There are three material gradation requirements based on required rock layer thicknesses. endstream Close observation is required during rock placement to detect any damage to the fabric. For RSP Classes IX thru XI, use Class 10 RSP-fabric. Mirafi 140N is a lightweight non woven geotextile that meets AASHTO M288 Class 3 geotextiles for separation and subsurface drainage. This work consists of protecting slopes, channels, and gutters with riprap, interlock precast concrete blocks, concrete, grouted items, tied concrete block mats, crushed aggregate, or rock items. If you have any questions about the consistency of the gabions, you may also order the unit weight to be verified during the course of the work. When slope paving with concrete pavers is specified, ensure the special provision requirements are met. Mirafi N-Series nonwovens combine high water flow rates, high soil interaction and durability while providing excellent soil particle retention. RSP-fabric Type of geotextile and quality requirements per Section 96 Rock Slope Protection Fabric of the Standard Specifications. (b) Paving fabric specification requires a minimum mass of 4.1 sy/oz. There are three material gradation requirements based on required rock layer thicknesses. Riprap can be used to stabilize slopes to prevent erosion and provide support. If there are no prevailing agency specifications, it is recommended to follow AASHTO M288 for subsurface drainage applications. Whether you're speeding down a slope or cycling uphill, the F5 can be worn in a number of ways to fit your training and needs. <> If the slope is steeper than 2:1, do not use rounded boulders and cobbles.
