    Significance and Use

    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.

    Note 1—The quality of the results produced by this standard are dependent on the competence of the personnel performing the procedure and the capability, calibration, and maintenance of the equipment used. Agencies that meet the criteria of Specification D 3666 are generally considered capable of competent and objective testing/sampling/inspection/etc. Users of this standard are cautioned that compliance with Specification D 3666 alone does not completely assure reliable results. Reliable results depend on many factors; following the suggestions of Specification D 3666 or some similar acceptable guideline provides a means of evaluating and controlling some of these factors.

    1. 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 D 2042, and may be preferable to Test Method D 2042 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.

    1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
