As directed by the client, self-cementing materials shall be properly cured until bearing ratios representing long term service conditions can be measured. Astm d1883, a large astm d1883 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.

Reliable testing depends on many factors; Practice Astm d1883 provides a means of evaluating some of those factors.

Consequently, astm d1883 trials may be required for these materials to establish a reliable CBR. The precision of this test method astm d1883 dependent on the competence of the personnel performing it and the suitability of the equipment and facilities used. This standard does not purport d18883 address all of the safety problems, if any, associated with its use.

California Bearing Ratio Load Frames, CBR, ASTM D

In astm d1883 system, the pound lbf represents a unit of force weightwhile the unit for mass is slugs. For applications where the effect of astm d1883 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 astm d1883 permitted for field compaction by using agencys field compaction specification.

Reliable results depend on many factors; Practice D provides a means of evaluating some astm d1883 those factors. Link to Astm d1883 This link will always d1838 to the current Active version of the standard. While adtm 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 atsm than the original material.

The SI units given in parentheses are mathematical conversions, which are provided for information purposes only and are not considered standard. 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 astm d1883.

In this system, the pound lbf represents a unit of force weightwhile the unit for mass is slugs. Therefore, the standard unit for mass in this standard is either kilogram kg or gram gor both.

The dry unit weight is usually given as a percentage of maximum dry unit weight determined by Test Methods D or D The criteria for test astm d1883 preparation of self cementing and other materials which gain strength astm d1883 time must be based on a geotechnical engineering evaluation.

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

The SI units given in parentheses are mathematical conversions, which are provided for information purposes only and are not considered standard. This implicitly combines two separate systems of units; that is, the absolute system and the gravitational system.

After the density has been determined, the unit weight is calculated in SI or inch-pound units, or both.

The CBR value obtained in this test forms an integral part of several flexible pavement design methods. For Individuals with astm d1883 special assistance for disabilities or limited English proficiency Please contact our Title VI specialist at 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. Consequently, more trials may be required for these materials to establish astm d1883 reliable CBR.

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.

It is beyond the scope of this standard to consider significant digits used in analytical methods for engineering design. 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.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of astm d1883 standard.

The dry unit weight specified is astm d1883 the minimum percent compaction allowed by the using agencys field compaction specification.

In addition they are representative of the significant digits that generally should be retained.

As directed by the engineer, self cementing materials shall be properly cured astm d1883 bearing ratios representing long term service conditions can be measured.
