Dynamic modulus and phase angle prediction of laboratory aged asphalt mixtures
Construction and Building Materials, 2018Performance of asphalt mixture is highly influenced by oxidative aging. A considerable amount of research has been dedicated to study the aging process of asphalt binder, while the effect of other contents of the mixture on aging characteristic, such as ...

Dynamic Shear Modulus of Isotropic Elastomers
Macromolecules, 2004We have investigated the dynamic mechanical behavior of two cross-linked polymer networks with very different topologies: one made of backbones randomly linked along their length; the other with fixed-length strands uniformly cross-linked at their ends. The samples were analyzed using oscillatory shear, at very small strains corresponding to the linear

Dynamic modulus and damping in graphite composites
Polymer Engineering & Science, 1973AbstractBars made from graphite reinforced resin were impact loaded and foil strain gages were used to determine the characteristics of the stress wave as it propagated along the length of the specimen. Assuming one dimensional wave theory to be valid, values for the dynamic moduli were determined and these were compared to static values obtained from ...

Dynamic Modulus for Reinforced Concrete Beams
Journal of Structural Engineering, 1984The modulus of elasticity of concrete given by ACI Code 318-83 is thought of as secant modulus under static loads. It is more appropriate to use modulus of elasticity of concrete measured by a dynamic system, where dynamic loads are involved. The transverse vibration and elastic wave propagation methods are used to get the dynamic elastic modulus.

Dynamic Modulus of Asphalt Treated Mixtures
Road Pavement Material Characterization and Rehabilitation, 2009This paper presents the results of laboratory testing to determine the complex modulus of asphalt treated mixtures. Laboratory tests were performed on two different asphalt treated mixtures from Qingyuan. Testing was performed at six temperatures and five frequencies.

Precision Analysis of Sigmoidal Master Curve Model for Dynamic Modulus of Asphalt Mixtures
Journal of materials in civil engineering, 2018The sigmoidal master curve model can be used to obtain the value of dynamic modulus of asphalt mixtures at a high or low temperature, which cannot be obtained directly from laboratory tests...
