Application
Application of Dry Sieve Test Apparatus
Dry Sieve Test Apparatus is used to determine the apparent/equivalent opening size of a geotextile by sieving sized glass beads through the geotextile, using the dry-sieve principle. 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. The apparent opening size (O90/O95) of the geotextile corresponds to a specified size of graded glass beads passed (d90/d95).
Dry Sieve Analysis Test complies with ASTM D4751 etc international and retailer standards.
