The utilization of the asphalt and concrete recycled materials to roads
Žďára, Zbyněk ; Šperka, Pavel (referee) ; Stehlík, Dušan (advisor)
This diploma thesis is divided into two parts, theoretical and practical. The is a review om the topic of recycled asphalt pavement and recycled concrete and their possible use in road construction in the theoretical part. The individual chapters deal with describing these materials, their production, and their use in construction layers of pavements. In the next chapters the attention is also paid to their problematic features and foreign experience using these materials in pavements. In the practical part, laboratory samples of recycled asphalt pavement and recycled concrete and their mixtures with cement are tested. The main purpose is to verify the applications of these mixtures of recycled asphalt pavement and recycled concrete in the bonded base layers of the pavement. Another purpose is to compare how these mixtures individual properties with different proportions of both components and different amounts of cement will be different. In the end, the two mixtures with the best properties was selected and the modulus of elasticity was experimentally determined for the possibility of replacing the currently used base layers and the economic evaluation of this design was made.

Use of recycled building materials to urban pavement constructions
Průdková, Hana ; Hýzl, Petr (referee) ; Stehlík, Dušan (advisor)
This bachelor thesis describes the possibilities of construction and demolition waste management. It examines the issue of allocation and management of this waste and evaluates possibilities of their further use. It deals with production and use of recycled materials in construction of urban roads and economic advantage of recycled materials in comparison to natural aggregates. This work also discusses the issue of aerated concrete, as a modern building material, that will soon appear in construction and demolition waste to a greater extent. The practical part examines properties of mixed recyclates with a certain amount of brick and aerated concrete particles by testing the bulk density of grains and water absorption, freezing and thawing resistance and crushing resistance.

Waste building materials to base layers of the pavements
Žďára, Zbyněk ; Hýzl, Petr (referee) ; Stehlík, Dušan (advisor)
This bachelor thesis is divided into two parts, theoretical and practical. In the theoretical part, there is processed information about recycled construction waste and their possible use in road construction in the form of research. The individual chapters deal with the description of these materials, their production, their use in base layers of the pavement and attention is also paid to their problematic features and foreign experience. In the practical part, laboratory samples of recycled asphalt pavement and recycled aggregates were tested. The main purpose was to find out if it was possible to use a mixture of recycled asphalt pavement and recycled aggregates in the base layers of the pavement with a low traffic load. Another purpose was to compare the properties of mixtures with different content of both recycled materials and to see how the bearing capacity of these mixtures changes when an elevated temperature is applied to them.
