The utilization of the pavement waste materials to roads
Furdaničová, Alice ; Šperka, Pavel (referee) ; Stehlík, Dušan (advisor)
The diploma thesis deals with the use of recycled asphalt with aggregate in a hydraulically bound mixtures. The mixture is determined in the base or sub-base course of the pavement. The theoretical part of the diploma thesis describes the base course of the pavement, the production of recyclates from construction demolition waste, the acquisition and processing of recycled asphalt, the road reuse and recycling. The thesis is enriched by a contribution from the implementation of recycled asphalt laying into the base course of the communication company SKANSKA a.s. and ČNES a.s. The next chapter describes detailed experiences with recycling abroad. The thesis also contains a description of laboratory tests, which are important for evaluating the properties of mixtures with recycled asphalt. The practical part verifies the suitability of the mixture of recycled asphalt and aggregate for the road surface by testing the transverse tensile strength, compressive strength and frost and water resistance. The mixtures used are found to be suitable for pavement base course.

The building waste for bound mixtures of the pavements
Pokluda, Radim ; Valentin,, Jan (referee) ; Stehlík, Dušan (advisor)
In the theoretical part of the thesis are generally characterized hydraulically bound mixtures, their types, classification systems, manufacturing technology and the laying. There are also described experiences from abroad with the use secondary and recycled materials in hydraulically bound mixtures. The practical part deals with the experimental verification of the possibility of the use of secondary materials in hydraulically bound mixtures in construction of road infrastructure. In road laboratory Institute of road structures Brno university of technology was the five proposed mixtures, an assessment of their parameters with regard to the possibility of using these mixtures in the road sub-base layers. The work is also aimed at comparison of results elasticity modules reached laboratory testing and experimental measurements on road polygon.

The usage of the fine aggregates to cement bound mixtures
Švarcová, Monika ; Hýzl, Petr (referee) ; Stehlík, Dušan (advisor)
This bachelor thesis occupies with use of fine aggregates in hydraulically bound mixtures for road pavement bases and sub-bases. The theoretical part describes properties of bound mixtures, aggregates and bound materials. This part also deals with laboratory methods used for bound mixtures and foreign research. In the practical part sand and gravel, crushed stone and recycled fine aggregates are used in bound mixtures with cement or cement and fluidized bed combustion ash. The unconfined compressive strength and frost and water resistance of bound mixtures are tested. The results of laboratory tests are evaluated and compared. The used mixtures are mostly found as suitable for pavement sub-bases.

Design of the bound mixtures to pavements
Hepner, Urban ; Pácha, Petr (referee) ; Stehlík, Dušan (advisor)
The bachelor thesis focuses on the monitoring of the impact of the shape on the tested bound mixture solid during the strength tests in an uniaxial stress. The theoretical part is devoted to the hydraulic binders bound mixtures, strength test in the uniaxial stress and furthemore discusses the foreign research concerning the topic of the strength ratio between a cylinder solid and a cubical solid. Practical part of the thesis describes the act of preparation of a mixture for the production of the test solids, laboratory tests provided on the prepared mixture, the production of the test solids and finally the following tests of the prepared solids strength in the uniaxial stress. All the results from the tests of the strenght in the uniaxial stress are in the end evaluated and compared to the foreign research.
