Title: THE EFFECTS OF PUGMILL STRUCTURE AND ASPHALT SPRAYING MECHANISM ON THE MIXING AND PROPERTIES OF THE MIXTURE
Accession Number: 00211421
Record Type: Component
Abstract: A NATIONAL EXPERIMENTAL STUDY IS BEING CONDUCTED BY THE BUREAU OF PUBLIC ROADS TO TRY TO SETTLE ON UNIFORMITY OF MIXING VOLUME AND MIXING TIME REQUIREMENTS IN CEMENT CONCRETE PAVING WORK. A BRIEF REVIEW IS PRESENTED OF THE FOLLOWING TYPES OF MIXERS: THE BATCH MIXER, CONTINUOUS MIXERS, IMPACT MIXERS AND ROTARY DRUM TYPE MIXERS. MORE AND BIGGER BATCHES PER HOUR, AFTER ALL OF THE LOST MOTION IN BATCHING IS ABSORBED, MEANS STRETCHING MIXER EFFICIENCY AND TRIMMING THE TOTAL DRY AND WET MIXING TIME. MIXING TIME IS THE ONLY RELIABLE MEASURE OF MIX CONTROL AVAILABLE. IF A METHOD IS NATIONALLY ESTABLISHED OF RATING EFFECTIVENESS OF MIXING, THE MIXING TIME REQUIREMENTS COULD BE ELIMINATED. REGARDLESS OF THE TYPE OF MIXER USED, THE MIXING ITSELF IS DONE IN A TWIN-SHAFT PUG MILL.
