| Significance and Use | ||||||||||
|
3.1?This test method is used to determine the grading of aggregates extracted from asphalt mixtures. The results are used to determine compliance of the particle size distribution with applicable specifications requirements, and to provide necessary data for control of the production of various aggregates to be used in 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.
