    New Test Method for Determination of Erosion Control Products (ECP) Performance in Protecting Slopes from Rainfall-Induced Erosion Using a Tilted Bed Slope

    (What is a Work Item?)

    Developed by Subcommittee: D18.25 | Committee D18 | Contact Staff Manager


    1. Scope

    1.1 This test method is used to evaluate the ability of erosion control products (ECP) to protect slopes from rainfall-induced erosion using an adjustable tilting bed slope. There are three main elements the ECPs shall have the ability to perform: (1) absorb the impact force of raindrops, thereby reducing soil particle loosening and detachment through splash mechanisms; (2) slow runoff and encourage infiltration, thereby reducing soil particle displacement and transport through overland flow mechanisms; and (3) trap soil particles beneath the ECP. 1.2 The results of this test method can be used to evaluate performance and acceptability and can be used to compare the effectiveness of different ECPs. This test method provides a comparative evaluation of an ECP to baseline bare soil conditions under controlled and documented conditions. 1.3 This test method covers the use of three different soil types, ECP installation: sprayed, rolled, or dry applied and three runoff collection procedures. 1.4 This test method uses large-scale testing equipment and procedures established at a variety of testing laboratories over the last 30 years. This test is typically performed indoors but may be performed outside as long as certain requirements are met. 1.5 Units-The values stated in SI units are to be regarded as the standard. The values given in parentheses are mathematical conversions to inch-pound units, which are provided for information only and are not considered standard. Reporting of test results in units other than SI shall not be regarded as nonconformance with this standard. 1.5.1 The converted inch-pound units use the gravitational system of units. In the system, the pound (lbf) represents a unit of force (weight), while the units for mass is slugs. The converted slug unit is not given unless dynamic (F = ma) calculations are involved. 1.6 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026, unless superseded by this test method. 1.6.1 The procedures used to specify how data are collected/recorded and calculated in the standard are regarded as the industry standard.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 users 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 these test methods to consider significant digits used in analysis methods for engineering data. 1.7 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. 1.8 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.
