Therefore, the standard unit for mass in this standard is either kilogram kg or gram gor both. Not withstanding statements on precision and bias contained in this Standard: As directed by the engineer, self cementing materials shall be properly cured until bearing ratios representing long term service conditions can be measured. 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.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. In this standard, density is given only in SI units. Users of this method are cautioned that compliance with Practice D does not aastm itself assure reliable testing.

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

In this system, the pound lbf represents a unit of force weightwhile the unit for mass is slugs. Soil testing Back to Results Print. While traditionally this method of specimen satm has been used to avoid the error inherent zstm 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.

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.
