Recycled material in Stone mastic asphalts
Motl, Vojtěch ; Coufalíková, Iva (referee) ; Hýzl, Petr (advisor)
The Bachelor’s thesis deals with an issue of adding a Reclaimed asphalt pavement (RAP) into surface courses, especially SMA 11S. The thesis is divided into two parts – theoretical and practical. The theoretical part defines the term RAP and explains how to gain RAP and how to use it for a hot recycling at asphalt plants. The practical part deals with the design of asphalt mixture containing 30 % of RAP, the preparation of test specimens, the description of executed tests and the results of those tests. The results are compared with SMA 11S without RAP.
Low volume roads
Kučera, Vlastimil ; Stehlík, Dušan (referee) ; Hýzl, Petr (advisor)
Thesis deals with an issue of low-volume roads and brings basic informations about their design. The most of the low-volume roads in the world are unpaved roads, while in the Czech republic there are not enought of experience with their construction, therefore a foreign literature was used as an almost exclusive source. The advantages of the roads with unpaved materials are, they are environment-friendly and money saving, therefore when correct procedure is used, good quality material is chosen and proper maintenance is used, they are advisable alternative to normally used asphalt surfaces. With increasing volume of vehicles their advantages decreases. They are suitable for a road surfaces in protected landscape areas, because they represents minor impact on the landscape.
PmB - Polymer modified bitumens
Venclíková, Michaela ; Dašek, Ondřej (referee) ; Hýzl, Petr (advisor)
In this bachelor thesis, there are described modified bitumens. The issue of modified bitumens will be explained in the theoretical part. In the practical part, it will be prepared set of modified bituminous binders with different degree of modification. Basic empirical testing and functional testing will be determined. The aim of thesis is to find the optimal source of unmodified bitumen for modification.
Permanent deformation on asphalt mixtures
Bambulová, Lucie ; Coufalík, Pavel (referee) ; Hýzl, Petr (advisor)
The bachelor thesis deals with a description of the laboratory properties of aged bituminous binders in relation to permanent deformation. The theoretical part deals with the empirical tests: needle penetration and softening point. There is also explained the procedure and the principle of the MSCR test. In the practical part are evaluated the properties of fifteen tested bituminous binders and based on the results are made two plates which are tested to permanent deformation.
Durability of the waste building materials for subgrade
Lorenc, Daniel ; Hýzl, Petr (referee) ; Stehlík, Dušan (advisor)
The Bacherol thesis is focused on the use of waste building materials to subgrade of the pavement. Examines in detail advantages and disadvantages of this recycled material. Mainly deal with negative properities like water absorption and frost action, and figure out the dependance on the amount of brick parts in waste buildingng material. It practically verifies California bearing ratio, water absorption and rate of frost action of waste building material. A decisive impact on results will have a number of brick parts in recycled material.
Simple design of the improved soils to subgrade pavement
Hurtiš, Maroš ; Hýzl, Petr (referee) ; Stehlík, Dušan (advisor)
This bachelor thesis describes improvement of soils to subgrade pavement. It defines basic expressions, which we are taking in consideration by. Next we are talking about each parameter, which has to be included in final subsoil and which tests are suitable for these parameters. We are decribing California Bearing Ratio in detail and its test. This thesis study context between pH and CBR. Change between these two subjects is caused by addition of a binder. We are practically proving this causes in practical part of bachelor thesis.
Low volume roads
Nováková, Kristýna ; Stehlík, Dušan (referee) ; Hýzl, Petr (advisor)
The aim of this bachelor’s thesis is to process the issue of low volume roads in a theoretical way. Attention will be paid to experiences abroad and in Czech republic as well, considering the structural composition, used methods, materials and costs.
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.
Usage of kevlar fibres in asphalt mixtures
Mazáč, Jan ; Hegr, Zdeněk (referee) ; Hýzl, Petr (advisor)
Diploma thesis deals with topic of using aramid (Kevlar) fibres in road engineering in asphalt mixtures. Theoretical part of thesis is describing characteristics of aramid fibres and their technical usage. Thesis deals with research and application of aramid fibres abroad and also in Czech Republic. Practical part deals with influence of aramid fibres, namely FORTA FI fibres in mixture with modified binder for wearing course. An integral part of this thesis is a description of all methods that were used during the processing of the practical part. In the end of the thesis there are outcomes of tests and theoretical research.
Usage of recycled material in asphalt surface layers
Malá, Markéta ; Komenda, Radek (referee) ; Hýzl, Petr (advisor)
Diploma thesis deals with adding R - material to the wearing asphalt courses, specifically to the SMA 11S. It has two parts – theoretical and practical. The theoretical part describes using R - material in the recycling of roads, different types of recycling and how is this problem handled in the Czech Republic, the practical part deals with the design of three kinds of asphalt mixtures with different added ratios of R – material, describing empirical and functional tests on the bitumen binder and the designed asphalt mixtures and the results of those tests.
