The dry unit weight specified is normally the minimum percent compaction allowed d18883 the using agencys field compaction specification. This implicitly combines two separate astm d1883 of units; that is, the absolute system and the gravitational system.

For applications d1883 the effect of compaction water content on CBR is unknown or where it is desired to account for its effect, the CBR is determined for a range of water content, usually the range of water content permitted for field compaction by d1883 agencys field compaction specification. Reliable testing depends on many factors; Practice D provides a means of evaluating some of astm d1883 factors. Density is mass per unit astm d1883 whereas unit weight is force per unit volume.

For Individuals with needing special assistance for disabilities or limited English proficiency Please contact our Title VI specialist at The SI units given in parentheses are mathematical conversions, d183 are provided for information purposes only and are not considered standard.

Astm d1883 dry unit weight is usually given as a percentage of maximum dry unit weight determined by Test Ast D astm d1883 D The SI equivalents shown in parentheses may be approximate. Link to Active This link will always route to the current Active version of the standard. In this system, the pound lbf represents a unit of force weightwhile the unit for mass is slugs.

Note 1The agency performing this test can be evaluated in accordance astm d1883 Practice D After the density has been determined, the unit weight is calculated in SI or inch-pound units, or both. The quality of the results produced by this standard is dependent on the astm d1883 of the personnel performing it, and the suitability of the equipment and facilities used.

Consequently, more trials may be required for these materials to establish a reliable CBR. Users of this standard are cautioned that compliance with Practice D does not in itself ensure reliable results.

Consequently, more trials may be required for these materials astm d1883 establish a reliable CBR. As directed by the client, self-cementing astm d1883 shall be properly cured until bearing ratios representing long term service conditions can be measured.

In addition they are representative of the significant digits that generally should be retained. Consequently, more trials may be astm d1883 for these materials to establish a reliable CBR. However, a large experience database has been developed using this test method for materials for astm d1883 the gradation has been modified, and satisfactory design methods astm d1883 in use based on the results of tests using this procedure.

Therefore, the standard unit for mass in this standard is either kilogram kg or gram gor both. As directed by the engineer, self cementing materials shall be properly cured until astm d1883 ratios representing long term service conditions can be measured.

Reporting of test results in units other than inch-pound units shall not be regarded as nonconformance astm d1883 this test method. 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.

However, a large experience base has developed using this test method for materials for which the gradation has been modified, and satisfactory design methods are in astm d1883 based on the results of tests using this procedure.

The CBR value obtained in this test forms xstm integral part d188 several astm d1883 pavement design methods. While traditionally this method of astm d1883 preparation has been used to avoid the astm d1883 inherent in testing materials containing large particles in the CBR test asym, the modified material may have significantly different strength properties than the original material.
