Indirect Tension Modulus Test

With this test set-up the Resilient Modulus and Fatigue behaviour of asphalt mixtures can be determined at different temperatures and frequencies.

Indirect Tension Strength and Fatigue Test

With this test set-up an indication of the tensile strength of asphalt mixtures can be measured. The basic idea is to submit a slice of the material under investigation to a compressive force along its vertical axis. This results in a tensile stress along the horizontal axis, which causes splitting failure. With this set up also the Fatigue properties of an asphalt specimen can be measured.
