DEVELOPMENT OF THE ROAD METER: 1965 TO 1972

WHILE INCREASED USE, FAMILIARITY, AND CONFIDENCE IN THE ROAD METER HAVE OCCASIONED THE PRESENT WORKSHOP AND ITS EXCHANGE OF IDEAS, MANY USERS ARE DISTURBED BY ONE OR MORE PROBLEMS THAT HAVE ARISEN IN THE SEVEN YEARS SINCE THE AUTHOR DEVELOPED THE METER FOR THE PORTLAND CEMENT ASSOCIATION: DIFFERENCES IN MECHANICAL AND ELECTRICAL COMPONENTS THAT CONTROL ROAD METER OUTPUTS, DIFFERENCES IN ROAD METER OUTPUT WHEN A METER IS USED IN VARIOUS AUTOMOBILES, EFFECTS OF SEASONAL AND DIURNAL AMBIENT AIR TEMPERATURE ON THE METER AND THE PAVEMENT, DIFFERENCES IN ROAD METER OUTPUT CAUSED BY AMBIENT WIND VELOCITIES DURING TEST, AND THE NEED FOR A DEPENDABLE STANDARD FOR ROAD ROUGHNESS MEASUREMENTS THAT IS ESSENTIALLY TIME-STABLE AND IS AVAILABLE FOR CALIBRATING ALL ROAD METERS AND PROFILOMETERS. EACH OF THESE PROBLEMS IS DISCUSSED, AND APPROACHES TO A SOLUTION ARE PROPOSED.
