Bitumen and bituminous binders. Determination of the resistance to hardening under influence of heat and air - RFT method Ingestion-build-117251 BS EN 1422 also guides1 Scope This part of EN 12607 specifies a method for measuring the combined effects of heat and air on a thin moving film of bitumen or bituminous binder, simulating the hardening which most bituminous binders undergo during mixing in an asphalt mixing plant. The method is suitable for other bituminous binders than paving grade bitumen, but the reference temperature might give excessive hardening that does not resemble real conditions during mixing at
