The dynamic stiffness modulus measurement is to determine the relationship between maximum applied stress and maximum strain response performed by measuring the displacement of tested system. The test is conducted using MTS Landmark servohydraulic testing system of 100 kN, special grips for fixing the sample and RTSS videoextensometer in accordance with modified method:
EN 12697-26 Bituminous mixtures – Test methods – Part 26: Stiffness
As part of the testing of the PM&VL7 research line, Flex&Robust composites were examined.
