(breaking down asphalt)

Laboratory analysis of aggregate samples requires complete separation of the random sample content. Ultrasonic stimulation will provide complete separation of the mixture quickly and cleanly.


  1. Fill the main tank 2/3 full with General Purpose Cleaner Non-Ammoniated (PC228)diluted per label instructions. This will be used as a carrier bath.
  2. Place Auxiliary Pan containing Ultrasonic Instrument Rinsing Solution (PC197) in the main tank (double boiler fashion).
  3. Place asphalt sample (3x3x2) in Stainless Steel Basket in the Auxiliary Pan.
  4. Cavitate 8 to 15 minutes.
  5. Sand and gravel particles on the bottom of the Auxiliary Pan should be stirred occasionally to insure maximum cavitation.
  6. Pour off dirty solution from Auxiliary Pan.
  7. Using a series of fine sifters, mixture can be graded and tested.
