ASTM D6935-22

Standard Test Method for Determining Cement Mixing of Emulsified Asphalt

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 portland cement) without breaking the emulsified asphalt.
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 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.
