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 astn of tests using this procedure.

The dry unit weight is usually given as a percentage of maximum dry unit weight determined by Test Methods D or D It is beyond the scope of this standard to consider significant digits used in analytical methods for engineering design.

The dry unit weight is usually given as a ast of maximum dry unit weight determined by Test Methods D or D 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 asrm a specified compaction effort.

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

In this standard, density is given only in SI units. Active view current version of standard. Not withstanding statements on precision and bias contained in this Standard: 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 D or D Need more than one copy? 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 the using agencys field compaction specification. This implicitly combines two separate systems of units; that is, the absolute system and the gravitational system.

Reliable testing depends 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.

Reporting aatm test results in units other than inch-pound units shall not be regarded as nonconformance with this test method. In addition they are representative of the significant digits that generally should be retained.

Consequently, more trials may be required for these materials to establish a reliable CBR. Density is mass per unit volume whereas unit weight is force per unit volume. While traditionally this method of specimen preparation has been used to avoid the error inherent s1883 testing dd1883 containing large particles in the CBR test apparatus, the modified material may have significantly different strength properties than the original material.

Consequently, more trials may be required for these materials to establish a reliable CBR. Subscription pricing is determined by: 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.
