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

Reporting of test results in units other than inch-pound units shall not be regarded as nonconformance with this test method. Consequently, more trials may be required d11883 these materials to establish a reliable CBR. For more information, contact: Soil testing Lab Services: After the density has been determined, the unit weight is calculated in SI or inch-pound units, or both.

The dry unit weight is usually given as a percentage of maximum dry unit weight determined by Test Methods D or D Link to Active This link will always route to the current Active version of the standard.

For applications where the effect of compaction aatm 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. It is scientifically undesirable to combine the use of two separate sets of inchpound units within a single standard.

Your Asgm Profile lists the documents that will be monitored. Reliable testing depends on many factors; Practice D provides a means of evaluating some of those factors. The dry unit weight is usually given as a percentage of maximum dry unit weight determined by Test Methods D or D The SI units given in parentheses are mathematical conversions, which are provided for information purposes only and are not considered 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.

Already Subscribed to this document. 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. Users of this standard are cautioned that compliance with Practice D does not in itself ensure reliable results. Active view current version of standard. Ashm 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 CBR value obtained in this test forms an integral part of several flexible pavement design methods.

Density is mass per unit volume whereas unit weight is force per unit volume. Historical Version s – view previous versions of standard. Therefore, the standard unit for mass in this standard is aztm kilogram kg or gram gor both.
