FIELD TEST AND EVALUATION CENTER FOR EASTERN STATES ANALYSES OF 1975 DYNAMIC CORRELATION DATA

15 Skid Measurement systems from the Eastern States were evaluated and calibrated at the test center. Analyses of the dynamic correlation data for each system was submitted to each State in individual reports. This report attempts to summarize the findings from all State reports during the period April 7 through August 11, 1975. Analyses were performed, addressing two major issues: 1) The average skid number variation over the entire period (April to August); and 2) The short-term skid number variation (within correlation) relative to long term variation. The two factors examined related to long term variation and pad wear and temperature (both ambient and pavement temperature), using data from the first and second dynamic correlation data. The report also includes the results of an independent study concerned with the procedures used in the correlation program itself. Details of data collection, analyses and finding may be found in the appendix. Finally, the question of errors introduced as biases in computing the skid number (SN) from tractive force (F) and skid trailer dynamic load (W) is examined. /FHWA/
