Understanding ASTM D6307: A Comprehensive Guide to the Standard Test Method for Hydrocarbon Traces in Propylene Concentrates
Yes, but with caution. The ignition method burns off the aged binder in RAP as well as the virgin binder. The standard requires that you account for the residual binder content of the RAP through a separate extraction or ignition test on the RAP alone. astm d6307 pdf
This comprehensive article explains everything you need to know about ASTM D6307, why the standard matters, how to legally obtain the PDF, and how to implement its requirements in your asphalt laboratory. Understanding ASTM D6307: A Comprehensive Guide to the
Unlike older solvent-based extraction methods (which use chemicals like trichloroethylene), the ignition method is faster, safer, and more environmentally friendly. The test involves heating a sample of the asphalt mixture in a furnace to a high temperature (typically around 538°C or 1000°F), causing the asphalt binder to burn off, leaving behind the aggregate. The difference in mass before and after ignition represents the asphalt binder content. The ignition method burns off the aged binder
