Slurry surfacing
Koudelka, Tomáš ; Komínek, Zdeněk (referee) ; Hýzl, Petr (advisor)
This thesis is focused on microsurfacing technology. The theoretical part describes modern trends especially in the field of coloured surfaces and special system Flexiplast®. The practical part presents the results of conducted tests, particularly tests of breaking time, cohesion, determination of wearing and determination of friction after polishing. The key advantage is that it specifies which aggregates, which were taken from quarries through the Czech Republic, are convenient for this specialized technology. It was verified that RAP material suits use in microsurfacing. Furthermore, colour mixtures are viable for practical application which was confirmed by tests in the laboratory and trial lying as well. Special use of technology in the system Etanpalst and pictures which show field work are presented.

Microsurfacing
Koudelka, Tomáš ; Stehlík,, Dušan (referee) ; Hýzl, Petr (advisor)
This thesis is focused on slurry surfacing technology, particularly on microsurfacing. The theoretical part describes various issues of this technology: composition, manufacturing process, ecology, storage, making and design of the mixture. The practical part presents results of cohesion tests, wearing tests, consolidation and breaking time that has been performed on the mixture for microsurfacing. During the tests, the temperature of both bitumen emulsion and aggregate has been changed several times.

Slurry surfacing - composition and quality issue
Dostál, Filip ; Koudelka, Tomáš (referee) ; Hýzl, Petr (advisor)
This thesis is focused on slurry surfacing technology, particularly on microsurfacing. The theoretical part describes the differences between the slurry seal and microsurfacing. Ingredients for the production and laying. There are also described their advantages. The practical part presents proposal of mixture and demonstrate that the service of life of the emulsion mixture is closely related to the content of residual binder and composition of microsurface.

Microsurfacing using Reclaimed Asphal Pavement
Kolesniková, Simona ; Valenta, Jakub (referee) ; Šperka, Pavel (advisor)
The road network in the Czech Republic is almost 55,738 km long and its maintenance has been underfunded for a long time. It is therefore necessary to look for ways to extend the overall service life of roads. Microsurfacings belong to the emulsion slurry layers and are made up of a thin layer of a mixture of aggregate and modified asphalt emulsion. It is a pavement maintenance technology used to extend the service life of pavements by 5 to 9 years. As the supply of quality aggregate is gradually decreasing and the price of feedstock for microsurfacing is increasing, the possibility of incorporating R-material into this technology needs to be addressed. This thesis deals with the replacement of natural aggregates in microsurface R-material in the amount of 100 %. In the framework of the work, the formulation of the microsurface with R-material was optimized.
