Software and Manual for Recording and Analyzing RDD Rolling Sensors (CD-ROM)

As part of the development of the Total Pavement Acceptance Device (TPAD), the Center for Transportation Research (CTR) created post-processing software for calculating the dynamic deflections of the pavement from the output of the rolling dynamic deflectometer (RDD) rolling sensors. To analyze the data, the software performs these steps: (1) load raw voltage signals of the RDD rolling sensors, (2) apply the composite infinite impulse response and finite impulse response filters, (3) apply field or lab determined calibration factors to calculate peak-to-peak deflections over a time interval determined by a testing speed, (4) normalize the dynamic deflections to a force level selected by the data processor with dynamic force-time data (normally a peak-to-peak force level of 10 kips), (5) average the converted rolling sensor deflections over a selected distance, and (6) apply a moving average.
