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

Abstract

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 ( $$\nu^{*}$$ ). 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.
