摘要：

This paper deals with fatigue and complex modulus for three hot mixes. The Brazilian asphalt binders used in this work are classified by penetration grade 10/20, 30/45 and 50/70. It was observed a critical temperature variation in the Cole-Cole plane and in the fatigue test, where the smallest strain for one million cycles occurs at 30 degrees C for the mixture with penetration grade binder 10/20, and at 20 degrees C for the mixture with penetration grade binder 30/45, in relation to the mixtures prepared with conventional penetration grade binder 50/70, in which larger viscous component of the modulus normally occurs at 10 degrees C.
