Asphalt Extraction for Blending Curve (D-6847, T319)

This test method covers a procedure for the extraction and recovery of asphalt binder from asphalt mixtures-both HMA (hot mix asphalt) and RAP (reclaimed/recycled asphalt pavement)—having a minimal effect on the physical properties of the asphalt binder recovered. It is primarily intended for use when the physical properties of the recovered asphalt are to be determined. It can also be used to determine the quantity of asphalt binder in the HMA or RAP. Recovered aggregate may be used for sieve analysis. This may also be accomplished through Test Methods D 2172
