ASTM D2042 – Standard Test Method for Solubility of Asphalt Materials in Trichloroethylene or Toluene
Description:
Significance and Use
4.1 This test method is a measure of the solubility of asphalt in trichloroethylene or toluene solvent. The portion that is soluble in the solvent represents the active cementing constituents.
NOTE 2: 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 D3666 are generally considered capable of competent and objective testing, sampling, inspection, etc. Users of this standard are cautioned that compliance with Specification D3666 alone does not completely ensure reliable results. Reliable results depend on many factors; following the suggestions of Specification D3666 or some similar acceptable guideline provides a means of evaluating and controlling some of these factors.
Scope
1.1 This test method covers the determination of the degree of solubility in trichloroethylene or toluene of asphalt materials having little or no mineral matter.
NOTE 1: This method is not applicable to tars and their distillation residues or highly cracked petroleum products. For methods covering tars, pitches, and other highly cracked petroleum products, and the use of other solvents, see Test Methods D4, D2318, and D2764.
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.
