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 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.

The usage of the quarried aggregates to base layers of pavements
Borkesz, Michael ; Mondschein,, Petr (referee) ; Stehlík, Dušan (advisor)
The work deals with the possibilities of using fine crushed and quarried aggregate to base layers of roads. The introduction of the theoretical part explains the origin of this type of aggregate. There are also described the tests, which were used to verify the attributes and features of these mixtures and their use in cemented base layers of roads. In a brief way, the work also deals with foreign research and the possibilities that arise from it. In the practical part is then described the process of mixture preparing and laboratory tests carried out on them, the production of test specimens, load tests of these specimens and interpretation of the results. The conclusion summarizes the findings. Here are also discussed ways to apply them in practice.
