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.

Recycled aggregates to asphalt mixtures of the flexible pavements
Kropáč, Pavel ; Zdřálek, Petr (referee) ; Stehlík, Dušan (advisor)
This thesis deals with the theoretical part of the creation, distribution and recycling of construction and demolition waste. Subsequently covers made from these recycled construction and demolition waste and its potential application in structural layers of the pavement. In the practical part of the thesis deals with monitoring the overall properties of nine asphalt mixtures with different proportion of recycled concrete aggregate and asphalt binder, which are designed and intended for bed asphalt pavement. The recycled concrete aggregate and asphalt are performed various laboratory tests, the results are subjected to a comparison with the relevant standards and TP 210. The conclusion is made price comparisons of asphalt mixtures.

Study the possibility of using recycled aggregate concrete for the manufacture of structural concrete
Skriňáková, Eva ; Stehlík, Dušan (referee) ; Hela, Rudolf (advisor)
This bachelor's thesis is aimed on the issues of using aggregate from recycled concrete rubble. The introduction describes the possibilities of concrete recycling and methods for fresh and hardened composite recycling. Next mentioned are physical and mechanical properties of recycled aggregate reused in concrete and comparison with natural aggregate concrete. Last part of theoretical section presents the opportunities of using recycled concrete to sub-base layers and concrete pavements. The practical section is focused on the application of recycled concrete aggregate to design concrete mixture of required strength class and verifying the possibility of usage in the exposure class XF3 and also design hydraulically bound course. The results of the practical section is to determine the suitability of recycled concrete usage for concept mentioned above.

Recycling of the construction waste
NOVÁČKOVÁ, Pavlína
The growth of waste is a phenomenon which is typical for the economically developed society and concurrently one of major problem with environmental protection. Therefore it is necessary legislatively regulate the increasing volume of waste, support waste recycling and support consequent use to keep the sustainable development. Construction and demolition waste presents a significant part of the total volume of waste. Recycling of construction and demolition waste has two basic advantages. On the one hand, it significantly reduces the capacity of waste repositories, and on the other hand recycled material is an important source of reusable materials.
