• Abstract:
  The purpose of this investigation was to determine the variability of the Virginia Department of Transportation's (VDOT) indirect tensile stripping test. Five contractor labs and eight VDOT labs participated in the study. Each lab performed three replicate tests on each of two mixes, one containing hydrated lime and one containing chemical antistripping additive. The standard deviation was 3.5 percent for within-lab results and 6.1 percent for between-lab results. Lack of significant correlations between strength and voids total mix indicated that a strength correction procedure for voids is not necessary. Examination of the VDOT specification indicates that contractors need to maintain the average TSR of the alternative mix containing chemical additive at least two standard deviations above the minimum value to ensure that single tests do not fail.
