Sediment Retention Fiber Rolls
A proposed new ASTM standard is being developed to measure the basic physical properties of sediment retention fiber rolls, known as SRFRs. SRFRs are used to inhibit the migration of sediment that has been displaced and carried by flowing water.
The proposed standard, WK39691, Test Methods for Determining Index Height, Diameter, Length and Mass per Unit Length of a Sediment Retention Fiber Roll (SRFR), is being developed by Subcommittee D18.25 on Erosion and Sediment Control Technology, part of ASTM International Committee D18 on Soil and Rock.
According to C. Joel Sprague, senior engineer, TRI/Environmental Inc., and a D18.25 member, the proposed test method is needed for performing quality control and quality assurance testing on SRFRs. Once it has been approved, the proposed standard will be used by manufacturers to perform and document quality control in the manufacturing process, as well as by end users who will rely on test results to assess specification conformance.
Sprague notes that the Erosion Control Technology Council defines sediment retention fiber rolls as manufactured three-dimensional devices of specified filler matrix encapsulated within a flexible containment material utilized in sediment and flow control applications. SRFRs are also known as wattles, logs, socks, tubes or fiber rolls.
Subcommittee D18.25 welcomes interest in its standards developing activities, particularly from designers and regulators of stormwater quality projects. The task group developing WK39691 is also working on developing terminology and performance tests associated with sediment retention devices.
