Issue of asphalt mixtures with coarse-grained aggregates
Koblížek, Ondřej ; Hýzl, Petr (referee) ; Dašek, Ondřej (advisor)
The diploma thesis deals with the design of asphalt mixture of asphalt concrete type for base courses with maximum aggregate grain up to 32 mm and investigates the influence of the amount of asphalt binder on the properties of this mixture. The theoretical part describes the problem of aggregate shortage in the Czech Republic and the division of aggregates into various categories. In the next part, the laboratory used tests (needle penetration determination, softening point determination, compaction degree, determination of the stiffness modulus, low temperature properties and wheel tracking) are described in detail. The practical part describes the used materials, the results of the laboratory tests, their comparison and evaluation.

Coarse-grained asphalt mixtures
Brida, Peter ; Hýzl, Petr (referee) ; Dašek, Ondřej (advisor)
The diploma thesis is focused on the comparison of the influence coarse-grained aggragate on the properties af asphalt concrete. The theoretical part describes issue of production and usage of asphalt mixtures. The practical part evaluates multiple types of asphalt mixtures and describing their properties. Stiffness by a two-point bending test, a wheel tracking test and low-temperature cracking and properties by uniaxial tension test were used to evaluate the properties of the mixtures.

Use of RAP in coarse-grained asphalt mixtures
Teslík, Jozef ; Dašek, Ondřej (referee) ; Hýzl, Petr (advisor)
The diploma thesis examines the possibilities of using R-material in coarse-grained asphalt mixtures for ACP32 base layers. The theoretical part deals with the availability of aggregates in the Czech Republic and also solves the issue of producing asphalt mixtures with a higher content of R-material. The theoretical part also compares the use of R-materials in the Czech Republic with other countries. The practical part deals with the design, production and testing of selected mixtures. To determine the properties of the mixtures, the rolling wheel tests, TSRST and the determination of the modulus of elasticity were selected.

Coarse-grained asphalt mixtures
Rimel, Jindřich ; Dašek, Ondřej (referee) ; Hýzl, Petr (advisor)
The diploma thesis investigates the properties of coarse-grained asphalt mixtures ACP 32, which are compared with the properties of ACP 22 mixtures. The theoretical part deals with the composition of asphalt mixtures, their production, transport and laying. Experience with using coarse-grained mixtures around the world is also presented. The practical part deals with mixture design, production and testing to assess the properties of the mixtures. The tests selected for the comparison of the properties are wheel tracking, TSRST and stiffness by a two-point bending test.
