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
