Recommendation of RILEM TC 237-SIB on complex Poisson’s ratio characterization of bituminous mixtures

This recommendation describes how to characterize the isotropic three-dimensional linear viscoelastic behaviour of bituminous mixtures through the simultaneous measurement of the complex Young’s modulus (E ) and the complex Poisson’s ratio (m ). The guidelines given herein are based on the results of a RILEM round robin test organized by the RILEM Technical Committee 237-SIB ‘‘Testing and characterization of sustainable innovative bituminous materials and systems’’ and focus on the testing procedure, measurement setup, data analysis and presentation of results. Indications for the preparation of a tests report are also given.
