asphalt concrete Ure 3:Enlargement of Figure 2 As a control we also determine resonance frequencies of the specimen. For this kind of measurements the geometry and the boundary conditions of the asphalt concrete must be exactly known. Otherwise it is not possible to find accurate values for the stiffness. With this experiments we are also able to figure out the linear viscoelastic properties of the specimen. To determine the Young's modul and the linear viscoelastic properties we use the following experiment (see Figure 4). A transducer excites longitudinal vibrations in an asphalt concrete bar. We change the frequency of the excitation till the bar vibrates at its resonance mode. We check the mode of the resonance by measuring the displacements of several points along the bar. The supporting wires are placed in the nodes of the oscillation mode. We compare the theoretical resonance frequency with the measurement and determine the Young's moduls of the bar. Figure 4: Vibration of an asphalt concrete ba.
