Abstract:

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.

Keywords:

Additives, mixing temperature, stiffness module, low-temperature characteristics, amide waxes, FTP paraffin, R-material, recycling, frost cracks.
