New trends in the field of stone mastic asphalts
Pfeiferová, Magdaléna ; Varaus, Michal (advisor)
The work consists of two parts. The first part is focused on the determination of an anti-skid properties of the test section on Vídenská street. The anti-skid properties will be measured using a pendulum tester and macrotexture will be set at the same time. Microtexture will be measured using a volumetric patch technique. In the second part we will try to gain an initial experience with design and testing of a low noise stone mastic asphalt. We will set basic characteristics and at the same time compare with a standard stone mastic asphalt. For the comparison two various bituminous binders are used. The water sensitivity, resistance against rutting and stiffness moduli are compared.

Evaluation of Selected Properties of Asphalt Mixtures with High Air Void Content
Jakub, Tomáš ; Dašek, Ondřej (referee) ; Šperka, Pavel (advisor)
The bachelor thesis is focused on selected properties of asphalt mixtures with higher air-voids content. The first, theoretical part of the work deals with summary of the available literature. Especially in terms of the distribution of mixtures with higher air-voids content and basic effects of air-voids content behavior of the asphalt mixtures. The second, parctical part of the work deals with determinine properties of two asphalt mixtures, namely: porous asphalt (PA 8) and mastix asphalt with higher air-voids content (SMA NH 8). At first is described used test‘s methods and used materials. Within the work, some tests were modified in order to simulate the effect of frost and salt on asphalt mixtures. An integral part of the practical part is the determintation of water resistence (ITSR), frost and salt of the prepared mixture, their mutual comparison and comparison with existing regulations.
