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.

Low-temperature behavior of asphalt binders
Čumíčková, Markéta ; Šperka, Pavel (referee) ; Stehlík, Dušan (advisor)
The work is focused on low-temperature behavior of specimens of asphalt binders and polymer modified bitumens. In the theoretical part, the principles and procedures of tests are simply described: Needle Penetration, Softening Point, Bending Beam Rheometer and Fraass breaking point. In the practical part, results of tests are demonstrated to graphs. The aim of thesis is to determine the correlation between tests.

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.
