• <br />STANDARD SPECIFICATION <br />FOR <br />ROLLED EROSION CONTROL PRODUCTS <br />This work consists of constructing temporary and permanent installations to control erosion, enhance <br />vegetation establishment, and survivability on slopes, channels, and includes installing rolled erosion <br />control products. <br />Temporary Rolled Erosion Control Products <br />For applications where natural vegetation alone will provide sufficient permanent erosion protection, <br />furnish a temporary rolled erosion control product with the necessary longevity and performance <br />properties to effectively control erosion and assist in the establishment of vegetation under the anticipated <br />immediate site conditions. The temporary rolled erosion control product shall conform to one of the <br />following specifications and corresponding properties found in Table 1. <br />Permanent Rolled Erosion Control Products <br />For applications where natural vegetation alone will not sustain expected flow conditions and/or provide <br />sufficient long-term erosion protection, furnish a permanent rolled erosion control product with the <br />necessary performance properties to effectively control erosion and reinforce vegetation under the <br />expected long-term site conditions. The permanent erosion control product shall conform to one of the <br />specifications and corresponding properties found in Table 2. <br />Rolled erosion control products are designated as follows: <br />(a) Mulch control netting. A planar woven natural fiber or extruded geosynthetic mesh used as a <br />temporary degradable rolled erosion control product to anchor loose fiber mulches. <br />(b) Open weave textile. A temporary degradable rolled erosion control product composed of <br />processed natural or polymer yarns woven into a matrix, used to provide erosion control and <br />facilitate vegetation establishment. <br />(c} Erosion control blanket. A temporary degradable rolled erosion control product composed of <br />processed natural or polymer fibers mechanically, structurally or chemically bound together to <br />form a continuous matrix to provide erosion control and facilitate vegetation establishment. <br />(d) Turf reinforcement mat. A rolled erosion control product composed ofnon-degradable <br />synthetic fibers, filaments, nets, wire mesh and/or other elements, processed into a permanent, <br />three-dimensional matrix of sufficient thickness. TRMs, which maybe supplemented with <br />degradable components, are designed to impart immediate erosion protection, enhance <br />vegetation establishment and provide long-term functionality by permanently reinforcing <br />vegetation during and after maturation. Note: TRMs are typically used in hydraulic <br />applications, such as high flow ditches and channels, steep slopes, stream banks, and <br />shorelines, where erosive forces may exceed the limits of natural, unreinforced vegetation or <br />in areas where limited vegetation establishment is anticipated. <br />• <br />ECTC /Final 060004 /version 5.0 <br />© Erosion Control Technology Counci12006 <br />Rev. 083006 <br />
