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.

Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors. The SI units given in parentheses are mathematical conversions, which are provided for information purposes only and are not considered standard.

Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Users of this method are cautioned that compliance with Practice Aetm does not in itself assure reliable testing.

This standard is also available to be included in Standards Subscriptions. Your Alert Profile lists the documents that will be monitored. In addition they are representative of the significant digits that generally should be retained. Reporting of test results in units other than inch-pound units shall not be regarded as nonconformance with aetm test method.

However, a large experience database has been developed using this test method for atm 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 specified is normally the minimum percent compaction allowed by the using agencys field compaction specification. Soil testing Back to Results Print. Not withstanding statements on precision and bias contained in this Standard: Active view current version of standard. It is beyond the scope of this standard to consider significant digits used in analytical methods for engineering design.

Note 1The agency performing this test can be evaluated in accordance with Practice D In this system, the pound lbf represents a unit of force weightwhile the unit for mass is slugs. The dry unit weight is usually given as a percentage of maximum dry unit weight determined by Test Methods Adtm or D The dry unit weight is usually given as a percentage of maximum dry unit weight determined by Test Methods D or D Link d11883 Active This link will always route to the current Active version of the standard.

The dry unit weight is usually given as f1883 percentage of maximum dry unit weight determined by Test Methods D or D After the density has been determined, the unit weight is calculated in SI or inch-pound units, or both.

Consequently, more trials may be required for these materials to establish a reliable CBR.

The CBR value obtained in this test forms an integral part of several flexible pavement design methods. As directed by the engineer, self cementing materials shall be properly cured until bearing ratios representing long term service conditions can be measured. In addition they are representative of the significant digits that generally should be retained.

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 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. Consequently, more trials may be required for these materials to establish a reliable CBR.

The SI asmt shown in parentheses may be approximate. 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.

While traditionally this method of specimen preparation has been d18833 to avoid the error inherent in testing materials containing large particles in the CBR test apparatus, the modified material may have significantly different d183 properties than the original material. For 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.
