The Slake Durability Apparatus is used in simulated weathering tests to determine abrasion resistance in wetting and drying cycles of shale and similar soft rocks in embankments and other construction-related applications. In the test, samples are alternately tumbled in mesh drums through a water medium and oven-dried for two cycles. The percent loss of mass is referred to as the Slake Durability Index.

The device consists of a double-ended motor drive unit which rotates two 5.5x3.9in (140mmx100mm) dia. sturdy wire mesh drums at twenty revolutions per minute in water tanks. Two water tanks are included with the apparatus and have built-in, quick-release drive units.

The 4ft (1,219mm) long base accommodates two additional Water Tanks and Drum Assemblies for increased productivity when testing. A set of two Wire Mesh Drums is also available separately to allow for more sample preparation.
