Standard Specification for Hot-Mixed, Hot-Laid Bituminous Paving Mixtures1 This standard is issued under the fixed designation D ; 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 e indicates an editorial change since the last revision or reapproval. D Specification for Fine Aggregate for Bituminous 1.

Gradings approaching the maximum amount permitted to pass the No. The blend of aggregates and filler, when tested in accordance with Test Method D , shall have a plasticity index of not greater than 4, except that this plasticity requirement shall not apply when the filler material is hydrated lime or hydraulic cement.
The wide difference in the specific gravity of various aggregates, as well as a considerable difference in absorption, results in a comparatively wide range in the limiting amount of bitumen specified.
The amount of bitumen required for a given mixture should be determined by appropriate laboratory testing or on the basis of past experience with similar mixtures, or by a combination of both.
Adequate provisions shall throughout the mixture. At no time during the processing, from be made to keep bitumen aggregate for recycling from being storage to mixing, will temperature of the bitumen be allowed mixed with aggregates or otherwise contaminated.
