Agencies that meet the criteria of Specification D are generally considered capable of competent and objective testing, sampling, inspection, etc. The steel disk is used for extracting compacted specimens from molds with the use of the mold collar. NOTE 1—Uncompacted mixtures are used for determination of theoretical maximum specific gravity.

Originally approved in Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. Stability of reheated and recompacted mixtures from existing pavements is likely to be higher than the original mixture due to in service hardening of the binder. Temperature of the mixture immediately prior to compaction shall be within the limits of the compaction temperature established in 5.

The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. At this point, the mixture temperature shall be within the limits of the mixing temperature established in 5. NOTE 7—Hammer shaft should be clean and lightly oiled.

Add to Alert PDF. Mechanical hammers are available that operate at 1 nominal 55 blows per minute or 2 equal to or greater than 75 blows per minute.

Allow the specimen to cool sufficiently to prevent damage and extract the specimen from the mold.

Density and voids analysis are also conducted on specimens for mixture design and evaluation of field compaction. Permission rights to photocopy the standard may also be secured from the ASTM website www. Reliable results depend on many factors; following the suggestions of Specification D or some similar acceptable guideline provides a means of evaluating and controlling some of f6926 factors. It is recommended that the standardization of dial thermometers be conducted more frequently by a comparison to a reference thermometric device of equal or greater readability at a temperature within the range of intended use.

This standard is also available to be included in Standards Subscriptions. Subscription pricing is determined by: Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.

However, care should be exercised to prevent mix loss. The reheating process will have only minor influence on binder hardening. Place another piece of nonabsorbent paper cut to fit on top of the mix. The steel cap shall be firmly xstm to the post.

The compaction temperature for a cutback asphalt mixture is selected using a compositional chart of viscosity versus percent solvent for that cutback asphalt. It is up to the owner or specifier to establish the specific required number of blows to be used for compaction of the specimen in relation to the field. Your Alert Profile lists the documents that will be monitored.

ASTM D – 10 Standard Practice for Preparation of Bituminous Specimens Using Marshall Apparatus

D — 10 hammer awtm hand, as nearly perpendicular as possible to the base of the mold assembly during compaction. Standards Subsctiption may be the perfect solution. After compaction, remove the collar and base plate. 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. Current edition approved June 15, A metal pan or bowl of sufficient capacity for hand mixing may also be used.

Dial thermometer may exhibit inaccuracies due to frequently use or mishandling. Please first log in with a verified email before subscribing to alerts. These notes and footnotes excluding those in tables and figures shall not be considered as requirements of the standard.

This standard is not included in any packages. If the document is revised or amended, you will be notified by email. Mechanical hammers are available that operate at 1 nominal 55 blows per minute and 2 equal to or greater than 75 blows per minute.
