Mechanical Shaker Efficiency

Over agitation and improper testing techniques for aggregate can lead to degradation of aggregate samples and improper test results.  To many technicians disbelief, ASTM C136 and AASHTO T27 do not specify how long a mechanical shaker’s timer should be set in order to accomplish proper agitation.  In order to understand the proper use of mechanical shakers, we must first explain the reasons for using this equipment.
