AS 2891.14.15:2018 pdf download.Methods of sampling and testing asphalt Method 14.15: Mean, standard deviation coefficient of

variation and characteristic values.

NOTE: The acceptance constant (k) is usually detailed in the specification. However, when this value is not specilied, the commonly used values are shown in Table Al of Appendix A.

Alternatively, the value may be derived from the tables listed in Main Roads Western Australia Engineering Road Note 8.

5 TEST REPORT

The following shall be reported, as required:

(a) The characteristic values of the test results and the acceptance constant used.

(b) The mean value of the test results.

(c) The standard deviation of the test results.

(d) The number of individual values used.

(e) Any individual results excluded from the calculations and the reason for the rejection.

(f) Reference to this Standard, AS 2891.14.15.

Additional information, as required by the test methods used to determine individual values, shall also be reported.
