Evaluation of properties of clear and pigmented asphalt binders
Kamanová, Monika ; Machalla, Michael (referee) ; Dašek, Ondřej (advisor)
The Bachelor thesis subject is comparison of the chosen parameters of clear asphalt binder with pigmented asphalt binder. The theoretical part explains parameters of asphalt binders and improving their properties after using additives. The second part is explaining methods and test results. The empirical tests (needle penetration, softening point, breaking point) and performance tests in dynamic shear rheometer and bending beam rheometer are used for comparison of binders properties. In the conclusion the laboratory aging of asphalt binders is described by RTFOT and RTFOT + PAV method.

Influence of aging on selected properties of asphalt binders
Rimel, Jindřich ; Dašek, Ondřej (referee) ; Hýzl, Petr (advisor)
In this bachelor’s thesis, the properties of four asphalt binders with different degree of modification are compared. The influence of aging on their properties is examined. In the theoretical part, the types of aging, their impact on binders, basic laboratory methods of aging and the details of performed tests are explained. In the practical part, the results of tests are evaluated and the change of properties before and after aging are compared.

Influence of virgin bitumen on the properties of polymer modified bitumens
Kamanová, Monika ; Koudelka, Tomáš (referee) ; Dašek, Ondřej (advisor)
The diploma thesis describes the influence of the used input paving bitumen on the properties of the produced polymer modified bitumen. The theoretical part explains parameters of asphalt binders and improving their properties after using modifying additives. The second part is explaining methods and test results. The empirical tests (needle penetration, softening point, breaking point) and performance tests in dynamic shear rheometer and bending beam rheometer are used for comparison of binders properties. In the conclusion the laboratory aging of asphalt binders is described by RTFOT and RTFOT+PAV method.

Properties of Polymer Modified Bitumens with Addition of Aged Rap Binder
Sachr, Jiří
The aim of this paper is to describe the effect of adding different amounts of aged binder recovered from RAP on the change in properties of polymer modified bitumen 45/80-65 and polymer modified bitumen referred to as 45/80 RC, which is a binder suitable for cementing asphalt mixtures containing high amounts of RAP. It is also an effort to evaluate the changes in properties of these blended asphalt binders caused by laboratory simulation of aging by rolling thin film oven test (RTFOT) and pressure aging vessel (PAV). Both RAP containing unmodified asphalt binder and RAP obtained from an asphalt mixture that can be assumed to contain polymer modified bitumen are used to recover the aged binders. The aged binder obtained from the RAP is dosed into the fresh binder at 0 %, 15 %, 30 % and 50 %.
