Standard Test Method for Determination of Rolled Erosion Control Product (RECP) Performance in Protecting Hillslopes from Rainfall-Induced Erosion
 N D6459

Annotation

This test method covers the guidelines, requirements and procedures for evaluating the ability of Rolled Erosion Control Products (RECPs) to protect hillslopes from rainfallinduced erosion. Critical elements of this protection are the ability of the RECP to:

Absorb the impact force of raindrops, thereby reducing soil particle loosening through "splash" mechanisms;

Slow runoff and encourage infiltration, thereby reducing soil particle displacement and transport through "overland flow" mechanisms;

Absorb shear forces of overland flow; and,

Trap soil particles beneath.

This test method utilizes full-scale testing procedures, rather than reduced-scale (bench-scale) simulation, and is patterned after conditions typically found on construction sites at the conclusion of earthwork operations, but prior to the start of revegetation work. Therefore this considers only unvegetated conditions.

This test method provides a comparative evaluation of an RECP-to baseline bare soil conditions under controlled and documented conditions.

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.

All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026, unless superseded by this standard.
