Bituminous mixtures. Test methods for hot mix asphalt - Determination of the ash content of natural asphalts Ingestion-build-189776 standardize the process of collecting1 Scope This European Standard describes a test method to determine the ash content in natural asphalts (including lake asphalts), binders containing natural asphalts or bitumens. For the method to apply, it is essential that any mineral matter in the binder be finely divided and cannot exceed 45 % by mass.
