The development aspects of three pavement performance indicators are presented. The prediction curves were developed for North Dakota using the most innovative methods available. The methodology adapted for use in the North Dakota pavement management system (NDPMS) is unique because three performance indicators are used in the system and the performance techniques were also used in seven city and county NDPMS installations. The three performance indicators developed were an overall distress index, a structural index, and a roughness index. NDPMS incorporates the three indexes in the performance prediction module of the analytical software that was developed. Pavement prediction curves were developed for each index. The final curves provide a reasonable method of predicting pavement performance in North Dakota. The development process provided many technological challenges that were channelled into the curve designs. (A)
