This standard does not purport to address all of the safety problems, if any, associated with its use. 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. The dry unit weight specified is normally the minimum percent compaction allowed by the using agencys field compaction specification. 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.

Reliable results depend on many factors; Practice D atm a means of evaluating some of those factors. 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.

It is scientifically undesirable to combine the use of two separate sets of inchpound units within a single standard. However, a large experience base has 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.

Reporting of test results in units other than inch-pound units shall not be regarded as nonconformance with this test method. 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.

It is beyond the scope of this standard to consider significant digits used in analytical methods for engineering design. Reporting of test results in units other than inch-pound units shall not be regarded as nonconformance with this test method.

The SI units given in parentheses are mathematical conversions, which are provided for information purposes only and are not considered standard. Active view current version of standard. For Individuals with needing special assistance for disabilities or limited English proficiency Please contact our Title VI specialist at Density is mass per unit volume whereas unit weight is force per unit volume.

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 asmt or gram gor both. In this system, the pound lbf represents a unit of force weight ast, while the unit for mass is slugs.

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.

Consequently, more trials may be required for these materials to establish a reliable CBR. However, a large experience database has been developed using this test method for materials for which the gradation d11883 been modified, and satisfactory design methods are in use based on the results of tests using this procedure.

Agencies which meet the criteria of Practice D are generally considered capable of competent and objective testing.

ASTM D Standard

This implicitly combines two separate systems of units; that is, the absolute system and the gravitational system. As directed by the engineer, self cementing materials shall be properly cured until bearing ratios representing long term axtm conditions can be measured. Add to Alert PDF. In addition they are representative of the significant digits that generally should be retained. Reliable testing depends on many factors; Practice D provides a means of evaluating some of those factors.

If the document is revised or amended, you will be notified by email. The CBR value obtained in this test forms an integral part of several flexible pavement design methods. Zstm applications where the effect of compaction water content of CBR is small, such a cohesionless, coarse-grained materials, or where an allowance is made for the effect of differing compaction water contents in the design procedure, the CBR may be determined at the optimum water content of a specified compaction effort.

The SI equivalents shown in parentheses may be approximate. In this standard, density is given only in SI units.

Users of this method are cautioned that compliance with Practice D does not in itself assure reliable testing. The dry unit weight is usually given as a percentage of maximum dry unit weight determined by Test Methods D or D Therefore, the standard unit for mass in this standard is either kilogram kg or gram gor both.

The dry unit weight is usually given as a percentage of maximum dry unit weight determined by Test Methods D or D In this system, the pound lbf represents a unit of force weightwhile the unit for mass is slugs.
