CALIBRATION AND USE OF BPR ROUGHOMETER AT THE AASHO ROAD TEST

THE PRIMARY PROBLEM IN USING THE BUREAU OF PUBLIC ROADS ROUGHOMETER AT THE AASHO ROAD TEST HAS BEEN THE VARIABILITY OF THE INSTRUMENT. FREQUENT CALIBRATION HAS BEEN FOUND TO BE NECESSARY. USING THE ROAD TEST PROFILOMETER AS A STANDARD, A METHOD HAS BEEN DEVELOPED WHEREBY THE WHOLE DYNAMIC SYSTEM OF THE ROUGHOMETER CAN BE CALIBRATED. THIS PAPER DESCRIBES THE CALIBRATION TECHNIQUE FOR THE ROUGHOMETER AND ITS USE AT THE AASHO ROAD TEST, INCLUDING METHODS FOR MAKING PRESENT SERVICEABILITY DETERMINATIONS. /AUTHOR/
