Combining values from the two systems may result in non-conformance with the standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. 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.

It is the responsibility of the user of this standard to establish 2904 safety and health practices and determine the applicability of regulatory limitations prior to use.

Combining values from the two systems may result in non-conformance with the standard. The engineer is cautioned to provide appropriate construction specifications to ensure compaction to an extent that aatm densification from traffic loadings on the completed pavement will be insignificant.

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.
