Test Methods and Specifications

Where a statistical approach to product acceptance is used, the characteristic value for the lot is determined by analysing multiple random test results from the lot.

Characteristic values may be specified for properties such as geotextile strength, compaction of pavement and earthworks layers and the voids ratio of asphalt.

This test method provides a means for calculating a characteristic value determined by the analysis of multiple individual test results, tested using the same methods, using a statistical process.

This test method can also be downloaded as a Word document.
