Characteristics of mixed building recyclates for subgrade og roads
Junek, Lumír ; Dašek, Ondřej (referee) ; Stehlík, Dušan (advisor)
The work deals with the use of mixed construction recycled material for earth bodies of roads. The theoretical part describes the production, usability and economic evaluation of recycled building materials against common natural materials. It then describes the necessary laboratory tests that examine its properties for the use of these materials in roads. In the last chapter, the work deals with foreign experience with the use of mixed construction recyclates for transport construction. The practical part examines the properties of the given recyclates for their use in the core using tests of soil freezing rate, California bearing ratio and immediate bearing index.

Waste building material to subgrade pavement
Masař, Daniel ; Hýzl, Petr (referee) ; Stehlík, Dušan (advisor)
The theoretical part of the diploma thesis searches the production of Construction and demolition waste and their subsequent transformation into the final recyclate and its possible use in roads. Attention is focused on the use of mixed recycled material into subgrade of the pavement and the characteristics of tests that must be performed before its used to the road. The next chapters pai attention to the problematic properties of recyclates, foreign experience with the use of mixed recyclate in Construction and the possibilities of its development. The practical part verifies the suitability of mixed recycled material into subgrade of the pavement using laboratory tests. The tests are performer on individual mixtures of mixed recycled material with cement, blast furnace slag or cement dust in various percentages. The results are then compared and it is evaluated which mixtures show the best properties. Part of the practical part is also the economic evaluation of these mixtures against commonly used materials.

The waste buildings material to subgrade of the pavement
Ševc, Jan ; Pecha, Karel (referee) ; Stehlík, Dušan (advisor)
The thesis is focused on the use of waste buildings materials to subgrade of the pavement. In detail it deals with monitoring the carrying capacity of the material used to replace unsuitable subgrade mainly of the urban road communications. It practically verifies California bearing ratio and resistance to frost and water of the waste buildings materials firmed by cement for possible use in subbase layers. The amount of residues in recycled bricks is essential for positive results in terms of the properties of materials in subgrade of the pavement.

Mixed builging recycled material for pavement subgrades
Masař, Daniel ; Hýzl, Petr (referee) ; Stehlík, Dušan (advisor)
The Bachelor thesis is focused on the use of mixed building recycled material for pavement subgrades. The theoretical part describes the production and usability of recycled building materials and also the economic evaluation against commonly used natural materials. The main point of the theoretical part is the use of mixed recycled material in the subsoil of roads with increased attention to the use in the active zone of road. It also describes laboratory tests that are important for evaluating the qualities of recycled materials and problematic qualities that can affect the life of a construction work. In a separate chapter, it presents foreign experience with the use of recycled building materials for building transport structures. The practical part verifies the suitability of mixed building recycled material to the active zone of road by tests of the California bearing ratio, soil freezing rate and crushing resistance by Los Angeles.

The frost susceptibility of the recycled materials to subgrade of the pavement
Nehybová, Eva ; Mondschein,, Petr (referee) ; Stehlík, Dušan (advisor)
In the theoretical part of the thesis, different methods of testing frost susceptibility in the Czech Republic and other countries of the European Union are compared. The practical part of the thesis deals with laboratory testing of frost susceptibility of concrete and mixed recycled materials using the direct method of frost heave tests as well as determining the California Bearing Ratio (CBR) and design module of elasticity using the cyclic triaxial test. Suitability of materials for construction of road infrastructure is then assessed on the basis of the results of these tests.
