...Xiaoxia Zhen; Zhuojie Zhang; Rui Rao; Wei Chen For long-span steel bridges, the contact states between the pavement and the steel decks change significantly during the operation stage. Different interlayer contact states have different effects on the viscoelastic mechanical properties...

...Seong-Hyeok Lee; Hai V. Vo; Dae-Wook Park In this study, the full-scale testing of asphalt track and numerical simulation using the viscoelastic material property of asphalt mixtures under cyclic loading was investigated. Dynamic modulus tests were conducted to characterize the linear viscoelastic...

.... Viscoelastic response models of the asphalt concrete were properly established by using the Prony series. The developed response models were used in finite element simulations on the conductive asphalt pavement. The model of pavement embedded with different types of tubes was subjected to moving load. When...

...B. Shane Underwood; Y. Richard Kim Asphalt concrete (AC) is a heterogeneous material affected by viscoelastic and viscoplastic processes, as well as by damage and localized irregularities in the material fabric. However, under specific strain regimens, certain of these mechanisms are less active...

... were subjected to tensile creep to investigate the effect of different thermal treatment conditions on their viscoelastic response over a 1-year period. Results from the experimental study showed the necessity to perform tensile creep tests rather that direct tensile strength tests to predict the long...

...SA Lippert; EM Rang; MJ Grimm The wave-in-a-tube method allows for the estimation of material properties of gel-like, viscoelastic materials utilizing only a pair of matched ultrasonic pressure transducers. To employ this technique, a sample tube must be manufactured that (1) has an inside diameter...
