Soil testing Lab Services: Note 1The agency performing this test can be evaluated in accordance with Practice D Reliable testing depends on many factors; Practice D provides a means of evaluating some of those factors.

This standard is not included in any packages. 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.

ASTM D Standard

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.

Not withstanding statements on precision and bias contained in this Standard: It is scientifically undesirable to combine the use of two separate sets of inchpound units within a single standard. The dry unit weight is usually given as a percentage of maximum dry unit weight determined by Test Methods D or D Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors. 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. For more information, contact: Historical Version s – view previous versions of standard. Users of this standard are cautioned that compliance with Practice D does not in itself ensure reliable results. The dry unit weight specified is normally the minimum percent compaction allowed by the using agencys field compaction specification.

As directed by the client, self-cementing materials shall be properly cured until bearing ratios representing long term service conditions can be measured. You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server.

ASTM D1883

For applications where the effect of compaction water content on CBR is unknown or where it is desired to account for its effect, the CBR is determined for a range of water ashm, usually the range of water content permitted for field compaction by using agencys field compaction s1883. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

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. Density is mass per unit volume whereas unit weight is force per asfm volume.

As the voice of the U. 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.

In this standard, density is given only in SI units. Need more than one copy? The dry unit weight is usually given as a percentage of maximum dry unit weight determined by Test Methods D or D Standards Subsctiption may be the perfect solution.

Therefore, the standard unit for mass in this standard is either kilogram kg or gram gor both. 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.

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. Consequently, e1883 trials may be required for asm materials to establish atm reliable CBR.

After the density has been determined, the unit weight is calculated in SI or inch-pound units, or both. Reporting of test results in units other than inch-pound units shall not be regarded as nonconformance with this test method. The quality asgm 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.

Agencies which meet the criteria of Practice D are generally considered capable of competent and objective testing. If the document is revised or amended, you will be notified by email.

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.

Active view current version of standard. 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. The precision of this test method is dependent on the competence of the personnel performing it and asrm suitability of wstm equipment and facilities used. 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.

Density is mass per unit volume whereas unit weight is force per unit volume. Users of this method are cautioned that compliance with Practice D does not in itself assure reliable testing. While traditionally this method of specimen preparation has been used to avoid the error inherent in testing materials containing large particles in the CBR sstm apparatus, the modified material may have significantly different strength properties than the original material.

In this system, the pound lbf represents a unit of force weightwhile the unit for mass is slugs. This implicitly combines two separate systems of units; that wstm, the absolute system and the gravitational system.
