THE DANA AUTOMATIC RECORDING ROUGHOMETER FOR MEASURING HIGHWAY ROUGHNESS

THE INSTRUMENT'S ESSENTIAL FEATURES ARE: (1) THE RECORD PAPER RUNS FIVE INCHES PER MILE WITH A FASTER SPEED OF THREE INCHES PER ONE HUNDRED FEET AVAILABLE FOR SPECIAL ROUGHNESS STUDY; (2) A PENCIL OPERATED THROUGH A PANTOGRAPH SYSTEM CONNECTED TO A FRONT WHEEL GIVES A CONTINUOUS VISIBLE PICTURE OF THE ROUGHNESS OF THE ROAD SURFACE; (3) AN AUTOMATIC STAMPING DEVICE PRINTS THE MILEAGE ON THE RECORD EVERY HALF MILE OF MORE OFTEN AS REQUIRED; (4) THE SAME STAMPING DEVICE PRINTS THE INTEGRATED ROUGHNESS ALONG THE MILEAGE. A BRIEF HISTORY OF THE DETERMINATION OF THE RELATIVE ROUGHNESS OF ROAD SURFACES IS PRESENTED BY MR. TELLER. MR. BRYANT REPORTS ON EXPERIENCE IN MARYLAND USING A BPR TYPE ROUGHOMETER. /AUTHOR/
