Synchronous Testing Method for Tension and Compression Moduli of Asphalt Mixture under Dynamic and Static Loading States
In order to characterize the ability of tension and compression deformation of asphalt mixture more truly and to improve the test efficiency and scientificity of the tension and compression moduli, the synchronous test method based on the indirect tension test was proposed. The analytical algorithms of the tension and compression resilient moduli of the indirect tension test were derived by integrating the functions of the horizontal and vertical radial strain at the center of a specimen, which was based on Hooke’s law in the two-dimensional stress state and the principle of calculus. The direct tension, unconfined compression, and indirect tension moduli tests were conducted in both dynamic and static loading states, and the test results were compared in different loading states. The research results indicated that the synchronous testing method based on the indirect tension test is effective, and there is a significant difference between the tension and compression moduli of asphalt mixture, and the dynamic resilient modulus from the indirect tension test increases by a power function with the increase of loading frequencies.
