註釋This report presents an evaluation of several test systems for stiffness determination of asphalt-aggregate mixes, including 1) axial resilient stiffness, 2) diametral resilient stiffness, 3) resilient and dynamic flexural stiffness, and 4) dynamic shear stiffness. All of the stiffness test systems were found to be sensitive to mix and test variables, especially to asphalt source, asphalt content, aggregate type, and air-void content. Models are presented to permit estimation of flexural stiffness (and loss-stiffness) from shear stiffness (and loss-stiffness in shear) at 20 deg C and 10 Hz frequency.
