Description of Test

The dry aggregate sample is separated into a series of particle size fractions (e.g., 3/8" to 3/4"). Each fraction is covered with water for about 24-hours. The particles are then individually rolled and squeezed between the thumb and forefinger in an attempt to break the particles. The particles are then washed, dried and weighed.
