ASTM D – 04 Standard Practice for Preparation of Bituminous Specimens Using Marshall Apparatus
The holders shall hold the compaction mold, collar, and base plate securely in position during compaction of the specimen. It is up asstm 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. NOTE 2—Manual compaction hammers should be equipped with a finger safety guard.
Any suitable extraction device such as a hydraulic jack apparatus or a lever arm device may be used, provided the specimens are not deformed during the extraction process. The values given in parentheses asmt mathematical conversions to SI units that are provided for information only and are not considered standard. An example of a viscosity temperature chart is given in Fig. There may or may not be a constant surcharge on top of the hammer handle. Armored-glass or dial-type thermometers with metal stems are recommended.
A number in parentheses indicates the year of last reapproval.
Thank you for interesting in our services. After compaction, remove the collar and base plate. Specimens should be accepted or rejected for further testing based on requirements of the criteria being applied. Permission rights to photocopy the standard may also be secured from the ASTM website www. The ashm assembly shall be installed so that the post is plumb and the cap is level.
Please first verify your email before subscribing to alerts. Specimen mold-holders of d9626 compactors are not necessarily centered. Density and voids analysis are also conducted on specimens for mixture design and evaluation of field compaction. After cooling, separate the aggregates by dry-sieving into the desired size fractions.
Care must be exercised to prevent loss of the mix during mixing and subsequent handling. A metal pan or bowl of sufficient capacity for hand mixing may also be used.
As the voice of the U. Best comparative results will be obtained by compacting all specimens with the same hammer and with no other hammers operating. Carefully transfer specimens to a smooth, flat surface and allow to cool at room temperature this may be overnight. However, care should be exercised to prevent mix loss. Apply the same number of compaction blows to the face of the reversed specimen. For mixes prepared with cutback asphalt, introduce the mixing asgm in the mixing bowl and determine the total weight of the 6d926 components plus bowl and blade before proceeding with mixing.
We are a non-profit group that run this website to share documents. Work Item s – proposed revisions of this standard. The steel cap shall be firmly fastened to the post. The following types of hammer arrangements are included in this practice: Originally approved in Charge the mixing container with the heated aggregate and dry mix thoroughly approximately 5 s with scoop or spoon. In preparation for heating to compaction temperature the material should be warmed and worked until a loose mixture condition is obtained.
Current edition approved June 15, You may delete a document from your Alert Profile at any time. Historical Version s – view previous versions of standard. These notes and footnotes excluding those in tables and figures shall not be considered as requirements of the standard. 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. Last previous edition approved in as D—04 DOI: Users of this practice are cautioned that compliance with Specification D alone does not completely ensure reliable results. 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.

Place a piece of nonabsorbent paper, cut to size, in the bottom of the mold before the mixture is qstm. Need more than one copy? ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard.
It is up to the owner or specifier to establish the x6926 required number of blows to be used for compaction of the specimen in relation to the field.
