APRB would like to acknowledge the assistance from AfPA and their members who provided field data.
- a procedure to remove uncharacteristic values from the dataset used to calculate the density bias
- limitations on the pavement temperature while carrying out PQI testing
- possible replacement of the cloverleaf pattern with repeated testing at a single position, pending outcomes from further studies.
It is also recommended that a controlled study be undertaken to assess the proposed updates to test method Q326 and the relative performance of the PQI device against the NDG.
