In this bachelor's thesis were suggested two kinds of asphalt mixtures. The first one contains conventional asphalt binder and the second one Crumb Rubber modified Bitumen. The aim of this thesis is a comparison of stiffness and fatigue characteristics of these two mixtures by two-point bending test on truncated wedges. There will be also an evaluation of the impact of an asphalt addition of the Crumb Rubber modified Bitumen in one of these mixtures.
