Abstract : COMMERCIALLY AVAILABLE, TOWED-TYPE CONSTRUCTION MIXERS WERE MODIFIED AS SNOW MIXERS FOR THE NAVY'S COLD-PROCESSING SNOW-COMPACTION TECHNIQUES. TWO SIZES OF SNOW MIXERS, ALONG WITH OTHER SPECIAL EQUIPMENT, MENT, WERE NECESSARY TO PRODUCE GOO-QUALITY COMPACTED SNOW. ONE SIZE, A MODEL 24 SNOW MIXER, HAD A 24-INCH-DIAMETER ROTOR, A MAXIMUM PERIPHERAL SPEED OF 4960 FEET PER MINUTE. THE OTHER SIZE, A MODEL 42 SNOW MIXER, HAD A 42-INCH-DIAMETER ROTOR, A MAXIMUM ROTOR SPEED OF 515 REVOLUTIONS PER MINUTE, AND A MAXIMUM PERIPHERAL SPEED OF 5665 FEET PER MINUTE. BOTH MODELS SATISFACTORILY MIXED AND BLENDED SNOW FOR DEPTH-PRCESSED, COMPACTED-SNOW MATS. THEY WERE ALSO USEFUL FOR PROCESSING NEW DEEP SNOWFALL AND HEAVY DRIFT ON COMPACTED MATS FOR MAINTAINING THE COMPACTED SURFACE. THE MODEL 24 MIXER CAN CONSTRUCT A MAT UP TO 16 INCHES THICK; THE MODEL 42 MIXER CAN CONSTRUCT A MAT UP TO 28 IN THICK. TMIXERS ARE EFFECTIVE AT SPEEDS OF 150 FEET PER MINUTE AND A SINGLE UNIT CAN COVER 1-1/4 ACRES PER HOUR UNDER FAVORABLE CONDITIONS
