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
