ASTM D Standard

Consequently, more trials may be required for these materials to establish a reliable CBR. It is scientifically undesirable to combine the use of two separate sets of inchpound units within a single standard.

Consequently, more trials may be required for these materials to establish a reliable CBR. As directed by the engineer, self cementing materials shall be properly cured until bearing ratios representing long term service conditions can be measured.

We have no amendments or corrections for this standard. The dry unit weight is usually given as a percentage of maximum dry unit d18833 determined by Test Methods D or D Reliable testing depends on many factors; Practice D provides a means of evaluating some of those factors. It is beyond the scope of this standard to consider significant digits used in analytical methods for engineering design. After the density has been determined, the unit weight is calculated in SI or inch-pound units, or both.

In addition they are representative of the significant digits that generally should be retained. As directed by the client, self-cementing materials shall be properly cured until bearing ratios representing long term service conditions can be measured.

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. The SI astn given in parentheses are mathematical conversions, which are provided for information purposes only and are not considered standard.

It is beyond the scope of this standard to consider significant digits used in analytical methods for engineering design. Density is mass per unit volume asmt unit weight is force per unit volume. Not withstanding statements on precision and bias contained in this Standard: The dry unit weight specified is normally the minimum percent compaction allowed by the using agencys field compaction specification.

As the voice of the U. 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.

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. Request Quote Client Login.

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.

This standard is not included in any packages. Ashm standard does not purport to address all of the safety problems, if any, associated with its use. The SI units given in parentheses are mathematical conversions, which are provided for information purposes only and are not considered standard. It is scientifically undesirable to combine the use of two separate sets of inchpound units within a single standard.
