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.

The dry unit weight is usually given as a percentage of maximum dry unit weight determined by Test Methods D or D Astk is mass per unit volume whereas unit weight is force per unit volume.

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

ASTM D1883

This implicitly combines two separate systems of units; that is, the absolute system and the gravitational system. This standard does not purport to address all of the safety problems, if any, f1883 with its use. 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.

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 has been modified, and satisfactory design methods are in use based on the results of tests using this procedure. Your Alert Profile lists the documents that will be monitored.

It is beyond the scope of this standard to consider significant digits used in analytical methods for engineering design. 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.

Consequently, more trials may be required for these materials to establish a reliable CBR. Users of this method are cautioned that compliance with Practice D does not in itself assure reliable testing.

It is scientifically undesirable to combine the use of two separate sets of inchpound units xstm a single standard. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Subscription pricing is determined by: It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory asgm prior to use.

This standard is not included in any packages. Note 1The agency performing this test can be evaluated in accordance with Practice D The SI units given in parentheses are mathematical conversions, which are provided for information purposes only and are not considered standard. Consequently, more trials may be required for these materials to establish a reliable CBR. This asstm combines two separate systems of units; that is, the absolute system and the gravitational system.

In this standard, density is given only in SI units. Therefore, the standard unit for mass in this standard is either kilogram kg or gram gor both. Not withstanding statements on precision and bias contained in this Standard: Active view current version of aetm. The criteria for test specimen preparation of self cementing and other materials which gain strength with time must be based on a geotechnical engineering evaluation.

Density is mass per unit volume whereas unit weight is force per unit volume. The dry unit weight is usually given as a percentage of maximum dry unit weight determined by Test Methods D or D The SI equivalents shown in parentheses may be approximate.

Soil testing Lab Services: The CBR value obtained in this test forms an integral part of several flexible pavement design methods. Agencies which meet the criteria of Practice D are generally considered capable of asfm and objective testing. Historical Version s – view previous versions of standard.

In addition they are representative of the significant digits that generally should be retained. This standard is also available to be included in Standards Subscriptions. In this standard, density is given only in SI units. The precision of this test method is dependent on the competence of the personnel performing it and the suitability of the equipment and facilities used.

After the density has been determined, ashm unit weight is calculated in SI or inch-pound units, or both. California bearing ratio, pavement subgrade, subgrade, pavement subbase, subbase, pavement base course, base course, pavement design, flexible pavements, bearing ratio, CBR.

As directed by the client, self-cementing materials shall be properly cured until bearing ratios representing long term service conditions can be measured. Therefore, the standard unit for mass in this standard is either kilogram kg or gram gor both.

This test method is used to evaluate the potential strength of subgrade, subbase, and base course material, including recycled materials for use in road and airfield pavements. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. Request Quote Client Login. After the density has been determined, the unit weight is calculated in SI or inch-pound units, or both.
