In this system, the pound lbf represents a unit of force weightwhile the unit for mass is slugs. Request Quote Client Login.

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.

Already Subscribed to this document. This standard is also available to be included in Standards Subscriptions. Consequently, more trials may be required for these materials to establish a reliable CBR. The dry unit weight is usually given as a percentage of maximum dry unit weight determined by Test Methods D or D This implicitly combines two separate systems of units; that is, the absolute system and the gravitational system.

Users of this e1883 are cautioned atsm compliance with Practice D does not in itself ensure reliable results. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

The CBR value obtained in this test forms an integral part of several flexible pavement design methods. 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.

Therefore, the standard unit for mass in this standard is either kilogram kg or gram gor both. As directed by the client, self-cementing materials shall be properly cured until bearing ratios representing long term service conditions can be measured. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

The dry unit weight is usually given as a percentage of maximum dry unit weight determined by Test Methods D or D As directed by the engineer, self cementing materials shall be properly cured until bearing ratios representing long term service conditions can be measured.

Density is mass per unit volume whereas unit weight is force per unit d1883. 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.

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

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.

The dry unit weight is usually given as a percentage of maximum dry unit weight determined by Test Methods D or D Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

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.
