Resistance of asphalt binder and asphalt mixture against deformation
Dubšíková, Karolína ; Coufalík, Pavel (referee) ; Dašek, Ondřej (advisor)
Subject of this bachelor´s thesis is to describe laboratory properties of asphalt binders in relation to permanent deformation. The principle and procedure of empirical tests needle penetration and softening point will be explained in the theoretical part. The principle and procedure of MSCR test will be also described. The properties of four asphalt binders will be evaluated in practical part. These binders will be used for production of asphalt mixtures, which will be subjected to wheel tracking test and their results will be compared.

Adhesion of bituminous binders to aggregate
Vlk, Petr ; Hýzl, Petr (referee) ; Varaus, Michal (advisor)
In 2005 the revised European standard 12697-11:2005 [1] was introduced offering a choice of three different methods. The static method described in part B has some similarities with the replaced Swiss standard for the determination of the affinity between bitumen and aggregates [2] and Czech standard for adhesions of asfalt binder to aggregates ČSN 73 6161 [3]. The result of this study is to compare the static method described in the [3] and a draft changes by Swiss research project [4] with the current revision of the European Standard 12697-11: 2005.

Force ductility of asphalt binders
Smolka, Zdeněk ; Coufalík, Pavel (referee) ; Dašek, Ondřej (advisor)
The bachelor thesis describes a laboratory characteristics of bituminous binders. There will be described the principle and results of laboratory tests, needle penetration, softening point by ring and ball and force ductility. The tests will be performed on samples of the bituminous binders with different degrees of modification.

Cold asphalt mixtures
Spáčil, Petr ; Hýzl, Petr (referee) ; Dašek, Ondřej (advisor)
The bachelor thesis is divided into theoretical and practical part. The theoretical part consists of explanation of the problem. The thesis includes definitions as Bitumen, Asphalt Mixture, Asphalt Binder, Cut-back Bitumen and Viscosity. The practical part is focused mainly on the description of the test methods used on Asphalt Binders and Mixtures which were intended for repairs. It describes differences between used Asphalt Binders and explains and describes other used materials. The practical part compares the mixtures of different Cut-back Bitumen. It describes the production process and project of Cut-back bitumen mixture, the production process of individual test solids and compares the differences with hot made asphalt mixture. It also describes the analysis of volumetric, mechanical-physical and funcional tests in purpose of evaluating the differences between standard Cut-back Bitumen and new biofluxed asphalt binder.

Resistance of bituminous binder to ageing
Rous, Vojtěch ; Frýbort, David (referee) ; Kudrna, Jan (advisor)
Asphalt binder ageing and experiences with various ageing methods from abroad are described in this thesis. The practical part deals with the RTFOT aging and with the influence of the duration of this test. The comparison of test results is conducted before and after the aging by values of needle penetration, elastic recovery, softening point and resilience tests are evaluated and compared.

Coarse graded asphalt mixtures
Mucha, Ondřej ; Dašek, Ondřej (referee) ; Hýzl, Petr (advisor)
The bachelor’s thesis is focused on asphalt mixtures that contain coarser aggregates than currently allowed by technical regulations in the Czech Republic. The introductory part of the work describes the composition of asphalt mixtures, their division and use. Further deals with foreign experience with these types of asphalt mixtures and their use in the surrounding European countries and in the United States of America. The aim of this work is to obtain a theoretical overview of knowledge about coarse graded asphalt mixtures from foreign sources and research.
