Mirafi® RSi-Series Woven Geosynthetics Pavement Base Reinforcement & Subgrade Stabilization Protective Fabrics Space Composites Aerospace Composites Advanced Armour Geosynthetics Industrial Fabrics Grass RS580i RS380i Pavement Base Reinforcement & Subgrade Stabilization ® TenCate Mirafi RSi-Series will revolutionize the way you look at geosynthetics for roadway stabilization. As the leader in geosynthetic solutions, TenCate began the extensive research and design process of looking for the ‘perfect’ geotextile that could move more water while concurrently retaining more soil within a roadway system. This product would also need to hold more force with less overall system movement in order to improve the base strength and support heavier loads; thus, resulting in longer life, less maintenance and costs, and ® better performance. The solution we developed…Mirafi RSi. SUPERIOR INTEGRATION Integration of a superior multi-layered construction of woven fibers of various dimensions specifically positioned relative to adjoining fibers to create three times the water flow and an increase in AOS sieve size. THE DIFFERENCE ® The difference Mirafi RSi-Series Woven Integrated* Geosynthetics make: Modulus. Separation. Confinement. Water flow. Product identification. Reinforcement Strength. Higher tensile modulus properties than the leading stabilization products. Separation and Filtration. Unique double layer construction provides an excellent separation factor with superior filtration and drainage. Uniform openings provide consistent filtration and flow characteristics of a fine to coarse sand layer. Soil and Base Course Interaction. Excellent soil and base course confinement resulting in greater load distribution. Durability. Robust damage resistance for moderate to severe stress installations. Roll Sizes. Mirafi® RSi-Series geosynthetics come in several roll sizes to fit project requirements. Seams. Panels can be seamed in the factory or field, providing cross-roll direction strength to facilitate efficient installation. APPLICATIONS ® When superior performance, flexibility and versatility are necessary, Mirafi RSi-Series geosynthetics make the difference for varying application needs including: Base course reinforcement and subgrade stabilization for road Runway and railway construction Embankment stabilization on soft foundations Reinforcement for mechanically stabilized earth (MSE) structures Line support Voids bridging Reinforcement over soft hazardous pond closures Other environmental market applications Comparative Traffic Benefit Ratios TBR TBR TBR Mirafi RS580i 4.1 10.8 14.8 Extruded PP Geogrid 3.4 7.9 10.4 Welded Tape Geogrid 3.0 6.6 8.4 Knitted PET Geogrid 2.6 5.1 6.3 Extruded Multi Axial Triangular Grid PP 1 2.4 4.3 5.2 Extruded Multi Axial Triangular Grid PP 2 1.9 2.9 3.4 Knitted PP Geogrid 1.6 2.3 2.5 25mm Rut Depth 50mm Rut Depth 63mm Rut Depth Data extracted from Report on Relative Operational Performance of Geosynthetics used as Subgrade Stabilization, by Western Transportation Institute, College of Engineering, Montana State University for Montana Department of Transport. 2 | Mirafi® RSi-Series Woven Geosynthetics INSTALLATION GUIDELINES Geosynthetic Placement Place the geosynthetic directly on prepared surface. It is advisable to leave vegetative cover in place to provide a support matting for construction activities. The geosynthetic should be deployed flat and tight with no wrinkles or folds. The rolls should be oriented as shown on plans to insure the principal strength direction of the material is placed in the correct orientation. Adjacent rolls should be overlapped or seamed as a function of subgrade strength (CBR). Prior to fill placement, Mirafi® RSi geosynthetics should be held in place using suitable means such as pins, soil, staples and sandbags to limit movement during fill placement. Fill Placement Fill should be placed directly over Mirafi® RSi geosynthetics in 200mm to 300mm loose lifts. For very weak subgrades, 450mm lifts or thicker may be required to stabilize the subgrade. Most rubber-tired vehicles can be driven at slow speeds, less than 16km/h and in straight paths over the exposed geosynthetic without causing damage. Sudden braking and sharp turning should be avoided. Tracked construction equipment should not be operated directly upon the geosynthetic. A minimum fill soil thickness of 15cm is required prior to operation of tracked vehicles over the geosynthetic. Turning of tracked vehicles should be kept to a minimum to prevent tracks from displacing the fill and damaging the geotextile. Advantages Go to www.mirafi.com for product demonstrations video. Product Identification Typical Woven Geotextile Mirafi® RS580i Geogrids vs. Mirafi ® RS580i Strength at Every Angle Go with the Flow Walk the Walk * Integration refers to the overall set of described characteristics based on a review of technical specifications for comparable products published by their respective manufacturers. Individual characteristics of these products vary and may meet, exceed, and fall below one or more of the above described individual characteristics. These guidelines serve as a general basis for installation. Detailed instruction are available from your TenCate representative.
