Abstract


The study of the fatigue behavior for asphalt mixtures has a particular importance both to estimate the degradation that can occur during service period in the asphalt layer under external loads (traffic, climate) and to consider the fatigue laws taking into account in asphalt pavement design.
European Standard adopted in our country, SR EN 13108: 20 stipulate some tests to determine fatigue resistance of asphalt mixtures, including 4PB PR test (four-point bending test on pris-matic samples).
This paper has the goal to emphasize the results (fatigue resistance and stiffness) obtained in Road Laboratory of Technical University of Civil Engineering on some types of asphalt mix-tures with PMB binder (asphalt mixtures used in Romania). The conclusions will be presented as comparative charts.
