ASTM D6627/D6627M-22

Standard Test Method for Determination of a Volatile Distillate Fraction of Cold Asphalt Mixtures

SIGNIFICANCE AND USE
3.1 This test method is used for determining the amount of a temperature-specific volatile distillate fraction in cold mix asphalt mixtures.
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 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 those factors.
SCOPE
1.1 This test method covers the determination, by direct measurement, of the ambient to 260 °C [500 °F] volatile distillate fraction of cold mix asphalt mixtures.  
1.2 A precision and bias statement for this test method has not been developed since this test method is used for research purposes or information only. Therefore this test method should not be used for acceptance or rejection of a material for purchasing purposes.  
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.  
1.4 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.  
1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Overview

ASTM D6627/D6627M-22, titled "Standard Test Method for Determination of a Volatile Distillate Fraction of Cold Asphalt Mixtures," is an international standard developed by ASTM International. This test method outlines procedures to measure the quantity of volatile distillate fractions in cold mix asphalt mixtures at temperatures up to 260 °C (500 °F). It is specifically intended for research or informational use and not for the acceptance or rejection of material for purchase contracts.

This standard plays an important role in evaluating cold mix asphalt mixtures, assessing their volatile content, and understanding their performance characteristics during research and development. Accurate determination of volatile distillate fractions can help inform production processes, quality control, and performance analysis for road and paving materials.

Key Topics

• Scope and Applicability

  • Measures volatile distillate fractions in cold mix asphalt mixtures between ambient temperature and 260 °C (500 °F).
  • Applies to both SI and inch-pound units, which must be used independently.
  • Intended for research or informational analysis only – not for material acceptance.

• Significance

  • Provides a direct measurement method for quantifying temperature-specific volatile distillate content.
  • Results are dependent on both personnel competency and proper calibration and maintenance of testing equipment.
  • Highlights the importance of using agencies that meet minimum testing and inspection requirements (e.g., ASTM D3666).

• Testing Apparatus

  • Specifies the use of specialized equipment such as cylindrical metal stills, water-cooled condensers, collection flasks, and precision balances.
  • Utilizes controlled heating devices and accurate thermometers compliant with relevant ASTM guides.

• Procedure

  • Involves sampling, preparation, distillation, and measurement of collected volatile distillates.
  • Requires careful attention to sampling methods and result calculations for accuracy and repeatability.

• Safety and Compliance

  • Mandates that users establish appropriate safety, health, and environmental practices.
  • Reminds users to consider regulatory limitations before implementing the method.

Applications

The ASTM D6627/D6627M-22 standard is primarily used by:

• Research Laboratories: To investigate the volatile content of cold mix asphalts and develop improved formulations.
• Quality Control Departments: To obtain informational data on batch-to-batch consistency during mix development and production trials.
• Pavement Engineering Groups: To study the influence of volatiles on the performance characteristics of cold mix asphalt.
• Testing Agencies: For the non-contractual evaluation of materials as part of broader material assessment protocols.

Key benefits of applying this standard include:

• Gaining insight into the composition and performance properties of cold asphalt mixtures.
• Informing developmental efforts to optimize additive and binder formulations.
• Providing comparative data for innovation and research on cold mix technology.

Related Standards

ASTM D6627/D6627M-22 is supported by and references several additional ASTM standards critical to the evaluation of asphalt mixtures:

• ASTM D244 – Test Methods and Practices for Emulsified Asphalts
• ASTM D979/D979M – Practice for Sampling Asphalt Mixtures
• ASTM D1461 – Test Method for Moisture or Volatile Distillates in Asphalt Mixtures
• ASTM D3666 – Specification for Minimum Requirements for Agencies Testing and Inspecting Road and Paving Materials
• ASTM D4753 – Guide for Evaluating, Selecting, and Specifying Balances and Standard Masses in Testing
• ASTM D6997 – Test Method for Distillation of Emulsified Asphalt

Summary

Using ASTM D6627/D6627M-22 ensures a standardized approach for determining volatile fractions in cold mix asphalt mixtures. While not suitable for material acceptance, its value lies in research, quality control, and the development of improved paving materials. Adherence to referenced standards and proper methodology maximizes the reliability and usefulness of results, supporting innovation in road construction and maintenance practices.
