Long-term pavement performance (LTPP) studies in New Zealand: lessons, the challenges and the way ahead

New Zealand embarked on a Long-Term Pavement Performance (LTPP) programme with the establishment of 63 LTPP sites on the State Highway network during 2000. In 2003, this programme was expanded to include more than 21 local road controlling agencies by instituting a further 82 LTPP sites. This paper reviews the data collection methodology, relative to the original study objectives, assumptions and specifications. The statistical characteristics recorded for the design matrix factors for the state highway LTPP sections has indicated that the full range of expected values on the New Zealand network are being monitored. Furthermore, it is concluded that an appropriate level of data collection accuracy has been adopted for the New Zealand programme. At this early stage, the LTPP New Zealand programme has been successful in achieving its goals and objectives. On the other hand, a review of the data has highlighted areas where further research is required and proceeding. (a) For the covering entry of this conference, please see ITRD abstract no. E212095.
