ASTM D4718/D4718M – 15

If a soil contains cobbles or gravel, or both, test options may be selected which result in particles retained on a specific sieve being discarded for example the 4.

The person or agency specifying this practice shall specify a minimum percentage of oversize particles below which the practice need not be applied. Standards Subsctiption may be the perfect solution. Users of this standard are cautioned that compliance with Practice Ashm does not in itself ensure reliable results.

Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. Nat all aspects of this practice may be applicable in all circumstances. Not all aspects of this practice may be applicable in all circumstances.

The alternative designation given in brackets is for information only and does not represent a different standard sieve size. Reliable results depend on many factors; Practice D provides a means aztm evaluating some of those factors. However, the correction may not be of practical significance for soils with only small percentages of oversize particles. Active view current version of standard.

In this system, the pound lbf represents a unit of force weight. The unit weight-water content relations determined by the tests reflect the characteristics of the actual material tested, and not the characteristics of the total asmt material from which the test specimen was obtained. The practice also is considered valid when the oversize fraction is that portion retained on some other sieve, but the limiting percentage of oversize particles for which the correction is valid may be lower.

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

This standard has been written using the gravitational system of units when dealing with the inch-pound system. This implicitly combines two separate systems of units; that is, the absolute system and the gravitational system. For some gradations, this interference 4d718 begin to occur at lower percentages of oversize particles, so the limiting percentage must be lower for these materials to avoid inaccuracies in the computed correction.

The practice atm is considered valid when the oversize fraction is that portion retained on some other sieve, but the limiting percentage of oversize particles for which the correction is valid may be lower.

It is scientifically undesirable to combine the use of two separate sets of inch-pound units within a single standard.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

However, the correction may not be of practical significance for soils with only small percentages of oversize particles. For some gradations, this interference may begin to occur at lower percentages of oversize particles, so the x4718 percentage must be lower for these materials to avoid inaccuracies in the computed correction.

This practice provides a mathematical equation for correcting the unit weight and water content of the finer fraction of a soil, tested to determine the unit weight and water content of the total soil.

The person or agency specifying this practice shall specify a minimum percentage of oversize particles below which the practice need not x4718 applied.

If a soil used in construction contains large particles, and only the finer fraction is used for laboratory tests, some method of correcting the laboratory test results to reflect the characteristics of d47718 total soil is needed.
