Standard Test Method for Solubility of Asphalt Materials in Trichloroethylene

SCOPE
1.1 This test method covers the determination of the degree of solubility in trichloroethylene of asphalt materials having little or no mineral matter.
Note 1—Use of carbon disulfide, carbon tetrachloride, and benzene has been discontinued in this method because of the safety hazards involved. 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 D 4, D 2318, and D 2764.
1.2 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. Specific precaution statements are given in Section 7.

cooling period in the dessicator, the mass of the crucible containing the
insoluble matter should be determined after a 30 6 5-min cooling period
in the desiccator. Either empty crucibles or crucibles containing insoluble
matter that have remained in a desiccator overnight should be reheated in
an oven for at least 30 min, then allowed to cool for the prescribed period
before the mass is determined.
11. Calculation and Report
11.1 Calculate either the total percentage of insoluble matter
or the percentage of the sample soluble in the solvent used as
follows:
C 2 A
% Insoluble 5 3 100 (1)
S D

B 2 ~C 2 A!
% Soluble 5 3 100 (2)

where:
A 5 mass of crucible and filter,
B 5 mass of sample, and
C 5 mass of crucible, filter and insoluble material.
11.2 For percentages of insoluble less than 1.0, report to the
nearest 0.01 %. For percentages of insoluble 1.0 or more,
