ASTM D6935-22

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: D6935 − 17 D6935 − 22
Standard Test Method for
Determining Cement Mixing of Emulsified Asphalt
This standard is issued under the fixed designation D6935; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 This test method is intended to be a mixing test used to identify or classify a slow-setting, SS or CSS, type of emulsified
asphalt.
1.2 The values stated in SI units are to be regarded as standard. No other units of measure 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 for the standard.
1.4 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.
1.5 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.

3. Significance and Use
3.1 The result of this test method indicates the ability of a slow-setting emulsified asphalt to mix with a finely divided,
high-surface-area material (high early strength, Type III,III portland cement) without breaking the emulsified asphalt.
This test method is under the jurisdiction of ASTM Committee D04 on Road and Paving Materials and is the direct responsibility of Subcommittee D04.42 on Emulsified
Asphalt Test.

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.
4. Sample Conditioning for Testing
4.1 All emulsified asphalts shall be properly stirred to achieve homogeneity before testing.
4.2 All emulsified asphalts with viscosity testing requirements of 50 °C shall be heated to 50 6 3 °C in the original sample
container in a water bath or oven. The container should be vented to relieve pressure. After the sample reaches 50 6 3 °C, stir the
sample to achieve homogeneity.
4.3 Emulsified asphalts with viscosity testing requirements of 25 °C should be mixed or stirred at 25 6 3 °C in the original sample
container to achieve homogeneity.
NOTE 2—Emulsified asphalts with viscosity testing requirements of 25 °C may be heated and stirred as specified in 4.2, if necessary. In the event the 4.2
method is used, the sample should be cooled to 25 6 3 °C before testing.
