible pavements
Palátová, Marcela ; Špaček, Petr (referee) ; Hýzl, Petr (advisor)
The aim of this thesis is to introduce innovations and trends in the construction of flexible pavement layers, which are used abroad. The paper is focused on some surfaces, which help to reduce noise pollution from traffic, and binders, which are based on natural ingredients called bioasphalt. It provides an information summary of increasing share of reclaimed asphalt in bituminous mixtures and introduces possible procedures that could lead to an increase in pavement life.

Frost susceptibility of improved soils to pavement subgrade
Lorenc, Daniel ; Špaček, Petr (referee) ; Stehlík, Dušan (advisor)
This diploma thesis deals with the issue of the effect of freezing on soils in subgrades of road structures. The theoretical part compares methods of determining the frost susceptibility of soils used in selected countries of the European Union and the Czech Republic. It also explains the principle of frost heave in subgrade layers. The aim of the practical part is to compare the direct and indirect method of determining frost susceptibility in the Czech Republic and the California bearing ration CBR or the immediate bearing ratio IBI.

SEO Analysis Tool
Špaček, Petr ; Očenášek, Pavel (referee) ; Ruttkay, Ladislav (advisor)
The thesis deals with SEO problems (Search Engine Optimization). The part of the thesis is creation of tool which analyzes web pages in multilanguage versions and results provides with appropriate educational effect for user. According the analyzing that can be also used in the regular interval it's possible to show optimization history. The tool uses Microsoft technologies, especially ASP.NET, SQL Server 2008 or Microsoft Server 2008 and is developed by Visual Studio 2010.

Profiling of Non-Core Part of Security System
Špaček, Petr ; Michal, Bohumil (referee) ; Kašpárek, Tomáš (advisor)
The thesis is focused on identifying and eliminating performance problems in the security system "AVG Server Edition 8.5 for Linux/FreeBSD", which is used for filtering SMTP traffic. It includes explanation of the principle of SMTP proxy filter and of the interconnection between AVG and the Postfix mail system. It describes methodology of testing, sample designing, measurement and data evaluation. Several performance problems were found and steps to eliminate them were carried out. Suggested optimization was tested and found effective.

Use of special binders for recycling of asphalt mixtures at mixing plants
Pěch, Pavel ; Špaček, Petr (referee) ; Varaus, Michal (advisor)
The thesis deals with the matter of usage of special asphalt binders for production of asphalt mixtures containing recycled materials in asphalt plant. For comparison analysis of characteristics of special binder used in roads is necessary to compose different mixtures of asphalt – one with binder containing R-materials, and another benchmark mixture with binder used in common mixtures without recycled materials. Investigation of features of mixtures with different binders is carried out by selected performance tests of asphalt mixtures. Evaluation and comparison of the results is described in the final section of the thesis.

The amount of damage determination in cases of defects and failures of flexible pavements road structures
Špaček, Petr ; Jůza, Petr (referee) ; Kledus, Robert (referee) ; Stehlík, Dušan (advisor)
This thesis is focused on possibilities of financial valuation of flexible pavements surface layers conditions, in connection with whole life cycle of the pavement and certain possibilities of their maintenance and repairs, in cases of defects and failures from forensic engineering point of view. There were carried out analysis of the topics connected with judging of flexible pavements surface layers defects and failures related to forensic investigation in the Czech Republic, as well as abroad. In this thesis there were created pricing models of the certain construction works which are related to repairs and maintenance of flexible pavements. Within the possibilities of the author, there were compared market prices of the particular construction works in selected regions with the prices according to generally used pricing systems in the Czech Republic. The goal of this thesis is to create unified methodology for amount of damage financial valuation in cases of defects and failures of flexible road pavements surface layers for forensic engineering practice in the Czech Republic.
