A substantial amount of experimental data is presented to verify a theoretical solution for predicting the fatigue life of asphalt concrete beams from fracture tests. The theory utilizes the principles of fracture mechanics and covers the full range of loading from low to high. The raw test data extracted from a report by Majidzadeh et al.  include dynamic modulus, ultimate tensile strength, critical stress-intensity factor, and fatigue life of asphalt concrete beams fabricated from over 46 different mixtures, consisting of three types of asphalts, five asphalt contents, three filler asphalt ratios, and several gradations. The fracture and fatigue tests were also conducted on one asphalt concrete mix at temperatures ranging from 16 to 35°C (35 to 95°F). The agreement between theory and experiment is excellent.
