1 1 STANDARDIZATION OF GEOSYNTHETICS

2 2  GEO-TEXTILES ARE FABRICS (WOVEN, NON-WOVEN, KNITTED OR COMPOSITES) USED IN, WITHIN OR BENEATH THE SOIL.  THESE CONSIST OF MAINLY THE TEXTILE MATERIALS MADE OF POLYESTER, POLYPROPYLENE, GLASS FIBRES, JUTE AND COIR.  JUTE AND COIR GEO-TEXTILES HAVE ADDITIONAL ADVANTAGE OF BEING ENVIRONMENT FRIENDLY AND BIODEGRADABLE WHICH ARE MAINLY USED FOR PREVENTION OF SOIL EROSION THROUGH VEGETATION.

3 3  GEO-TEXTILES HAVE A LARGE POTENTIAL FOR USE IN INDIA.  THE INDIAN RAILWAYS ALONE HAS IDENTIFIED ABOUT KM OF RAILWAY TRACK FOR STABILIZATION.  THE NATIONAL INTEGRATESD HIGHWAY PROJECT LAUNCHED BY THE PRIME MINISTER ENVISAGES ENORMOUS USE OF GEO-SYNTHETICS.  THESE PROJECTS HAVE LEAD TO HUGE DEMAND AND CONSUMPTION OF GEO-TEXTILES IN THE COUNTRY.

4 4 DEVELOPMENT OF STANDARDS ON GEO-SYNTHETICS IN INDIA

5 5 COMPANY STANDARDS COMPANY STANDARDS  IN INDIA VARIOUS STANDARDS ON GEO-SYNTHETICS WERE EARLIER ATTEMPTED AND PREPARED BY THE USER DEPARTMENTS TO A LIMITED EXTENT WHICH NORMALLY COVERED ONLY SPECIFIC REQUIREMENTS PERTAINING TO THEIR USE. – FOR EXAMPLE, THE MINISTRY OF ROAD TRANSPORT AND HIGHWAYS (MRT&H) AND INDIAN ROADS CONGRESS (IRC) HAVE EVOLVED THE STANDARDS RELATED TO USE OF GEO- SYNTHETICS FOR ROAD, ROAD PAVEMENT, BRIDGE WORKS ETC. – SIMILARLY RDSO HAS EVOLVED STANDARDS RELATED TO USE OF GEO-SYNTHETICS FOR RAIL BED STABILIZATION.

6 6 N ATIONAL STANDARDIZATION N ATIONAL STANDARDIZATION

7 7 A SYSTEMATIC APPROACH FOR STANDARDIZATION OF GEO-SYNTHETICS AT NATIONAL LEVEL WAS FIRST ADOPTED BY BIS IN LATE 1980S THROUGH A NETWORK OF TWO TECHNICAL COMMITTEES, A SYSTEMATIC APPROACH FOR STANDARDIZATION OF GEO-SYNTHETICS AT NATIONAL LEVEL WAS FIRST ADOPTED BY BIS IN LATE 1980S THROUGH A NETWORK OF TWO TECHNICAL COMMITTEES,  GEO-TEXTILES AND INDUSTRIAL FABRICS SECTIONAL COMMITTEE, TX 30 AND  GEO-SYNTHETICS SECTIONAL COMMITTEE, WRD 25. TX 30 IS LOOKING AFTER STANDARDIZATION WORK RELATED TO TESTING AND SPECIFICATION REQUIREMENTS FOR GEO-TEXTILES MADE OF POLYESTER, POLYPROPYLENE, JUTE, COIR AND OTHER FIBRES HAVING WOVEN/NON-WOVEN/KNITTED STRUCTURE WHILE WRD 25 MAINLY COVERS GEO-MEMBRANES/GEO-GRIDS/GEO-COMPOSITES AND ALLIED PRODUCTS (NATURAL AND POLYMERIC) FOR RIVER VALLEY AND OTHER CIVIL ENGINEERING RELATED APPLICATIONS. OF LATE WRD 25 HAS BEEN MERGED WITH TX 30 OF LATE WRD 25 HAS BEEN MERGED WITH TX 30

8 8  A PROPERLY DESIGNED GEO-SYNTHETIC MATERIAL IS BELIEVED TO PERFORM THE FOLLOWING FUNCTIONS SEPARATELY OR IN CONJUNCTION, IN DIFFERENT APPLICATION AREAS: –SEPARATION –FILTRATION AND DRAINAGE –INITIAL REINFORCEMENT –CONTROL OF SURFACE SOIL DETACHMENT –VEGETATION OR BIO-TECHNICAL SUPPORT

9 9 NEED FOR TESTING  PRODUCTS ARE TESTED FOR THE FOLLOWING REASONS: * QUALITY ASSURANCE AND CONTROL * SETTING AND MAINTAINING PERFORMANCE STANDARDS STANDARDS * INVESTIGATION OF COMPLAINTS * INVESTIGATION OF COMPLAINTS * PRODUCT DEVELOPMENTS AND RESEARCH * PRODUCT DEVELOPMENTS AND RESEARCH

10 10  THE FOLLOWING PROPERTIES OF GEO- SYNTHETICS ARE IMPORTANT FROM THE VIEWPOINT OF PERFORMANCE OF GEO-TEXTILES DURING USE :

11 11  APPARENT OPENING SIZE  WATER PERMITTIVITY  WATER TRANSMITTIVITY  CREEP BEHAVIOUR  PUNCTURE RESISTANCE  ABRASION RESISTANCE  THICKNESS AT SPECIFIED PRESSURES  MASS PER UNIT AREA  TENSILE PROPERTIES  TEAR STRENGTH  MICROBIAL RESISTANCE  RESISTANCE TO WEATHERING (UV LIGHT, WATER AND HEAT)  JOINT/SEAM STRENGTH,  THICKNESS ETC.

12 12  GEO-TEXTILES HAVE SPECIFIC CONSTRUCTIONS AND WORK IN SPECIFIC SOIL CONDITIONS AND END USES, THE TEST METHODS USED FOR ORDINARY TEXTILES ARE NOT APPLICABLE TO THEM.  THE DEGREE OF BENEFITS OFFERED BY GEO- TEXTILE MATERIALS TO SOIL FABRIC AGGREGATE SYSTEM DEPENDS TO A LARGE EXTENT ON THE PROPERTIES OF THE SOIL AS WELL AS THE FABRIC USED  KEEPING THIS IN VIEW, BIS HAS PUBLISHED INDIAN STANDARDS ON GEO-SYNTHETICS

13 13  IS 13321(PT 1): 1992 GLOSSARY OF TERMS FOR GEO- SYNTHETICS, PART I TERMS USED IN MATERIALS AND PROPERTIES THIS STANDARD IS COMPILATION OF THE TERMS RELATING TO MATERIAL AND PROPERTIES, LIKE ABSORPTION, APPARENT OPENING SIZE, BIO- DEGRADABILITY, BONDING, BREAKING LOAD, TOUGHNESS, CHEMICALLY BONDED NON-WOVEN FABRIC, CLOGGING, COATED FABRICS, COMPRESSED THICKNESS, DISCONTINUOUS FIBRE, ELASTIC LIMIT, EXTRUDED MESH, EXTRUDER FABRIC, COMPOSITE, FABRIC KNIT, FABRIC NON-WOVEN, BREAKING LOAD, GEO-CELL, GEO- COMPOSITE, GEO-GRID, GEO-MEMBRANE, INDEX TEST, INITIAL TENSILE MODULUS, OFFSET, TENSILE MODULUS, STIFFNESS.

14 14  IS 13326(PT 1): METHOD OF TEST FOR THE EVALUATION OF INTERFACE FRICTION BETWEEN GEO- SYNTHETICS AND SOIL PART I MODIFIED DIRECT SHEAR TECHNIQUE THIS STANDARD PROVIDES DETAILS ON TEST METHODS FOR DETERMINATION OF COEFFICIENT OF INTERFACE FRICTION BETWEEN A GIVEN SOIL (INCLUDING AGGREGATE AND BALLAST) AND A GEO-SYNTHETIC USED FOR REINFORCEMENT PURPOSES. THIS METHOD IS ALSO APPLICABLE FOR ASSESSING THE FRICTION BETWEEN A GEO-MEMBRANE AND THE NATURAL OR COMPACTED SOIL IN ORDER TO ANALYZE THE STABILITY OF THE CANAL/RESERVOIR LINING.

15 15  IS 14986:2001 GUIDELINES FOR APPLICATION OF JUTE GEO-TEXTILE FOR RAIN WATER EROSION CONTROL IN ROAD AND RAILWAY EMBANKMENT AND HILL SLOPES THIS STANDARD HAS BEEN PREPARED BASED ON THE DATA PROVIDED BY THE INDIGENOUS MANUFACTURERS AND TAKING INTO CONSIDERATION THE PRACTICE PREVALENT IN INDIA. THE SPECIFIC REQUIREMENTS, SELECTION, INSTALLATION METHOD, MONITORING AND REQUIREMENT OF PACKING HAVE BEEN COVERED IN THIS STANDARD

16 16  IS 13162(PT 2):1991 GEO-TEXTILES - METHODS OF TEST PART 2: DETERMINATION OF RESISTANCE TO EXPOSURE OF ULTRA-VIOLET LIGHT AND WATER (XENON ARC TYPE) THIS STANDARD PRESCRIBES A METHOD FOR THE DETERMINATION OF RESISTANCE OF GEO- TEXTILES TO THE EXPOSURE OF ULTRAVIOLET LIGHT AND WATER. THE LIGHT AND WATER EXPOSURE APPARATUS EMPLOYS A XENON-ARC LIGHT SOURCE.

17 17  Geo-textiles are manufactured using a variety of processes and formulations of polymers and each geo- textile varies in its sensitivity to ultraviolet radiation. Ultraviolet radiation from the sun varies with duration of exposure, angle of inclination of the sun, atmospheric conditions, topography, and geography. The Xenon-arc test cannot simulate all these variables, so it is not likely that Xenon-arc test results will relate directly to sunlight exposure test results for a specific fabric at a given site.  The method prescribed is suitable for comparative evaluation of geotextiles and is not recommended for acceptance testing of commercial shipments since information on inter-laboratory precision is incomplete.

18 18  IS (PT 3): 1992 GEO-TEXTILES - METHODS OF TEST PART 3: DETERMINATION OF THICKNESS AT SPECIFIED PRESSURE THIS STANDARD PRESCRIBES TWO METHODS FOR DETERMINATION OF THE THICKNESS OF GEO-TEXTILES AT SPECIFIED PRESSURES AND DEFINES AT WHICH PRESSURE THE NOMINAL THICKNESS IS DETERMINED. METHOD A ( LOADING EACH SET OF SPECIMENS ) SHALL BE USED WHEN USING AN APPARATUS THE CONSTRUCTION OF WHICH CAUSES A HIGH DEGREE OF TIME AND/OR LABOUR WHEN CHANGING THE PRESSURE, OTHERWISE METHOD B (INCREMENTAL LOADING OF INDIVIDUAL SPECIMENS ) SHALL BE USED. THE METHOD IS APPLICABLE TO ALL TYPES OF GEO-TEXTILES.

19 19  Since the geotextiles are compressible, the thickness measure will depend upon the pressure applied. For this reason it may be desirable to measure thickness at a series of pressures and to study the general relationship between thickness and pressure.

20 20  IS (PT 4): 1992 GEO-TEXTILES - METHODS OF TEST PART 4: DETERMINATION OF PUNCTURE RESISTANCE BY FALLING CONE METHOD Geotextiles used as separator and filter in earth constructions are normally subjected to dynamic impact. During the installation process, crushed rock or boulders are dropped onto a fabric supported by weak, water-saturated soil which may penetrate and thus damage the geotextile. It is, therefore, desirable that the geotextiles should resist the sudden impact and penetration of such particles.

21 21 THIS STANDARD PRESCRIBES A METHOD FOR DETERMINATION OF THE SIZE OF THE HOLE MADE BY DROPPING A STANDARD BRASS CONE ONTO A GEO-TEXTILE, SUPPORTED BY WATER, AND TO PROVIDE AN INDICATION OF THE ABILITY OF THAT FABRIC TO RESIST A SUDDEN IMPACT. THIS STANDARD PRESCRIBES A METHOD FOR DETERMINATION OF THE SIZE OF THE HOLE MADE BY DROPPING A STANDARD BRASS CONE ONTO A GEO-TEXTILE, SUPPORTED BY WATER, AND TO PROVIDE AN INDICATION OF THE ABILITY OF THAT FABRIC TO RESIST A SUDDEN IMPACT.

22 22  IS (PT 5): 1991 GEO-TEXTILES - METHODS OF TEST PART 5: DETERMINATION OF TENSILE PROPERTIES USING A WIDE WIDTH STRIP THIS STANDARD PRESCRIBES AN INDEX TEST METHOD FOR DETERMINATION OF THE TENSILE PROPERTIES OF GEO-TEXTILES AND RELATED PRODUCTS USING A WIDE WIDTH STRIP. THE METHOD IS APPLICABLE TO MOST GEO-TEXTILES INCLUDING WOVEN FABRICS, NON-WOVENS, LAYERED FABRICS, KNITTED FABRICS AND FELTS. THE METHOD IS APPLICABLE TO GEO-GRIDS BUT THE SPECIMEN DIMENSIONS MAY NEED TO BE ALTERED. THIS METHOD COVERS THE MEASUREMENT OF LOAD ELONGATION CHARACTERISTICS AND INCLUDES PROCEDURES FOR CALCULATION OF SECANT STIFFNESS, MAXIMUM-LOAD PER UNIT WIDTH, STRAIN AT MAXIMUM LOAD AND EQUIVALENT STRAIN AT MAXIMUM LOAD. PROCEDURES FOR MEASURING THE TENSILE PROPERTIES OF BOTH CONDITIONED AND WET SPECIMENS ARE INCLUDED. THE MEASURING DEVICE CAN BE EITHER MECHANICAL, OPTICAL OR INFRA-RED.

23 23 The basic distinction between this method and other methods for measuring tensile properties of fabrics, is the width of the specimen. This width by contrast is greater than the length of the specimen. Some geotextiles have a tendency to contract ( neck down ) under load in the gauge length area. The width of the specimen specified in this method reduces the contraction effect of those fabrics and provides a closer relationship to expected fabric behaviour in the field and a standard comparision of geotextiles.

24 24  IS 14293: 1995 GEO-TEXTILES - METHODS OF TEST FOR TRAPEZOID TEARING STRENGTH THIS TEST METHOD IS USED TO MEASURE THE TEARING STRENGTH OF WOVEN OR NON-WOVEN GEO-TEXTILES BY THE TRAPEZOID METHOD. THIS TEST METHOD MAY BE USED WITH CONSTANT RATE OF- TRAVERSE (CRT) OR CONSTANT-RATE-OF-EXTENSION (CRE) TYPE TENSION MACHINES. HOWEVER, THERE MAY BE NO OVERALL CORRELATION BETWEEN THE RESULTS OBTAINED WITH THE CRT MACHINE AND THE CRE MACHINE. CONSEQUENTLY, THESE TWO TENSION TESTERS CANNOT BE USED INTERCHANGEABLY. IN CASE OF CONTROVERSY, THE CRE MACHINE SHALL PREVAIL.

25 25  IS 14294: 1995 GEO-TEXTILES - METHOD FOR DETERMINATION OF APPARENT OPENING SIZE BY DRY SIEVING TECHNIQUES THIS INDIAN STANDARD SPECIFIES METHOD TO DETERMINE APPARENT OPENING SIZE (AOS) BY DRY SIEVING TECHNIQUE. THIS METHOD IS SUITABLE FOR AOS 60 MICRONS AND ABOVE.

THE STANDARD COVERS TWO PROCEDURES -THE CONSTANT HEAD METHOD AND THE FALLING HEAD METHOD.

27 27  IS 14706:1999 GEO-TEXTILES - SAMPLING AND PREPARATION OF TEST SPECIMEN THIS INDIAN STANDARD PROVIDES GENERAL PRINCIPLES FOR SAMPLING OF GEO- TEXTILES AND PREPARATION OF TEST SPECIMENS FROM THE SAMPLES. THE PRINCIPLES ARE APPLICABLE TO ALL GEO- TEXTILES SUPPLIED IN ROLLS.

28 28  IS 14714:1999 GEO-TEXTILES - DETERMINATION OF ABRASION RESISTANCE THIS TEST METHOD COVERS DETERMINATION OF RESISTANCE OF GEO- TEXTILES TO ABRASION USING AN ABRASION TESTER. THE TEST METHOD IS APPLICABLE TO ALL GEO-TEXTILES AND IS NOT SUITABLE FOR GEO-SYNTHETICS.

29 29  IS 14715:2000 GEO-TEXTILES - GEO-JUTE FABRICS (JUTE GEO-TEXTILES) WOVEN - SPECIFICATION THE STANDARD PRESCRIBES CONSTRUCTIONAL DETAILS AND OTHER DETAILS OF WOVEN JUTE GEO- TEXTILES. WOVEN JUTE GEO-TEXTILES ARE USED FOR STABILIZATION OF SOIL THROUGH VEGETATION AGAINST EROSION OF LANDSCAPE AND SOIL SLOPES AS WELL AS PROTECTION OF RIVER BANK AGAINST EROSION AND SIMILAR APPLICATIONS INVOLVING SEPARATION AND FILTRATION. THE STANDARD IS BASED ON WORK DONE BY INDIAN JUTE INDUSTRY’S RESEARCH ASSOCIATION, CALCUTTA IN THIS FIELD.

30 30  IS 14716:1999 GEO-TEXTILES - DETERMINATION OF MASS PER UNIT AREA THIS STANDARD SPECIFIES A METHOD FOR THE DETERMINATION OF THE MASS PER UNIT AREA OF GEO-TEXTILES FOR IDENTIFICATION PURPOSES AND FOR USE IN TECHNICAL DATA SHEETS.

31 31  IS 14739:1999 GEO-TEXTILES - METHOD FOR DETERMINATION OF CREEP THIS STANDARD DESCRIBES A METHOD FOR DETERMINING THE LOAD-STRAIN- TIME RELATIONSHIP OF GEO-TEXTILES AT A GIVEN TEMPERATURE FROM A SERIES OF CONSTANT LOAD TESTS.

32 32  IS 15060:2001 GEO-TEXTILES - TENSILE TEST FOR JOINTS/SEAMS BY WIDE WIDTH METHOD THIS STANDARD SPECIFIES AN INDEX TEST METHOD FOR DETERMINATION OF THE TENSILE PROPERTIES OF JOINTS AND SEAMS IN GEO-TEXTILES AND RELATED PRODUCTS, USING A WIDE-WIDTH STRIP. THE METHOD IS APPLICABLE TO MOST GEO-TEXTILES AND GEO-TEXTILE-RELATED PRODUCTS. IT IS ALSO APPLICABLE TO GEO-GRIDS, BUT THE SPECIMEN DIMENSIONS MAY NEED TO BE ALTERED. PROCEDURES FOR MEASURING THE TENSILE PROPERTIES OF BOTH CONDITIONED AND WET SPECIMENS ARE INCLUDED. SOME MODIFICATION OF TECHNIQUES MAY BE NECESSARY FOR PARTICULAR GEO-TEXTILES, E.G. STRONG GEO-TEXTILES, MESHES OR GEO-TEXTILES MADE FROM GLASS FIBRE, TO PREVENT THEM FROM SLIPPING IN THE JAWS OR BEING DAMAGED AS A RESULT OF BEING GRIPPED IN THE JAWS. THE BASIC TEST FOR JOINTS OR SEAMS IN ALL KINDS OF GEO-TEXTILES OR RELATED PRODUCTS USES TEST SPECIMENS OF 200 MM WIDTH, WITH THE PROVISION FOR THE SEAM OR JOINT TO EXTEND FOR 25 MM ON EACH SIDE IN ORDER TO PROVIDE JOINT OR SEAM STABILITY DURING THE TEST.
