The bucket will rotate 600 times at a speed of 58-62 rpm, for approximately 10 minutes. After the rotation is complete the mass of the remaining aggregate is weighed and compared with the original weight to determine the WBM value. A lower value will indicate a tougher aggregate more resistant to abrasion, essential to a quality base.
