Complex Bituminous Binders, Are Current Test Methods Suitable for?

The asphalt industry is constantly working to enhance the performances of materials, introducing innovative and more sustainable solutions. In this context, incorporation such as additives, polymers, used improve properties neat bitumen. This leads even complex bituminous binders, raising question, are current specifications test methods appropriate for materials? To deal with this, RILEM Technical Committee 272-PIM ‘Phase Interphase behaviour Materials’ its Task Group TG1 looking at efficiency various binders an extensive inter-laboratory program 17 laboratories. It includes seven different two bitumen, polymer modified bitumen three liquid emphasising on compositional physical changes conditions. focus low temperature; while a complementary experimental encompasses well testing intermediate high temperatures. outcomes work will provide indications how robust binder characterisation techniques establish technical recommendations future specially designed binders. Some first results presented hereby.
