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. This implicitly combines two separate systems of units; that is, the absolute system and the gravitational system.

Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. It is the r1883 of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory f1883 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 Your Alert Profile lists the documents that will be monitored. However, a large experience base has developed using this dd1883 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.

In this system, the pound lbf represents a unit of force weightwhile the unit for mass is slugs. Link to Active This link will always route to the current Active version of the standard. In addition they are representative of the significant digits that generally should be retained. Please first verify your email before subscribing to alerts. Soil testing Lab Services: 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.

Reliable testing depends on many factors; Practice D provides a means of evaluating some of those factors. It is beyond the scope of this standard to consider significant digits used in analytical methods for engineering design.

Density is mass per unit volume whereas unit weight is force per unit volume. Referenced Documents purchase separately The documents listed 1d883 are referenced within the subject standard but are not provided as part of the standard.

This implicitly combines two separate systems of units; that is, the absolute system and the gravitational system. 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 aastm water content permitted for field compaction by using agencys field compaction specification.

However, a large experience database has been developed using this test method for materials for which d18883 gradation has been modified, and satisfactory design methods are in use based on the results of tests using this procedure. Subscription pricing is determined by: In this system, the pound lbf represents a unit of force weightwhile the unit for mass is slugs. 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.

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

The precision of this test method is dependent on the competence of the personnel performing it and the d11883 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 As directed by the client, self-cementing materials shall be properly cured until bearing ratios representing long term service conditions can be measured.

Not withstanding statements on precision and bias contained in this Standard: As the voice of the U. In this standard, density is given only in SI units.

Awtm applications where the effect of compaction water content of CBR is small, such adtm 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.
