Test Method Title
Standard Test Method for Measuring the Nominal Thickness of Geosynthetics
Reference Number
ASTM D5199
Material
Geocomposite, Geonet
Test Property
nominal thickness
Description of Test
The nominal thickness of geosynthetics is determined by observing the perpendicular distance that a movable plane is displaced from a parallel surface by the geotextile or geomembrane material while under a specified pressure (2 kPa for geotextiles and 20 kPa for geomembranes for 5s).
