Significance and Use | ||||||||||||||||||||||||||
This test method evaluates RECPs and their means of installation to: Reduce soil loss and sediment concentrations in stormwater runoff under conditions of varying channel conditions and soil type; Function within a composite system acting as vegetative reinforcement; and Improve water quality exiting the area disturbed by earthwork activity by minimizing mobilization of in-situ particles within the streambed. This test method models and examines conditions typically found on construction sites involving earthwork activities, including: highways and roads; airports; residential, commercial and industrial developments; pipelines, mines, and landfills; golf courses; etc. This test method is a performance test, but can be used for quality control to determine product conformance to project specifications. Caution is advised since information regarding laboratory specific precision is incomplete. For project specific conformance, unique project-specific conditions should be taken into consideration. |

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 earthen channels from stormwater-induced erosion. Critical elements of this protection are the ability of the RECP to: 1.1.1 Neutralize and absorb the hydraulic force of stormwater, thereby reducing soil particle loosening through “scour” mechanisms; 1.1.2 Slow runoff and encourage sedimentation, thereby reducing soil particle transport downstream; 1.1.3 Absorb shear forces of overland flow; 1.1.4 Trap soil particles beneath; and 1.1.5 Promote the establishment of vegetation. 1.2 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 prior to and after revegetation work. Further, procedures for evaluation of baseline conditions are provided. Thus, test preparation, test execution, data collection, data analysis and reporting procedures herein are intended to be suitable for testing of bare soil, unvegetated RECP, vegetated soil and vegetated RECP conditions. 1.3 This test method provides a comparative evaluation of an unvegetated RECP to baseline bare soil conditions and a vegetated RECP to a baseline, vegetated condition under controlled and documented conditions. 1.4 The values stated in SI units are to be regarded as standard. The inch-pound units given in parentheses are provided for information purposes only. 1.5 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. |
