【国外标准】 Standard Practice for Construction of Live Fascines on Slopes (Withdrawn 2023)

4.1 Live fascines are used to provide erosion and sedimentation control by increasing infiltration, slowing or redirecting runoff, and trapping seed and sediments. The method provides shallow mechanical surface slope stabilization, and provides enhanced values through vegetative growth and additional shallow soil reinforcement through the development of the roots. The ability of live fascines to function properly depends on the quality and choice of the materials used to construct the live fascine, the means and methods of fabrication and installation, and proper consideration of site characteristics and time of year. For the live fascine to function completely, it is important that the live fascine develops suitable growth.1.1 This practice covers the material, fabrication and installation work to construct live fascines.1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.1.3 This practice offers a set of instructions for performing one or more specific operations. This document cannot replace education or experience and should be used in conjunction with professional judgement. Not all aspects of this practice may be applicable in all circumstances. This ASTM standard is not intended to represent or replace standard of care by which the adequacy of a given professional service must be judged, nor should this document be applied without considerations 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.1.4 This standard may involve hazardous materials, operations, and equipment. 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.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.
