For mixes prepared with cutback asphalt, introduce the mixing blade in the mixing bowl and determine the total weight of the mix components plus bowl and blade before proceeding with mixing. NOTE 1—Uncompacted mixtures are used for determination of theoretical maximum specific gravity. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. Charge the mixing container with the heated aggregate and dry mix thoroughly approximately 5 s with scoop or spoon.

Significance and Use 3. In this original Marshall procedure, no mechanical device of any kind shall be used to restrict the handle of the hammer in the vertical position during compaction.

This standard is not included in any packages. Uncompacted mixtures are astk for determination of theoretical maximum specific gravity. As the voice of the U.

Density and voids analysis are also conducted on specimens for mixture design and evaluation of field compaction. Mix the aggregate and bituminous material rapidly until thoroughly coated for approxi- 5. This standard is subject to revision d696 any time by the responsible technical committee and must be reviewed every five years and if not revised, either reapproved or withdrawn.

The quality of the results produced by this practice are dependent on the competence of the personnel r6926 the procedure and the capability, calibration, and maintenance of the equipment used.

The user should contact the manufacturer to establish appropriate mixing and compaction temperature ranges. Any cut aggregate can be removed.

For Marshall stability, and flow determination according to Practice D, use only those replicate specimens which have bulk specific gravities within These notes and footnotes excluding those in tables and figures shall not be considered aatm requirements of the standard.

Dial thermometer may exhibit inaccuracies due to frequently use or mishandling. Heating should only be long enough to achieve desired compaction temperature. Asym following types of hammer arrangements are included in this ast The compaction temperature for a cutback asphalt mixture is selected using a compositional chart of viscosity versus percent solvent for that cutback asphalt.

Best comparative results will be obtained by compacting all specimens with the same hammer and with no other hammers operating. Already Subscribed to this document.

A fan can be used to facilitate cooling. The following types of hammer arrangements are included in this practice: Agencies that meet the criteria of Specification D are generally considered capable of competent and objective testing, sampling, inspection, etc.

At this point, the mixture temperature shall be within the limits of the mixing temperature established in 5.
