Milling of asphalt layers of pavements
Brida, Peter ; Hýzl, Petr (referee) ; Dašek, Ondřej (advisor)
The bachelor thesis is focused on the comparison of the influence of the milling machine movement speed on the properties of RAP (reclaimed asphalt pavement). The theoretical part describes issue of production and usage of RAP. The practical part evaluates the sieve size distributions of these materials and needle penetration and softening point of bitumen recovered from RAP samples.

Properties of asphalt mixtures with RAP
Trnka, Lukáš ; Coufalíková, Iva (referee) ; Dašek, Ondřej (advisor)
The bachelor thesis deals with the properties of asphalt mixtures with reclaimed asphalt. Possibilities of rejuvenate of binder contained in reclaimed asphalt are mentioned in the theoretical part. There is explained the principle of rejuvenators function, types of rejuvenators and ways of rejuvenators dosing into the asphalt mixture. The procedures for performing the stiffness modulus test (2PB-TR) and the low temperature (TSRST) test are described in the following part. Individual tests are evaluated and asphalt mixtures are compared in the practical part of bachelor thesis.

Properties of asphalt mixtures of SMA-type with RAP
Acuna Subia, Luis Carlos ; Hrbek, Kamil (referee) ; Varaus, Michal (advisor)
The aim of the diploma thesis is to verify and compare the properties of bituminous stone mastic asphalt, namely SMA 11S with modified PMB 45 / 80-55 asphalt binder or 50/70 road bitumen binder with rubber granulate. Comparison of properties is performed using functional tests. The thesis is divided into the theoretical and practical part. The theoretical part deals with the familiarization with the use of the SMA mixture, the selected concepts concerning recycling of non-leveled roads are described and described. Attention is paid especially to the recycling of roads in the Czech Republic with an emphasis on hot recycling on the incinerator, which allows increased dosing of Reclaimed Asphalt into asphalt mixtures. In the practical part, the results of the functional tests of the SMA 11S mixture, which have been taken from the test section, are processed and evaluated.

Design of asphalt mixtures with the use of higher amount of RAP
Pavličík, Petr ; Matoušek, David (referee) ; Varaus, Michal (advisor)
In the introduction of the Master’s thesis describes for obtaining and processing of reclaimed asphlalt. Major point of the thesis is design of asphalt mixtures with use of higher amount of RAP for asphalt binder course. Asphalt mixtures were designed with contents of 0%, 30%, 50% and 70% of RAP. On each asphalt mixtures were compared parameters set out by functional tests – resistence to permanent deformation and resistence to water.
