ASTM-D5519:2007 Edition

1.1 These test methods cover the particle size and mass analysis of natural and man-made riprap and related materials, including filter stone or coarse bedding materials.

1.2 These test methods are generally intended for riprap and related materials. They are applicable for mixtures of stones screened from natural deposits, blast rock, processed materials from quarried rock, or recycled concrete. They are applicable for sizes 3 in. (75 mm) and above, with the upper size limited only by equipment available for handling and weighing the individual particles.

1.3 Four alternate procedures are provided. There is a wide range in the level of effort and the precision of the test procedures. It is important for specifiers to indicate the test procedure. Test reports should clearly indicate which procedure was used.

Note 1

While conducting these test methods, it may be convenient to collect data on other attributes, such as the amount of slab pieces and deleterious materials.

1.4 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D 6026

1.5 The values stated in inch-pound units are to be regarded as the standard. The metric equivalents of inch-pound units given in parentheses may be approximate.

This standard does not purport to address all of the safety concerns, if any, associated with its use. 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. Specific precautionary statements are given in Section 7.
