Performance modelling has become a key element of a Pavement Management System (PMS). The Gauteng Province of South Africa has established 36 Long-term Pavement Performance (LTPP) sections which are monitored annually to improve and calibrate PMS performance models. This paper describes how the LTPP sections were set out, monitored, and how the collected data influenced the pavement performance models captured in the PMS. Initially the HDM-III pavement performance models were calibrated and captured in the PMS. Subsequently improved models have been proposed for inclusion in HDM-IV. These proposed models are evaluated on the LTPP data. It is also shown how the inclusion of the calibrated performance models has influenced PMS decisions. 1.
