ASPHALT RATE OF SPREAD MEASUREMENT DEVICE

THIS NEW DEVICE, BASED ON A DESIGN BY MR. W.L. RUSSELL OF THE ROAD RESEARCH LABORATORY, CONSISTS OF A SHALLOW METAL TRAY, SECURED BY FOUR SHORT LENGTHS OF CHAIN TERMINATING IN A RING WHICH MAY BE PLACED OVER THE HOOK OF A SPECIAL SPRING BALANCE. THE BALANCE IS CALIBRATED TO GIVE THE COVERAGE IN SQ. YDS/TON OF THE ASPHALT BEING LAID. THE TRAY IS PLACED IN THE PATH OF THE ASPHALT SPREADER AND AFTER THE LATTER HAS PASSED OVER, IS CONNECTED TO THE BALANCE AND THE COVERAGE READ OFF ON THE SCALE. THE DEVICE ENSURES THE SPECIFIED RATE OF ASPHALT IS BEING LAID, AND NOT A LIGHTER RATE WHICH MIGHT RESULT IN AN INADEQUATE SKID-RESISTANT SURFACE FOR HIGH- SPEED VEHICLES.
