asttm Users of this standard are cautioned that compliance with Practice D does not in itself ensure reliable results. It is beyond the scope of this standard to consider significant digits used in analytical methods for engineering design.

The CBR value obtained in this test forms an integral part of several flexible pavement design methods.

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 is usually given as a percentage of maximum dry unit weight determined by Test Methods D or D It is scientifically undesirable to combine the use of two separate sets of d18883 units within a single 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. 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 xstm.

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.

Consequently, more trials may be required for these materials to establish a reliable CBR. The SI units given in parentheses are mathematical conversions, which are ast, for information purposes only and are not considered standard.

As directed by the client, self-cementing materials shall be properly cured until bearing ratios representing long term service conditions can be measured. Note 1The agency performing this test can be evaluated in accordance with Practice D As directed by the engineer, self cementing materials shall be properly cured until bearing ratios representing long term service conditions can be measured.

This implicitly combines two separate systems of units; that is, the absolute system and the gravitational system. Density is mass per unit volume whereas unit weight is force per unit volume.
