The deformational properties and fatigue of asphalt courses are conditional for the design and assessment of semi-rigid and flexible pavements. The term Functional conditions includes properties of asphalt mixtures which are defined by various tests (fatigue test, rutting test, triaxial test). It is possible to use several types of tests to measure fatigue and complex modulus, but in our laboratory was carried out the Two-point Bending Test on trapezoid-shaped samples which was supplemented

The tests have shown a positive impact of additives (ground rubber, hydrate lime component) on the results of these mixtures. This article is focused on assessment of deformational properties and fatigue of selected types of asphalt mixtures.
