ANALYSIS OF PAVEMENT PROFILE

METHODS FOR REDUCING ROAD PROFILOMETER RECORDS OF ELEVATION VERSUS DISTANCE TO A MORE COMPACT AND USEFUL FORM FOR HIGHWAY ENGINEERS ARE DISCUSSED. IT IS ASSUMED THAT VERTICAL IRREGULARITIES IN THE ROAD SURFACE HAVE BEEN TRANSFORMED TO AN ELECTRICAL VOLTAGE AND RECORDED ON MAGNETIC TAPE. SPECIFIC DIGITAL AND ANALOG METHODS ARE DESCRIBED FOR PROCESSING THESE SIGNALS AND REDUCING THE ROUGHNESS HEIGHTS AND WAVELENGTHS. DIGITAL AND ANALOG COMPUTER REQUIREMENTS ARE DEVELOPED FOR THE PROPOSED SIGNAL PROCESSING METHODS. RESULTS OBTAINED FROM COMPUTER PROCESSING OF BOTH IDEALIZED AND ACTUAL ROAD ROUGHNESS SIGNALS ARE PRESENTED AND CORRELATED WITH PREDICTED VALUES. /AUTHOR/
