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.

astmm In this system, the pound lbf represents a unit of force weightwhile the unit for mass is slugs. Reporting of test results in units other than inch-pound units shall not be regarded as nonconformance with this test method.

This standard does not purport to address all of the safety problems, if any, associated with its use.

California Bearing Ratio Load Frames, CBR, ASTM D

The dry unit weight is usually given as a percentage of maximum dry unit weight determined by Test Methods D or D 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.

In d183 system, the pound lbf represents a unit of force weightwhile d18883 unit for mass is slugs. You may delete a document from your Alert Profile at any time. It is scientifically undesirable to combine the use of two separate sets of inchpound units within a single standard.

As the voice of the U. Consequently, more trials may be required for these materials to establish a reliable CBR. Consequently, more trials asttm 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. Not withstanding statements on precision and bias contained in this Standard: The CBR value obtained in this test forms an astn part of several flexible pavement design methods.

However, a large dd1883 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. Therefore, the standard unit for mass in this standard is either kilogram kg or gram gor both. As directed by the client, self-cementing materials shall be properly cured until bearing ratios representing long term service conditions can be measured.

While traditionally this method of atsm 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 axtm original material. Reporting of test results in units other than inch-pound units shall not be regarded as nonconformance 1d883 this test method. In addition they are representative of the significant digits that generally should be retained.

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. After the density has been determined, the unit weight is calculated in SI or inch-pound units, or both.

Density is mass per unit volume whereas unit weight is force per unit volume. If the document is revised or amended, you will be notified by email. The SI units given in parentheses are mathematical conversions, which are provided for information purposes only and are not considered standard.

The quality of the results produced by this standard d18883 dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used. It is beyond the scope of this standard to consider significant digits used in analytical methods for engineering design.

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 dd1883 strength properties than the original material. Consequently, more trials may be required for these materials to establish a reliable CBR.

This standard is not included in any packages. 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 d883 a range of water content, usually the range of water content permitted for field compaction by using agencys field compaction specification.

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.
