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.

The use of glassgrids in asphalt pavement structure
Sadil, Dominik ; Šperka, Pavel (referee) ; Kudrna, Jan (advisor)
The bachelor thesis deals with the use of fiberglass grids in asphalt layers. These materials are used as reinforcement materials in road construction primarily to partially elimination or delay the formation of cracks in the roadway and to transfer the tensile loads that are distributed to the sub-layers. The bachelor thesis tests the properties asphalt layers reinforced by geogrids by using selected functional tests and also was monitored their behavior between asphalt layers. At the same time, the thesis determines whether these functional tests are practically applicable for asphalt layers with fiberglass grids.

Innovative Asphalt Mixtures for Wearing Course with a Higher Content of Reclaimed Asphalt Pavement
Spies, Karel ; Hegr, Zdeněk (referee) ; Šperka, Pavel (advisor)
This master's thesis deals with the design of two asphalt mixtures for a wearing course containing 35 % R-material. The asphalt mixtures use a soft bitumen modified with crumb rubber (CRMB) or the unmodified soft binder itself with a penetration grade of 70/100. The work verifies the effect of crumb rubber as a bitumen modifier on the properties of the asphalt mixture with reclaimed asphalt pavement (RAP). At the same time, the work deals with the possibility of using higher amounts of reclaimed asphalt pavement only in combination with a softer binder without the use of rejuvenating additives. The properties of asphalt binders and mixtures are verified using suitable functional tests. Furthermore, the proposed mixtures and their results are compared from various perspectives. At the same time, the thesis in the theoretical part deals with the dosing of a reclaimed asphalt pavement into the asphalt mixture and describes the handling and use of reclaimed asphalt pavement in the Czech Republic and abroad

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.
