Modulus and Damping of Asphaltic Concrete Using the Resonant Column

CODEN: GTJODJ

Abstract

A program to determine Young's modulus of asphalt concrete using the resonant column is presented. The equipment is capable of longitudinal and torsional vibrations. The specimens were tested at three temperatures. A copper heating coil mounted inside the apparatus was used to control specimen temperature. The basic properties of the test material are also described. The two major problems of this particular program were the loss of coupling between the test specimen and the apparatus and the failure to effectively reduce spurious machine vibrations at high frequencies. As expected, modulus and damping were functions of temperature.
