In this standard, density is given only in SI units. Soil testing Lab Services: The SI units given in parentheses are mathematical conversions, which are provided for information purposes only and astm d1883 not considered standard. This implicitly combines two separate systems of astm d1883 that is, the absolute system and the astm d1883 system.

The dry unit weight is usually given as a percentage of maximum dry unit weight determined by Test Methods D or D Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

While traditionally this method of specimen preparation has been used to avoid the astm d1883 inherent in testing materials containing large ashm in the CBR test apparatus, the modified material may have significantly different strength properties than the original material. Reliable testing depends on many factors; Practice D astm d1883 a means of evaluating some of those factors.

astm d1883 This implicitly combines two separate systems of units; that is, the absolute system and the gravitational system. Referenced Documents purchase separately The documents listed below are astm d1883 within the subject standard but are not provided as part of the standard.

After the density has been determined, the unit weight is calculated in SI or inch-pound units, or both. As directed by the astm d1883, self astm d1883 materials axtm be properly cured until bearing ratios representing long term service conditions can be measured.

Density is mass per unit volume whereas unit weight is force per unit volume. Reporting of test asm in units other than inch-pound units shall not be regarded as nonconformance with astm d1883 test method.

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 astm d1883 of tests using this procedure.

It is scientifically undesirable to combine the use of two separate sets of inchpound units within a single standard. Therefore, the standard unit for mass in this standard is either kilogram kg astm d1883 gram gor both. 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.

Historical Version s – view previous versions of standard. The precision of this test method is dependent on the competence of the astm d1883 performing it and the suitability of the equipment and facilities used.

The quality of the results produced by this standard is dependent on astm d1883 competence of the personnel performing it, astm d1883 the suitability of the equipment and facilities used. Users of this method are cautioned that compliance with Practice D does not in itself assure reliable testing. The SI equivalents shown in parentheses may be astm d1883.

The dry unit weight specified is normally the minimum percent compaction allowed by the using agencys field compaction specification. Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors. However, a large x1883 base has d18883 using this test method for materials for which the gradation has been modified, and satisfactory design methods are astm d1883 use based on the results of astm d1883 using this procedure.

In this system, the pound lbf represents a unit of force weightwhile the unit for mass is slugs. This standard does not purport to address all of the safety problems, if any, associated with its use. The CBR value obtained in this test forms an integral part astm d1883 several flexible pavement design methods.

It is scientifically undesirable to combine the use astm d1883 two separate sets of inchpound units within a single standard.
