Geotextile Opening Size Tester (Dry Sieving), to determine the apparent opening size (AOS) of a geotextile by sieving glass beads pass through a geotextile sample.
A geotextile specimen is placed in a sieve frame, and sized glass beads are placed on the geotextile surface. The geotextile and frame are shaken laterally so that the jarring motion will induce the beads to pass through the test specimen. The procedure is repeated on the same specimen with various size glass beads until its apparent opening size has been determined.
