EVALUATION OF THE NEW VIRGINIA DEPARTMENT OF HIGHWAYS AND TRANSPORTATION SKID TESTING TRAILER

In an effort to evaluate a new skid trailer and to determine how the survey skid testing program should be conducted in light of findings, a study was made of the trailer's testing precision; operational error (defined as unexplained day-to-day variation); the speed-skid number relationships obtained for some customary surface types used in Virginia; and the relationship to the skid trailer and stopping distance car. Tests were conducted in 2 phases on 15 sites. Each site was tested at multiple speeds, with five tests being run at each test speed. Data obtained in both phases are tabulated. Recommendations (based on the results) are made with regard to: the speed for survey testing (40 mph); correction to skid numbers; control site testing; reporting survey skid test data; annual verification of relationships between testing devices; testing rate; and sites with borderline skid resistance.
