An extensive research program on asphalt mix fatigue was conducted jointly by the LCPC (French transportation research laboratories) and Scetauroute (French highway engineering agency) between 1990 and 1994. The program included tests on the LCPC circular fatigue test track and a theoretical analysis of the behavior of structures. This article looks into the parts of the program dealing with the fatigue tests and modeling. The aim of this program was to clarify the behavior in the laboratory and on pavements of asphalt mixes differing only in the type of asphalt. Additionally, it involved adding constituents to improve the design method in the case of high-modulus asphalts. On the fatigue test track, more than 7 X 10 to the 6th power load sequences were applied to twelve structures over the course of three experiments. The experimental pavements revealed similar behavior in asphalt concrete of the same thickness, and the good performance of high-modulus materials whenever proper thicknesses were used. The model made it possible to determine a correlation coefficient in connection with rigid materials for the French pavement design method and brought out the value of controlled-force tests.
