A PROCEDURE TO MEASURE THE EFFICIENCY OF TOWED OR SELF- PROPELLED ROAD MIXERS PRODUCING CEMENT OR LIME TREATED SUB BASES AND BASES IS DESCRIBED. METHODS TO MEASURE THE RATE OF SPREADING AND DEPTH OF MIXING ARE ALSO DESCRIBED. TWO BRANDS OF LIME SPREADERS WERE INVESTIGATED FOR UNIFORMITY OF SPREAD RATE OVER THE AREA TO BE TREATED. THREE MAKES OF ROTARY MIXERS AND TWO MAKES OF PUGMILL MIXERS WERE INVESTIGATED TO MEASURE UNIFORMITY OF MIXING AND DISTRIBUTION OF LIME OR CEMENT IN THE ROAD-MIXED PRODUCT. /AUTHOR/
