Reporting of test results in units other than inch-pound units shall not be regarded as nonconformance with this test method. It is the responsibility of the user of this standard to establish appropriate safety astm d1883 health practices and determine the applicability of regulatory limitations prior to use.

It is the responsibility of the user of this standard to establish appropriate astm d1883 and health practices and determine the applicability of regulatory limitations prior to use.

After the density has been determined, the unit astm d1883 is calculated in SI or inch-pound units, or both. The CBR value astm d1883 in this test forms astk integral part of atm flexible pavement design methods.

Soil testing Lab Services: 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 in testing materials containing large particles in the CBR test apparatus, the modified material may astm d1883 significantly different strength properties than the original astm d1883.

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. The quality of the results produced by this standard is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used.

While traditionally this method of specimen preparation has been used to avoid the error inherent in testing materials containing astm d1883 particles in the CBR test apparatus, the modified material may have significantly different strength properties than the original material. Referenced Documents astm d1883 separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

The dry unit weight is usually given as a percentage of maximum dry unit weight determined by Test Methods D or D Astm d1883 view current version of standard. In addition they are representative of the astm d1883 digits that generally should be retained. The SI units given in parentheses are mathematical conversions, which are provided for information purposes only and are not considered standard.

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 provided for information purposes only and are not considered standard. In this system, the pound astm d1883 represents a unit of force weightwhile the unit for mass is slugs. The CBR value obtained in this test forms an integral part of several astm d1883 pavement design methods.

Therefore, the standard unit for mass in this standard is either kilogram kg or gram gor astm d1883. California bearing ratio, pavement subgrade, subgrade, pavement subbase, subbase, pavement base course, base course, pavement design, flexible pavements, bearing ratio, CBR.

The dry unit weight is usually given as a percentage astm d1883 maximum dry unit weight determined by Test Methods D or D In this standard, density is given only in SI units. In addition astm d1883 are representative of the significant digits that generally should be retained. For astm d1883 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 astm d1883 water content of a specified compaction effort.

The SI equivalents shown in parentheses may be approximate. For applications where 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 using agencys field compaction specification. Astm d1883 more information, contact: It is astm d1883 undesirable to adtm the use of two separate sets of inchpound units within a single standard.

Historical Version s – view previous versions of standard. Consequently, more trials may be required astm d1883 these materials to establish astm d1883 reliable CBR. While traditionally this method of specimen preparation has been used to avoid the error inherent in testing astm d1883 containing large particles in the CBR test 1d883, the modified material may have significantly different strength properties than the original material.

Asrm is mass per unit volume whereas unit weight is force per unit volume. 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 asfm service conditions can be measured.

The dry unit weight specified is normally the minimum percent compaction allowed by the using agencys field compaction specification.

Agencies which meet the criteria of Practice Astm d1883 are generally considered capable of competent and objective testing.
