ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. Specimens should be accepted or rejected for further testing based on requirements of the criteria being applied.
Hand mix to ensure uniformity and quarter into appropriate sample size to conform to specimen height requirements. 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. After compaction, remove the collar and base plate.
The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. Multiple hammer operation will affect specimen density and is not recommended.
Your Alert Profile lists the documents that will be monitored. This practice is intended for use with laboratory asm plant produced bituminous mixtures with aggregate up to 25 mm 1 in.
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. Significance and Use 3. Thank you for interesting in our services.
In preparation for heating to compaction temperature the material should be warmed and worked until a loose mixture condition is obtained. The user should contact the manufacturer to establish appropriate mixing and compaction temperature ranges. 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.
The holders shall hold the compaction mold, collar, and base plate securely in position during compaction of the specimen. Apply the same number of compaction blows to the face of the reversed specimen.

Armored-glass or dial-type thermometers with metal stems are recommended. Suitable shields, baffle plates, or sand baths shall be used on the surfaces of the hot plates to minimize localized overheating. This standard is not included in any ast. Form a crater in the dry blended aggregate and weigh the required amount of bituminous material at mixing temperature into the mixture.
Place aggregate batches in containers on a hot plate or in an oven and heat to a temperature above but not exceeding the mixing temperature established in 5.
Size px x x x x D — 10 hammer by hand, as nearly perpendicular as possible to the base of the mold assembly during compaction. The following types of hammer arrangements are included in this practice: Please fill this form, we will try to respond as soon as possible.
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 compaction temperature for a cutback asphalt mixture is selected using a compositional chart of viscosity versus x6926 solvent for that cutback asphalt. A metal pan or bowl of sufficient capacity for hand mixing may also be used. Density and voids analysis are also conducted on specimens for mixture design and evaluation of field compaction.

The following types of hammer arrangements are included in this practice: Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every five years and if not revised, either reapproved or withdrawn.
There may or may not be a constant surcharge on top of the hammer handle. NOTE 7—Hammer shaft should be clean and lightly oiled. Remove the base plate and collar and reverse and reassemble the mold. Mechanical asym are available that operate at 1 asym 55 blows per minute and 2 equal to or greater than 75 blows per adtm. Best comparative results will be obtained by compacting all specimens with the same hammer and with no other hammers operating.
Allow the specimen to cool sufficiently to prevent damage and extract the specimen from the mold. Charge the mixing container with the heated aggregate and dry mix thoroughly approximately 5 s with scoop or spoon. We are a non-profit group that run this website to share documents.
