The type of geotextile to be used in a particular application shall be decided on the basis of design. Since the Geotextiles become integral part of any structure, whenever they are being used, it is necessary that the geotextile chosen should have sufficient strength to withstand the construction and other stresses, which a fabric is likely to bear during its life span. Table 700-1 specifies the minimum strength properties requirement for application in road works. The hydraulic properties requirement are given in the subsequent paragraphs. The properties specified are minimum average roll value in the weakest direction. The relevant test standards to determine the specified properties have also been indicated in the same table. The values given in the Table 700-1 are default values, which provide for sufficient survivability under most construction conditions. The Engineer based on engineering design, may specify properties other than those listed in the Table 700-1. Table 700-1 Geotextile strength property requirements Sl N o Geotextile Installation condition 1 Harsh installation condition 2 Moderate installation condition 3 Less severe installation condition Type of geotextile recommende d Grab strength in N as per ASTM D 4632 Strength property requirement * (MARV) Tear Puncture strength strength in N as pe in N as per ASTM ASTM D 4533 D D 4833 Burst strength in N as per ASTM 3786 Elongation at failure
Table 700-2 Geotextile Requirements for Ultra Violet Light Degradation S.No Properties of Fabric Test Methods Units Requirements (Retained Strength) 1 Grab Strength ASTMD 4632 N Not less than 50% 2 Tear Strength ASTMD 4533 N after 500 hrs of exposure 3 Puncture Strength ASTMD 4833 N 4 Burst Strength ASTMD 3786 kPa 701.2.2 Geogrid: Geogrid shall be made from integrally jointed, mono or bi- directionally oriented or stretched meshes made from polyethylene or polypropylene or polyester or similar polymer, with high secant modules, in square, rectangular, hexagonal or oval mesh form. Their junction strength shall be high with high creep resistance, and dimensional stability. Their open structure shall permit effective interlocking with soil, aggregates, rock etc. They shall be used as a tensile member or reinforcement. The following abbreviations and definitions are generally used with geogrids. CMD- Cross Machine Direction MD- Machine Direction UNIAXIAL GRID- A geogrid which has been manufactured with high junction strength and high tensile strength and modulus in one direction only. BIAXIAL GRID- A geogrid which has been manufactured with high tensile strength in two directions perpendicular to one another. DIRECTION OF REINFORCEMENT- Refers to the orientation that the geogrid is used for a particular project, which is along the machine direction (roll direction) for uniaxial geogrid. 701.2.3 Geonet : Geonet shall be made from a single extruded unoriented process from polyethylene or polypropylene or similar polymer. It shall have square or rectangular net shape aperture when used for protective works like gabions and mattresses. While in polygonal aperture it shall be used as a separator. It shall not be used as soil reinforcement due to its high creep characteristics, neither as a slope reinforcement or soil retaining wall or asphaltic reinforcement. Geonets used in protective works for highway structures shall be atleast 650 gm/sq.m in unit weight. It shall be black in colour, available in roll form in suitable width. 701.2.4 Geomembrane : Geomembrane shall be made from PVC or polyethelene sheets of atleast 0.8 mm thickness, duly protected from ultraviolet exposure with 2.5 per cent carbon black, in black colour, supplied in roll form with 3 m or above width. The joints of these sheets shall be heatbonded or seamed for effective permeation cut off, at site using standard equipment as part of the laying process. While fixing on to a slope, they shall not be punctured or stappled to impair their use. 701.2.5 Geocomposite: Geocomssites shall be made from combination of geonets, geogrids or geomembranes of above description using heat bonded, seamed stitched or wrap techniques. Their principal use shall be to regulate drainage in cross- plane or in-plane directions. Minimum unit weight of such material shall conform to the special provisions or as per Contract drawing. Prefabricated Vertical Drains (PVDs)/ Band Drains are a Geocomposite and they are widely used to accelerate the consolidation of soft soil. The minimum required specifications for the same are given below: Prefabricated vertical drains are made of geosynthetic materials. It consists of filter jacket surrounding a plastic core. The filter jacket or sleeve material consists of non woven geotextile made of polyester or polypropylene. The plastic core performs two vital functions i.e., it supports the filter jacket and it also provides path along the drain even at high lateral pressure. The PVDs should meet the following requirements to sustain the stresses during installation and to have compatibility of filter with the soil to be improved.
