The segragation of mixtures to pavement
Trávníček, Dušan ; Hýzl, Petr (referee) ; Stehlík, Dušan (advisor)
The work deals with the examination of repression and segregation in asphalt mixtures. The theoretical part is monitoring the current situation about the problem of segregation, which mainly refers to the practical adjustments during laying „risking“ asphalt mixtures on the formation of segregated places in the shelter layers of roads. The practical parts of the thesis are summarised measurements on six samples of the most commonly used asphalt mixtures to determine the segregation depending on the selected parameters. The work is describing and valorising a test for determining segregation according to ČSN EN 12697-15.

Characteristics of Municipal Solid Waste
Dvořáková, Markéta ; Benešová, Libuše (advisor) ; Zimová, Magdalena (referee) ; Innemanová, Petra (referee)
Objective knowledge about quantity, composition and physicochemical characteristics of municipal solid waste (MSW) in the Czech Republic will form the basis for decision- making when considering processing facilities or regional waste management systems. As the country continues to streamline its legislation to the European Union's solid waste mandates, the results of these studies were employed by the Czech Ministry of Environment to optimise the national waste management strategy. This doctoral thesis focuses on the composition of MSW, primarily the mixed MSW from three types of households in the Czech Republic (urban, mixed and rural) differentiated by their heating methods and possibility of waste disposal. The respective experimental work and data-collection took place in years 2008 and 2009. Methodology used in the analyses is based on the sieve analysis of mixed MSW within predetermined grain size fraction and on the final manual sorting of the waste by material categories. The physicochemical characteristics were measured according to the standard analysis methods. The composition of mixed MSW in urban and mixed households are similar. Some of the biggest differences were found in the quantities of certain subsample categories, especially fine fraction (matter smaller than 8 mm), between...

Recycled aggregate to pavement constructions of roads
Antošová, Klára ; Mondschein,, Petr (referee) ; Stehlík, Dušan (advisor)
The diploma thesis deals with using of recycled aggregate of concrete for base layers of pavement. The work is divided into practical and theoretical part. The theoretical part deals with basic concepts of construction and demolition waste, production, development and management of this waste in the Czech Republic. It also focuses on the principle of recycling and the use of recycled concrete in the Czech Republic and abroad. The practical part of the thesis deals with laboratory testing and assessment of recycled aggregates in bound, unbound and grouted courses layers of the base layers of roads.
