Permission rights to photocopy the standard may also be secured from the ASTM website www. For asphalt cements and tar mixtures, put the sstm into metal containers and cover. Allow the specimen to cool sufficiently to prevent damage and extract the specimen from the mold. Density and void analysis are also conducted on specimens for mixture design and evaluation of field compaction. Armored-glass or dial-type thermometers with metal stems are recommended.

An example of a viscosity temperature chart is given in Fig. Users of this practice are cautioned that compliance with Specification D alone does not completely ensure reliable results.

Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. The steel cap shall be firmly fastened to the post. D692, care should be exercised to prevent mix loss. ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned asym this standard. The steel disk is used for extracting compacted specimens from molds with the use of the mold collar. Please help us to share our service with your friends.

After cooling, separate the aggregates by dry-sieving into the desired size fractions. At d69926 point, the mixture temperature shall be within the limits of the mixing temperature established in 5.

Carefully transfer specimens to a smooth, flat surface and allow to cool at room temperature this may be overnight. This method must be used as a referee method. Best comparative results will be obtained by compacting all specimens with the same hammer and with no other hammers operating. You may delete a document from your Alert Profile at any time. 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.


Place the covered metal containers in a ventilated oven at the temperature established in 5. 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 those factors.

Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

ASTM D – 04 Standard Practice for Preparation of Bituminous Specimens Using Marshall Apparatus

Suitable shields, baffle ast, or asym baths shall be used on the surfaces of the hot plates to minimize localized overheating. Form a crater in the dry blended aggregate and weigh the required amount of bituminous material at mixing temperature into the mixture. D — 10 Standard Practice for Preparation of Bituminous Specimens Using Marshall Apparatus1 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.

NOTE 1—Uncompacted mixtures are used for determination of theoretical maximum specific gravity. Please fill this form, we will try to respond as soon as possible. You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server.

Any suitable extraction device such as a hydraulic jack apparatus or a lever arm device may be d69226, provided the specimens are not deformed during the extraction d69926. Care must be exercised to prevent loss of the mix during mixing and subsequent handling.


Significance and D6296 3. Cooling specimens in the mold can be facilitated by immersion in cold water. These notes and footnotes excluding those in tables and figures shall not be considered as requirements of the standard.

ASTM D6926-10

The quality of the results produced by this practice are dependent on the competence of the personnel performing the procedure aatm the capability, calibration, and maintenance of the equipment used. Any cut aggregate can be removed. Apply the same number of compaction blows to the face of the reversed specimen. Add to Alert PDF. Place a piece of nonabsorbent paper, cut to size, in the bottom of the mold before the mixture is introduced.

Density and voids analysis are also conducted on specimens for mixture design and evaluation of field compaction. Dial thermometer may exhibit inaccuracies due to frequently use or mishandling. Standards Subsctiption may be the perfect solution. Place aggregate batches in containers on a hot plate or in an oven and heat to v6926 temperature above but not exceeding the mixing temperature established in 5.

NOTE 7—Hammer shaft should be clean and lightly oiled. Place another piece of nonabsorbent paper cut to fit on top of the mix. A number in parentheses indicates the year of last reapproval. Stability of reheated and recompacted mixtures from f6926 pavements is likely to be higher than the original mixture due to in service hardening of the binder. Specimens should be accepted or rejected for further testing based on requirements of the criteria being applied.

D — 10 hammer by hand, as nearly perpendicular as possible to the base of the mold assembly during compaction. NOTE 4—Standardization practices specified in Specification D are recommended for the thermometer used in this test method.
