1 Z-Score Summary - Asphalt Proficiency ing Program (73) Z-SCORES SUMMARY Asphalt May/June 2017 (73) The proficiency program was conducted in May/June 2017 with participants throughout Australia. AS 2891 test methods were preferred but other methods were allowed in this program. This summary provides the z-scores for the following tests. Particle size distribution Bitumen Content Maximum Density Bulk Density A z-score summary is provided to allow participants to gauge performance and address outliers as early as possible. It is recommended that any remedial action be undertaken cautiously until the final report for the program has been consulted. The z-scores shown are unlikely to change significantly. Small changes however may become necessary during preparation of the final report. The final report provides other information, apart from z-scores, that may be used to access performance and interpret the significance of outliers. Participants may forward the summary report to NATA as an indication of a participant s general performance. All participants need to assess their overall performance once the final report has been issued. The final report once issued supersedes the z-score summary.
