1. General
1.0.1 This regulation is formulated to boost geosynthetic application in highway engineering, regulate and unify material test method.
1.0.2 This regulation is applicable to all kinds of geosynthetic performance test in highway engineering.
1.0.3 Instrument and equipments used in this regulation shall be verified by measurement service or feeler mechanism. regular correction is also necessary.
1.0.4 Government statutory unit of measurement shall be used.
1.0.5 Standards contain provisions which, through reference in this text, constitute
provisions of this standard.
1.0.6 Highway engineering geosynthetic performance test, not only meeting this
regulation, shall also conform to current relevant standard of the nation; as for test items not stipulated in this regulation, domestic and foreign standards can be referred to, but it shall be indicated in the test report.
2. Terminology and symbol
2.1 Terminology
2.1.1 Geosynthetics
Collection of geotextile, geomembrane, geocomposite and earth work special type
material used in geotechnical engineering and civil engineering.
2.1.2 Geotextile
Penetrable polymeric material used in geotechnical engineering, civil weaving, knitting
or non-weaving.
2.1.3 Geogrid
Regular reticulation tensile strip formed geosynthetics used for reinforcement. Open pore thereof can be penetrated by around soil, stone or other geomaterials.
2.1.4 Geonet
Geosynthetics formed by parallel ribs bonding of different angle with same ribs to be
used in plane drainage and venting.
2.1.5 Geomembrane
Relative waterproof film made of polymeric compound or asphalt.
2.1.6 Geocomposite
Geosynthetics made of two or more than two materials.
2.1.7 Tensile strength
Per unit width maximum pull when the sample is stretched to fracture in the test.
2.1.8 Elongation
Strain capacity corresponding to the maximum pull; percentage is the unit.
2.1.9 Tearing strength
Sample between two clampers are in the ladder-type; maximum force that tear the
ladder-type sample.
