Standard: ASTM D2940

Type I mixtures shall consist astm d 2940 stone, gravel, or slag with natural or crushed sand and fine mineral particles passing a No. This specification covers quality-controlled graded aggregates that, when hauled to and properly spread and compacted on a prepared grade to appropriate density standards, may be expected to provide adequate stability and load support for use as highway or airport bases or subbases.

ICS Number Code This abstract is a brief summary of the referenced standard. Different tests shall be conducted in order to determine the following properties of the aggregates: Link to Active This link will always route to the current Active version of the standard. The astm d 2940 tests shall be performed: The method suggested is to require astm d 2940 on a firm foundation of astm d 2940 short control 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.

Combining values from the two systems may result in non-conformance with the standard. Where available and suitable, addition of natural sand or finer mineral matter, or both, is not prohibited.
