Your comments are invited either for revision of this standard or for additional standards and should be asgm to ASTM International Headquarters. Permission rights to photocopy the standard may also be secured from the ASTM website www. Density and voids analysis are also conducted on specimens for mixture design and evaluation of field compaction. D — 10 hammer by hand, as nearly perpendicular as possible to the base of the mold assembly during compaction.

Density and void s6926 are also conducted on specimens for mixture design and evaluation of field compaction. You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server. Standards Subsctiption may be the perfect solution.

In ast, 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. Please help us to share our service with your friends.

Specimens should be accepted or rejected for further testing based on requirements of the criteria being applied. This standard is subject to revision at any time by the responsible technical committee and must be reviewed atsm five years and if not revised, either reapproved or withdrawn.

Any cut aggregate can be removed. We have no amendments or corrections for this standard.

ASTM D6926-10

In preparation for heating to compaction temperature the material should be warmed and worked until a loose mixture condition is obtained. 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 user to establish the specific required number of blows to be used for compaction of the specimen in relation to the field. Please first log in with a verified email before subscribing to alerts. NOTE 4—Standardization practices specified in Specification D are recommended for the thermometer used in this test method. These notes and footnotes excluding those in tables and figures shall not be considered as requirements of the standard.

Cooling specimens in the mold can be facilitated by immersion in cold water. As the voice of the U. Add to Alert PDF. At this point, the mixture temperature shall be within the limits of the mixing temperature established in 5.

Mechanical hammers are available that operate at 1 nominal 55 blows per minute or 2 equal to or greater than 75 blows per minute. Dial thermometer may exhibit inaccuracies due to frequently use or mishandling.

Your Alert Profile lists the documents that will be monitored. Last previous edition approved in as D—04 DOI: The following types of hammer arrangements are included in this practice: NOTE 1—Uncompacted mixtures are used for determination of theoretical maximum specific gravity.

Best comparative results will be obtained by compacting all specimens with the same hammer and with no other hammers operating. A fan d66926 be used to facilitate cooling. Place the covered metal containers in a ventilated oven at the temperature established in 5. Carefully transfer specimens to a smooth, flat surface wstm allow to cool at room temperature this may be overnight. Work Item s – proposed revisions of this standard. This standard is also available to be included in Standards Subscriptions.

Heating should only qstm long enough to achieve desired compaction temperature. We need your help to maintenance this website. Already Subscribed to zstm document. Historical Version s – view previous versions of standard. A typical mechanical hammer is shown in Fig. Thank you for interesting in our services.

NOTE 7—Hammer shaft should be clean and lightly oiled. Place the mixture in the mold, spade the mixture vigorously with a heated spatula or trowel 15 times around the perimeter and 10 times over the interior. The holders shall hold the compaction mold, collar, and base plate securely in position during compaction of the specimen.

Uncompacted mixtures are used for determination of theoretical maximum specific gravity.
