The proposed methodology validated the micro-surfacing treatment as a valuable assessment system that can be successfully applied with or without other pavement maintenance treatments. Results demonstrate a representative service life over 4.5 years for the micro-surfacing treatment with a critical PQI value of 80. Finally, the service life of the micro-surfacing treatment was determined using the new PQI model. A new PQI model was developed using the optimum predicted long-term performance with the application of the grey rational degree theory. Grey models of different types of indicators are then established for predicting long-term performance. Firstly, over 5,375,000 data points from the Guangdong Province are collected and processed using the Pauta criterion and short-term trends of selected performance indicators including pavement surface condition index (PCI), riding quality index (RQI), rut depth index (RDI), and skid resistance index (SRI) are analysed.
