Abstract

This paper provides a test protocol for performing creep tests on asphalt mixture beam specimens using the bending beam rheometer, and addresses the issues related to performing this test. First, a detailed sample preparation procedure is presented and the experimental data are provided to assess the consistency of this method. Then, three loading methods are investigated, and results are analysed and compared using statistical tools. Finally, a preliminary investigation on the representative volume element of asphalt mixtures at low temperatures is performed by testing beams of different sizes.
