Use of ultrasonic pulse velocity (UPV) for assessment of HMA mixtures behavior



Non-destructive methods are nowadays widely used to evaluate the performance of structures and infrastructures, including pavements. In this paper, Ultrasonic Pulse Velocity (UPV) test is investigated for evaluation of the behavior of Hot Mix Asphalt (HMA) mixtures. The effect of different mixtures parameters, including gradation, bitumen and filler contents are studied by means of indirect computation of Elastic modulus of HMA from UPV test and its comparison with experimentally derived Stiffness modulus values from Indirect Stiffness Modulus (ITSM) test.
