(1) Virginia Department of Highways and Transportation test method.
(2) 8" wide x 4" length (200 x 100 mm) specimen tested at a strain rate of 10% (0.4 inch) (10 mm) per minute.
(3) Using 5/16" (8 mm) diameter flat tipped steel cylinder centered with ring clamp.
(4) Non-stabilized or low susceptible geotextiles should not be exposed to ultraviolet radiation for more than 5 days.
(5) American Association of Textile Chemists and Colorists test procedures.
(6) Permeability Coefficient (ASTM D 4491)
    (a) Joints for concrete pipe culverts & RC boxes, edge drains, drainage tubing, etc. Used as a general filtration fabric.
    (b) Riprap, gabions, inslopes retention on MSE backfill, etc. Use-same as (a) except has a higher construction loading.
    (c) Medians, ditches, channels, etc. Used to minimize erosion.
    (d) Medians , ditches, slopes, etc. Used to filter sediment laden water.
    (e) Subgrades, embankments, etc. Used to separate granular material from subgrade.
    (f) Bridge End Backfill and reinforced slopes. Used to create a reinforced fill and/or used as the wall facing material.
    (g) Under pavements. Used to restrict the flow of fluids to underlying materials.
