ASTM D6459-11

This document is not anASTM standard and is intended only to provide the user of anASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation:D6459–07 Designation: D6459 – 11
Standard Test Method for
Determination of Rolled Erosion Control Product (RECP)
Performance in Protecting Hillslopes from Rainfall-Induced
1
Erosion
This standard is issued under the fixed designation D6459; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope*
1.1 This test method covers the guidelines, requirements and procedures for evaluating the ability of Rolled Erosion Control
Products (RECPs) to protect hillslopes from rainfall-induced erosion. Critical elements of this protection are the ability of the
RECP to:
1.1.1 Absorb the impact force of raindrops, thereby reducing soil particle loosening through “splash” mechanisms;
1.1.2 Slow runoff and encourage infiltration, thereby reducing soil particle displacement and transport through “overland flow”
mechanisms;
1.1.3 Absorb shear forces of overland flow; and,
1.1.4 Trap soil particles beneath.
1.2 This test method utilizes full-scale testing procedures, rather than reduced-scale (bench-scale) simulation, and is patterned
afterconditionstypicallyfoundonconstructionsitesattheconclusionofearthworkoperations,butpriortothestartofrevegetation
work. Therefore this considers only unvegetated conditions.
1.3 This test method provides a comparative evaluation of an RECP-to baseline bare soil conditions under controlled and
documented conditions.
1.4The1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical
conversions to inch-pound units, which are provided for information only and are not considered standard.
1.5All1.5 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in
Practice D6026, unless superseded by this standard.
1.5.1 The procedures used to specify how data are collected/recorded or calculated, in this standard are regarded as the industry
standard. In addition, they are representative of the significant digits that generally should be retained.The procedures used do not
consider material variation, purpose for obtaining the data, special purpose studies, or any considerations for the user’s objectives;
and it is common practice to increase or reduce significant digits of reported data to be commensurate with these considerations.
It is beyond the scope of this standard to consider significant digits used in analytical methods for engineering design.
1.6 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. Also, the user must comply with prevalent regulatory codes, such as OSHA (Occupational Health and
Safety Administration) guidelines, while using the test method.
