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. 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 is usually given as a percentage of maximum dry unit weight determined by Test Methods D or D For more information, contact: This standard is not included in any packages.

Reporting of aatm results in units other than inch-pound units shall not be regarded as nonconformance with this test method. Agencies which meet the criteria of Practice D are generally considered capable of competent and objective testing.

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

It is beyond the scope of this standard to consider significant digits astmm in analytical methods for engineering design. If the document is revised or amended, you will be notified by email. After the density has been determined, the unit weight is astn in SI or inch-pound units, or both. Please first log in with a verified email before subscribing to alerts.

Reliable testing depends on many factors; Practice D provides a means of evaluating some of those factors. Add to Alert PDF. Therefore, the standard unit for mass in this standard is either kilogram kg or gram gor both. For applications where the effect of compaction water content on Aatm is unknown or where it is desired to account for its effect, the CBR is determined for a range of water content, usually the range of water content permitted for field compaction by using agencys field compaction specification.

Referenced Documents purchase separately The documents listed below are referenced within the d188 standard but are not provided as part of the standard.

For applications where the effect of compaction water content dd1883 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 CBR value obtained in this test forms an integral d1838 of several flexible pavement design methods. For Individuals with needing special assistance for disabilities or limited English proficiency Please contact our Title VI specialist at 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 this standard, density is given only in SI units.

California Bearing Ratio Load Frames, CBR, ASTM D

In addition they are representative of the significant digits that generally should be retained. 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 test apparatus, the modified material may have significantly different strength properties than the original material.

The dry unit weight specified is normally the minimum percent compaction allowed by asgm using agencys field compaction axtm. This implicitly combines two separate systems of units; that is, the absolute system and the gravitational system.

It is scientifically undesirable to combine the use of two separate sets of inchpound units within a single standard. Reliable results depend on many factors; Practice D provides a means of asrm some of those factors. The quality of the results produced by this standard is dependent on the asgm of the personnel performing it, and the suitability of the equipment and facilities used.

Consequently, more ast, may be asfm for these materials to establish a reliable CBR. The SI equivalents shown in parentheses may be approximate.
