ASTM D2042-15 rus PDF

Full title and description

Designation: ASTM D2042-15 — Standard Test Method for Solubility of Asphalt Materials in Trichloroethylene. This entry refers to the 2015 ASTM test method (Russian-language PDF/translation available as a stand‑alone product) that describes the laboratory procedure to determine the fraction of asphalt material soluble in trichloroethylene.

Abstract

Provides a short, reproducible laboratory procedure for dissolving asphalt materials in an organic solvent, filtering the insoluble residue, drying and weighing to report percent solubility. Later revisions of the D2042 method (notably the 2022 edition) extended solvent options to include toluene and updated editorial and safety notes.

Scope

This test method covers determination of the degree of solubility in trichloroethylene (and in later editions, also toluene) of asphalt materials that contain little or no mineral matter. The method is not applicable to tars, tar residues, or highly cracked petroleum products; users are referred to other ASTM methods for those materials. The test reports the soluble portion (representing the active cementing constituents) as a percentage of the sample.

Key topics and requirements

• Sample preparation: representative sample of asphalt material with negligible mineral content.
• Solvent selection: trichloroethylene (primary in D2042-15); later editions include toluene as an alternative solvent.
• Dissolution procedure: dissolve sample in solvent under controlled conditions to ensure complete wetting and dissolution of bituminous constituents.
• Filtration: separate insoluble material using a glass-fiber pad or Gooch-type crucible; wash residual solids to remove entrained soluble material.
• Drying and weighing: dry the insoluble residue to constant mass and determine percent soluble by mass difference.
• Limitations and safety: not suitable for tars/very cracked products; solvents are hazardous — follow safety, ventilation, and regulatory precautions described in the standard.

Typical use and users

Laboratories performing quality control and characterization of asphalt binders and paving materials, highway and transportation authorities, pavement materials suppliers, research organizations, and contract testing labs. The method is used for binder characterization, product specification verification, and comparative material studies.

Related standards

Users of D2042 are commonly cross-referenced to other ASTM methods for bituminous materials and solvent-based tests, for example Test Methods D4, D2318, and D2764 (for tars and cracked products) and other pavement/material standards used in binder and residue analysis. Additional related documents and complementary standards are listed in vendor and standards catalogs for D2042.

FAQ

Q: What is this standard?

A: ASTM D2042-15 is the 2015 edition of the Standard Test Method for Solubility of Asphalt Materials in Trichloroethylene — a short laboratory procedure to determine the percent of asphalt soluble in an organic solvent.

Q: What does it cover?

A: It covers sample dissolution in trichloroethylene, separation of insoluble residue by filtration, drying and weighing the residue, and calculation of percent solubility; it excludes tars and highly cracked products (other ASTM methods apply to those materials).

Q: Who typically uses it?

A: Asphalt testing and QC laboratories, DOT/state highway agencies, pavement material manufacturers, and research institutions for binder characterization and specification testing.

Q: Is it current or superseded?

A: The D2042-15 edition is the 2015 version; the method was revised and published as D2042-22 (publication date listed as January 1, 2022) — users requiring the most current procedural text should consult the 2022 edition or the ASTM catalog entry.

Q: Is it part of a series?

A: D2042 is one of several ASTM methods addressing bituminous materials and solvent-based residue/solubility tests; related methods (e.g., D4, D2318, D2764) cover tars and other specific materials and procedures.

Q: What are the key keywords?

A: Asphalt, solubility, trichloroethylene, toluene, binder, Gooch, insoluble residue, pavement materials.
