Combining values from the two systems may result in non-conformance with the standard. Type I mixtures shall consist of stone, gravel, or slag with natural or crushed sand and fine mineral particles passing a No. This abstract is a brief summary of the referenced standard.

On the other hand, Type II mixtures shall consist astm d 2940 natural or crushed sand with fine mineral astm d 2940 passing a No. Combining values from the two systems may result in non-conformance with the standard. Referenced Documents purchase separately The documents listed astm d 2940 are referenced within the subject standard but are not provided as part of the standard.

The method suggested is to require compaction on a firm foundation of a 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.

These notes and footnotes excluding those astm d 2940 tables and figures shall not be considered as requirements of the standard. The engineer is cautioned to provide appropriate construction specifications to ensure compaction to an extent that further densification from traffic loadings on the completed pavement will be insignificant.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. This specification covers the quality and grading of the following materials for use in the construction of subbase, base, astm d 2940 surface courses: ICS Number Code Referenced Documents purchase separately The astm d 2940 listed below are referenced within the subject standard but are not provided as part of the standard.

The method suggested is to require compaction on a astm d 2940 foundation of a 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.

Fine aggregate passing through the sieve shall normally consist of fines from the operation of crushing the coarse aggregate. The requirements are intended to cover materials having normal specific gravity, absorption, and gradation characteristics.

Note 1—The engineer is cautioned to provide appropriate construction specifications to ensure compaction to an extent that further densification from traffic loadings on the completed pavement will be insignificant. The astm d 2940 stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Where available and suitable, addition of natural sand astm d 2940 finer mineral astm d 2940, or both, is not prohibited.

Where astm d 2940 materials are to be used, appropriate limits suitable to their use must be specified. The following tests shall be performed: Different tests shall be conducted in astm d 2940 to determine the following properties of the aggregates: Referenced Documents purchase separately The documents listed below are referenced within the subject standard but 29440 not provided as part of the standard.

Coarse aggregate retained on the sieve shall consist of durable particles of crushed astm d 2940, gravel, or slag capable of withstanding the effects of handling, spreading, and compacting without degradation productive of deleterious fines. This abstract is a brief summary of the referenced standard. This standard does not purport to address all of the safety concerns, if any, associated with its use.
