5.1 Asphalt prisms compacted with the shear box compactor can be used to obtain specimens for further testing, including bulk specific gravity following Test Methods D6752/D6752M and D2726/D2726M; dynamic modulus following AASHTO T 342; dynamic modulus, flow number, and flow time following AASHTO T 378; and fatigue performance characteristics following AASHTO T 321.

5.2 Specimens to perform other standard tests could also be obtained, as long as their volume is contained within the volume of a prism having maximum width, length, and height (W × L × H) of 150 mm, 450 mm, and 185 mm, respectively. The maximum prism height depends on the mix type, the target air voids, and the equipment limitations.

Note 1: The aggregate orientation in the samples produced by this method may be different from samples produced by other laboratory compaction methods. This should be considered when comparing mechanical test results from different compaction methods.

Note 2: 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.
