The usage of asphalt and concrete recycled materials to roads
Svrčina, Vít ; Valentin, Jan (referee) ; Stehlík, Dušan (advisor)
Currently it is important to address the re-use of building materials from construction reconstructed or upgraded roads. Commonly used technologies cold and hot asphalt recycling are starting using to complement with technologies using cold asphalt mixtures with rejuvinators or softeners. This type of asphalt mixtures could be used in pavement constructions with lower traffic load. This thesis deals with the design and laboratory assessment of unbound and bound mixtures R-material and recycled concrete. This thesis is experimentally testing the possibility of using functional tests to optimize the design of asphalt mixture with 100% representation of R-material with a possible revival of asphalt emulsion with a rejuvenator.

Asphalt recycled material to cold asphalt mixtures
Kotas, Vojtěch ; Varaus, Michal (referee) ; Stehlík, Dušan (advisor)
The thesis is focused on the use of R-material into cold asphalt mixtures, which is modern method using recyclate into subgrade of roads. Concretely, it deals with basic properties of R-material, such as grain size and compaction. It practically verifies and compares properties of cold asphalt mixtures with cement, asphalt emulsion or with combination of this two binders. As reference testing method was chosen test of tensile splitting strength.

Cold Mix Asphalt
Kolesniková, Simona ; Valenta, Jakub (referee) ; Šperka, Pavel (advisor)
The diploma thesis deals with the issue of cold asphalt mixtures, which are commonly used for temporary repairs of potholes on roads, especially in winter months. The theoretical section describes some of the world´s researches on this topic. This section also includes manufacturers of cold asphalt mixtures in the Czech Republic and products available on the Czech market are presented. The practical part describes the properties of the materials used, the results of laboratory testing on test speciments made of cold asphalt mixtures and their comparison with the properties of asphalt concrete for wearing course. The effect of hot mix asphalt temperature during compaction on selected properties i salso analysed.
