Sustainable Asphalt Recyclate Base Course
Spies, Karel ; Tanečková, Pavlína
In the construction industry nowadays, it is the concepts such as sustainability, recycling, emission and energy reduction which are coming to the fore. This article follows the same path, looking at the design of new, recycled road subbase layers. These layers are almost 100% composed of recovered reclaimed asphalt, crushed to the appropriate fraction. This reclaimed asphalt is either mixed with a suitable binder, heated to a low temperature, or a combination of both effects occurs. The research described in this paper is partially related to the newly developed standard ČSN 73 6147 Cold recycling of pavement structural layers [1]. The aim of this research is to economically and environmentally reuse reclaimed asphalts of lower quality, specifically in the subbase layer of pavements. Otherwise, this precious material is mainly used for the backfilling of roadsides.

Cold recycling of flexible pavements
Řehulka, Martin ; Koudelka, Tomáš (referee) ; Varaus, Michal (advisor)
The bachelor´s thesis is focused on recycling of the flexible pavements in general, namely cold recycling. This modern technology was introduced in the Czech Republic after 1989. The first half of the thesis describes theoretically various types of recycling of flexible pavements, where the greatest attention is paid to this technology. The second part describes the section of the modernization D1 motorway where this cold recycling was applied. The technological process, including visual documentation and control tests, is documented.

Cold recycling
Šperka, Pavel ; Stehlík, Dušan (referee) ; Hýzl, Petr (advisor)
Bachelor’s thesis focuses on the processing of knowledge of flexible pavements cold recycling, especially on the technologies if full depth reclamation and partial cold recycling in-place and the benefits or reasons for the increased use in the Czech Republic. In the practical part of the thesis the current status of selected sections, which were made by practical cold in-place recycling technology, is evaluated. In the end of the work the success of this technology is evaluated.

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 asphalt mixtures with R-material
Ševc, Jan ; Mondschein,, Petr (referee) ; Stehlík, Dušan (advisor)
The thesis is focused on the use of R-material into cold asphalt mixtures. It deals with cold recycling and with input materials for this technology. It verifies properties of R-material and residues of bituminous binder. It also verifies properties of designed cold asphalt mixtures by the probative controls (indirect tensile strenght and water resistance). Furthermore is focused on the experimental measurement of selected mixtures to ensure more characteristics. The amount of homogenity of R-material, quantity and quality of residues bituminous binder is essential for positive results.
