Low temperature behaviour of asphalt mixtures
Štěpanovský, Vlastimil ; Stehlík, Dušan (referee) ; Hýzl, Petr (advisor)
In this thesis it was paid attention to behaviour asphalt mixture of low temperature. The theoretical part deals with the technologies for reducing of mixing temperature and with their comparison. The thesis is notionally divided into two parts. The practical part is focused on the assessment of low temperature features by the test of asphalt mixture resistance against the formation of frost cracks according to ČSN EN 12697-46. Three mixtures were tested. The aim was to find if the low-temperature characteristics get worse compared to the commonly tested mixtures of the same gradation.

Reducing the operating temperature of the production and laying of asphalt mixtures
Komenda, Radek ; Valentin,, Jan (referee) ; Hýzl, Petr (advisor)
The subject of this thesis is the issue of reduction of the operating temperatures in the production and laying asphalt mixtures with a more specific focus on influencing the functional properties of these mixtures, especially low-temperature parameters. The thesis is notionally divided into two parts. The first part refers to the low-temperature asphalt mixtures and the second part pays the attention to asphalt mixtures with an added R-material. For production of asphalt mixtures in the first part of thesis were used five additives and for the second part were used a total of four different asphalt mixtures which differs in the participation of added R-material. Both parts are divided into a theoretical part, which discusses the existing experience, the use of these mixtures and the practical part, which analyses in detail the tested mixture ( the composition and preparation of tested specimens ) and deals with the result of laboratory test. In particular, it is a test of asphalt mixture resistance against the formation of frost cracks according to ČSN EN 12697-46 and by comparing the individual mixtures in comparison with the reference sample and among each other.
