The importance of the detection of delamination of Hot Mix Asphalt Pavements at an early stage, will result in a longer service life of the structure. Recently Nondestructive methods have been employed for the detection of delamination.
This study will focus on three of these methods: Impact Echo, Ultrasonic Surface Waves and Impulse response. By using a Finite Element software, the behavior of these three methods was evaluated and then a parametric study was elaborated. The parametric study shows the impact of different variables related to the properties of the flexible pavement and the delamination.
