Big Bill Mixer

Listing ID #3326428

Big Bill Mixer is a heavy-duty orbital shaker for use in determining maximum specific gravity and density of bituminous paving mixtures. Studies have shown that the use of an orbital shaker to agitate the sample within the flask while drawing a vacuum on the sample results in more accurate and unifrom test results. The defined orbit(19 mm), as well as the digitally controlled speed of the shaker allows each lab to perform the test according to the defined procedure and provides reproducibility of the test between individual labs.

Big Bill Mixer, shown by several studies, prevents densification of the bituminous material in the center of the flask. Vibrating shakers can actually promote the densification of the material during the test. The densification can inhibit the extraction of entrapped air within the bituminous mixture.

It can accommodate several samples at the same time. Four 4 liter glass flasks and three metal pycnometers.
