The method astm d 2940 is to require compaction on a firm foundation of a short astm d 2940 strip of the material at a suitable moisture content, by means of vibratory or other proven effective rollers or tampers, until no further increase in density results.

Coarse aggregate retained on the sieve shall consist astm d 2940 durable particles of crushed stone, gravel, or slag capable of withstanding the effects astm d 2940 handling, spreading, and 2904 without degradation productive of deleterious fines.

Combining values from the two systems may result in non-conformance with the standard. Historical Version s – view previous versions of standard.

Wstm tests shall be conducted in order to determine the following properties of the aggregates: This specification covers quality-controlled graded aggregates that, when hauled to and properly spread and compacted on a astm d 2940 grade to appropriate astm d 2940 standards, may be expected to provide adequate stability and load astm d 2940 for use as highway or airport bases or subbases.

These notes and footnotes excluding those in tables and figures shall not be considered as requirements of the standard. This specification covers the quality and grading of the following materials for use in the construction of subbase, base, and surface courses: ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

Type I mixtures shall consist of stone, gravel, or slag with natural or crushed sand and fine mineral particles passing a No.

Where other materials are to be used, appropriate limits suitable to their use must be specified. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not astm d 2940 as part of the standard. Fine aggregate passing through the sieve shall normally consist of fines from the operation of crushing the coarse aggregate. Where available and suitable, addition of astm d 2940 sand or finer mineral matter, or both, is not prohibited.

Note 1—The engineer is cautioned to provide appropriate construction specifications to adtm compaction to an extent that further densification from traffic loadings on the completed pavement will be insignificant.
