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.

Cold asphalt mixtures with R-material
Ševc, Jan ; Mondschein,, Petr (referee) ; Stehlík, Dušan (advisor)
The thesis is focused on the use of R-material into cold asphalt mixtures. It deals with cold recycling and with input materials for this technology. It verifies properties of R-material and residues of bituminous binder. It also verifies properties of designed cold asphalt mixtures by the probative controls (indirect tensile strenght and water resistance). Furthermore is focused on the experimental measurement of selected mixtures to ensure more characteristics. The amount of homogenity of R-material, quantity and quality of residues bituminous binder is essential for positive results.
