Influence of aged bituminous binder on the properties of polymer modified bitumens
Pecha, Marek ; Koudelka, Tomáš (referee) ; Varaus, Michal (advisor)
This bachelor thesis deals with problematics of polymer modified binders specially designed for production of asphalt mixtures containing Reclaimed Asphalt. These polymer modified binders are referred to in the literature as PMB RC (polymer modified bitumen for recycling). The first part of the thesis is focused on obtaining different types of PMB RC from various european producers. These binders were subsequently tested using empirical tests of asphalt binders for the classification purposes according to ČSN EN 14023. In the next part of the thesis the influence of the addition of aged asphalt binder on the properties of individual PMB RC was assessed. Mixing of binders was done to simulate the production of asphalt mixture in a mixing plant, where the binder of the Reclaimed Asphalt and the freshly added binder are mixed together. An assessment of the effect of the aged binder on PMB RC behavior was also carried out using conventional asphalt binder tests.

Joint sealings of concrete pavements
Doseděl, Jan ; Hýzl, Petr (referee) ; Stehlík, Dušan (advisor)
The findings related to issues of joint sealings of concrete pavements are summarized in this bachelor thesis. The main part of this thesis deals with experimental testing of modified asphalt binder. This asphalt binder was tested at the beginning and at the end of fatigue. The samples of asphalt bitumen were tested by the method of ring and ball, determinativ of needle penetration, elastic recovery and resilince.

Evaluation of properties of PMB containing binder from RAP
Měšťanová, Petra ; Hýzl, Petr (referee) ; Dašek, Ondřej (advisor)
Subject of this diploma thesis is to describe the effect of adding different amount of aged binder recovered from RAP on the change of properties of polymer modified bitumen. The RAP containing unmodified bitumen and the RAP where we can expect bitumen modification are used to recover binder. The binder obtained from RAP is dosed into the virgin binder in amount of 15 %, 30 % and 50 %. The methods of recycling of flexible pavements, extraction and regeneration of asphalt binders, rejuvenating of their properties and methods of empirical and functional laboratory tests are described in the theoretical part. The practical part deals with evaluating and comparison of the results mixed binders properties.

Influence of polymer modified bitumens storage on their properties
Měšťanová, Petra ; Fišer,, Jiří (referee) ; Dašek, Ondřej (advisor)
Subject of this bachelor’s thesis is to describe the influence of long-term storage of polymer modified bitumen at temperature of 180 °C on their properties. The principle of binder modification and test procedure of needle penetration, softening point, elastic recovery and dynamic viscosity in DSR will be explained in the theoretical part. The properties changes of five tested modified binders during storage will be evaluated and compared in the practical part.

Properties of reclaimed bitumens from asphalt mixtures with RAP
Mucha, Ondřej ; Dašek, Ondřej (referee) ; Hýzl, Petr (advisor)
Subject of this diploma thesis is the issue of asphalt mixtures with RA. The theoretical part of the work describes the RA itself, how it is obtained, the requirements according to currently valid standards, the production of asphalt mixture with RA, various options for rejuvenating aged binder, the materials used and the individual testing methods. In the practical section, selected empirical and functional parameters of extracted binders from samples are determined. This part evaluates and compares the results of properties of reclaimed asphalt binders from asphalt mixtures, where aged asphalt binders were rejuvenated by different methods during their production.

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.
