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.

The following tests shall be performed: Add to Alert PDF.

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. Fine aggregate passing through the sieve shall normally consist of fines from the operation of crushing the coarse aggregate.

Coarse aggregate retained on the sieve shall consist of durable particles of crushed stone, gravel, or slag capable of withstanding the effects of handling, spreading, and compacting without degradation productive of deleterious fines. Combining values from the two systems may result in non-conformance with the standard. This abstract is a brief summary of the referenced standard.
