| Significance and Use |
|
3.1?Certain agencies who desire to use, store, or transport emulsified asphalt under less than ideal weather conditions may require that the product remain homogeneous (unbroken) after being subjected to a temperature of ?18 ?C. 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.
