This paper presents testing of fatigue life of asphalt concrete that has been subjected to action of water and frost. Simulation of water and frost action was based on the original AASHTO T283 method and its modification. The original method was modified in such a way that instead of a single freeze-thaw cycle, 50 and 150 cycles were applied. Fatigue life was measured in the indirect tensile fatigue test in the Nottingham asphalt tester (NAT) apparatus. The asphalt concrete specimens were prepared in the laboratory. Some specimens contained liquid adhesive agent (namely fatty amine), and others did not. The detrimental effect of water and frost was clearly identified. The testing procedure results and practical conclusions are presented.
