The objective of this paper is to provide succinct information about the use of noncontact transducer devices connected to the high-speed profilometer for the purpose of measuring the road profile. The standard Surface Dynamics (SD) profilometer has two tracking wheels to measure the height between the frame of the car and the pavement, and that distance is used to obtain the road profile. Furthermore, extremely rough sections tend to damage the potentiometer, which is connected to the tracking wheels. The trailing arm, to which the tracking wheels are connected, is held in contact with the road by a 300-lb force exerted through a torsion bar. The standard profilometer functions at 20 mph, because at this speed the torsion bar minimizes the bouncing of the wheels. Speeds greater than 20 mph produce bouncing in the wheels, thereby deforming the profile. The use of noncontact probes in the profilometer gives the capability of increasing the profilometer speed during the profiling process, and damage to the potentiometers is avoided when rough sections are profiled. Profile data obtained with two noncontact devices are compared with data obtained on the same road with the standard profilometer. A comparison between noncontact devices at two different speeds (35 and 50 mph) is also made. General regression equations for predicting root-mean-square vertical acceleration (RMSVA) and serviceability index (SI) are presented.
