As directed by the engineer, self cementing materials shall be properly cured until bearing ratios representing long term service conditions can be measured.
The SI units given in parentheses are mathematical conversions, which are provided for information purposes only and are not considered standard. In this system, the pound lbf represents a unit of force weightwhile the unit for mass is slugs. Already Subscribed to this document. However, a large experience database has been developed using this test method for materials for which the gradation has been modified, and satisfactory design methods are in use based on the results of tests using this procedure.
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.

asfm Users of this standard are cautioned that compliance with Practice D does not in v1883 ensure reliable results. The quality of the results produced by this standard is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used. While traditionally this method of specimen preparation has been used to avoid the error inherent in testing materials containing large particles in the CBR test apparatus, the modified material may have significantly different strength properties than the original material.
Link to Active This link will always route to the current Active version of the standard.
Density is mass per unit volume whereas unit weight is force per unit volume. This implicitly combines two separate systems of units; that is, the absolute system wstm the gravitational system. Users of this method are cautioned that compliance with Practice D does not in itself assure reliable testing. Proceed to Checkout Continue Shopping. The dry unit weight is usually given as a percentage of maximum dry unit weight determined by Test Methods D or D Please first verify your email before subscribing to alerts.
Therefore, the standard unit for mass in this standard is either kilogram kg or gram gor both.

It is scientifically undesirable to combine the use of two separate sets of inchpound units within a single standard. In this standard, density is given only in SI units.

ASTM D1883
The dry unit weight specified is normally the minimum percent compaction allowed by the using agencys field compaction specification. Density is mass per unit volume whereas unit weight is force per unit volume. Agencies which meet the criteria of Practice D are generally considered capable of competent and objective testing.
The dry unit weight is usually given as a percentage of maximum dry unit weight determined by Test Methods D or D We have no amendments or corrections for this standard. Request Quote Client Login. It is scientifically undesirable to combine the use of two separate sets of inchpound units within a single asmt. It is beyond the scope of this standard to consider significant digits used in analytical methods for engineering design.
