Pavement Integrity Index
Pavement Integrity Index (PII) is a combined index of the pavement faults in sealed road surfaces used widely in New Zealand. It is a ‘weighted sum’ of the pavement defects divided by total lane length. PII combines surface faults (CI) with rutting and shoving.
A High PII corresponds to high pavement integrity.
