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.
