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.

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.

Use of waste building materials to roads
Průdková, Hana ; Hýzl, Petr (referee) ; Stehlík, Dušan (advisor)
This thesis consists of a theoretical and a practical part. The theoretical part collects available information on the current state of construction and demolition waste management. This section discusses demolition work, provides basic information on construction and demolition waste, and describes the recycling process. It also includes the most used types of recycled materials and their use in the roads. The thesis also explains the importance of the circular economy and compares prices of recycled and natural aggregates. The conclusion of the theoretical part is supplemented by foreign experiences. The practical part of this thesis focuses on the possibility of using concrete, asphalt and brick recycled and their mixtures cemented with hydraulic binders. The main goal was to verify the possibilities of using these recycled materials in the cemented base layers of roads. These options were verified and subsequently compared using laboratory tests. In the conclusion, there is an economic comparison of the use of recycled materials.
