This test is used to determine the tensile creep compliance at different loading times, tensile strength and Poisson’s ratio of hot-mix. The horizontal and vertical deformations are measured near the centre of the specimen using LVDT transducers mounted directly on the specimen. This gives the most accurate results and reduces the chances of operator errors. This configuration has been adopted by many researchers for also determining indirect tensile resilient and dynamic modulus.
