effects of slurry filling and mill speed on the net power
Chapter Five
When temperatures are high, the operator might need to accelerate the ground speed of the microsurfacing machine and/or decrease the rate at which the materials are mixed in the pug mill. A common rule of thumb is to set a production rate that corresponds to a mix dwell time in the spreader box of 45 s or less (Wood 2007).
