ASTM D5546−09 Standard Test Method for Solubility of Asphalt Binders in Toluene by Centrifuge

ASTM D5546−09 Standard Test Method for Solubility of Asphalt Binders in Toluene by Centrifuge

Scope
1.1 This test method covers determination of the degree of solubility of asphalt binders in toluene using centrifugal separation.

The method is an alternative to Test Method D2042, and may be preferable to Test Method D2042 when testing modified asphalt binders.

1.2 The values stated in SI units are to be regarded as standard.

No other units of measurement are included in this standard.

1.3 The text of this standard references notes and footnotes which provide explanatory material.

These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.

1.4 A complete precision statement for this standard has not been developed at this time.

Therefore, this standard should not be used for acceptance or rejection of a material for purchasing purposes.

Significance and Use
4.1 This test method is a measure of the solubility of polymer-modified asphalt in toluene.

The portion that is soluble in toluene represents the active cementing constituents.

Additional tests to characterize the insoluble residue may be conducted.

Such tests might include infrared spectroscopy, microscopy, ash content, and so forth.
