The revolving of the drum shall be continuous until the concrete is completely emptied from the drum.

E. When concrete is being placed for concrete structures, all wash water shall be emptied from the mixer before any portion of the succeeding load is placed therein. For all other work, the mixer shall be empty or may carry 10 gallons of water in the drum. Adequate control of ready-mixed concrete in the drum will sometimes require that additional water be added and mixed into the batch at the point of discharge. Water so added shall be mixed 3 minutes.

Water shall not be added to the load during transit.

F. The total elapsed time between the addition of water at the batch plant and discharging the completed mix shall not exceed 90 minutes. Under conditions contributing to quick setting, the total elapse time permitted may be reduced by the Engineer.
