ASTM D6092-21

Standard Practice for Specifying Standard Sizes of Stone for Erosion Control

SIGNIFICANCE AND USE
5.1 The standard size designations listed in this practice are provided so that the design team, consumer, and the producer have a common reference in sizing stone materials used in erosion control. The design team should assign a materials survey, and rock quality testing series to determine which quarry sources may have suitable blasting and processing procedures to produce the required gradations. The design team should recognize the fact that not all sources are capable of or willing to produce the required gradations. Only those sources listed by the design team should be considered for construction of the project.  
5.2 The standard size designations provided in this guide are suitable for protective surfacing and structures designed for erosion control. These sizes are for typical structures such as jetties, revetments, groin baffles, bulkheads, lining for drainage/irrigation ditches and for intake or outlet facilities, bridges and stream channel banks, gabions, and slope protection for earth embankment and rock-fill dams.  
5.3 The design selection of stone sizes, durability, placement, filter/bedding materials, or geotextiles, steepness of slopes for placement, and layer thickness are beyond the scope of this guide.
SCOPE
1.1 This practice covers size designations and maximum ranges in mass or gradation for standard sizes for riprap, spalls, or bedding, or both, used for slope protection of dam embankments, streambank erosion control, bridge piers and abutments. Sizes used for outer harbor structures such as breakwalls, revetments, confined diked disposal structures (heretofore described as armor stone, cover stone, or dimension stone) for which stone sizes range between 5 and 25 tons, or that require cut dimensions for layed-up structures are beyond the scope of this practice.  
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are rationalized conversions to SI units that are provided for information only and are not considered standard.  
1.3 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This practice offers an organized collection of information or a series of options and does not recommend a specific course of action. This document cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this practice may be applicable in all circumstances. This ASTM standard is not intended to represent or replace the standard of care by which the adequacy of a given professional service must be judged, nor should this document be applied without consideration of a project's many unique aspects. The word “Standard” in the title of this document means only that the document has been approved through the ASTM consensus process.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
