Product Description

ASTM TRANSMISSIVITY

DESIGNED TO TEST THE TRANSMISSIVITY IN-PLANE FLOW) CHARACTERISTICS OF GEOSYNTHETIC DRAINAGE MATERIAL PROFILES

AIR RAM LOADING HYDRAULIC TRANSMISSIVITY DEVICE
(IN PLANE FLOW ASTM D 4716

  • A Steel Framework Table supporting one Test Station With Adjustable Legs for leveling the device
  • Aluminum Modular Test Box Assembly
  • 12″ X 12″ Test Area (Samples up to 18″ long)
  • Up to 2″ Profile Height (CEN requires 11cm)
  • Platen Removal Assist Device can be adjusted to allow sample loading from the downstream end Aluminum platen w/sealing mechanism activated during
    measurement to control fugitive flow (with mating radii on upstream bridge plate and platen to enhance sealing)
  • Upstream head reservoirs w/adjustable head tube
  • Downstream reservoirs w/profile threshold
  • Manometers to indicate gradient with ports in the test box and upstream and downstream reservoirs (mm or 0.1″) 0 to 1+ gradient (gradient measured via sight
    manometer with scale (0.0″ or 1.0 mm resolution)
  • Circulation systems for each device including pump throttle valve, plastic catch tank and hoses
  • Compressive loads from 250 to 5,000, 10,000 or 500 to 20,000* ,30,000 psf using a multi-stage linear air system to deliver and maintain the Compressive Load
