Stiffness of Bituminous Mixtures Using Ultrasonic Wave Propagation
Wave propagation tests were performed on several specimens of bituminous mixes. Back analysis is made within the framework of linear viscoelastic materials to obtain dynamic moduli. Comparison with moduli obtained from traditional cyclic tension-compression complex modulus test, shows that dynamic tests and cyclic tests results fit very well. A unique master curve is obtained and the time-temperature superposition is validated for very high frequencies (several 10 kHz). Simulation with the model developed at University of Lyon, ENTPE laboratory (2S2P1D) confirms the ability of this model to cover the wide frequency and temperature range. Furthermore, moduli obtained in different directions from dynamic (wave propagation) tests, reveal that different compaction techniques create different types of anisotropy.
