| Abstract | ||
| Precedence setting techniques as used in the Pavement Maintenance Management Systems (PMMS) cover.a,wide spectrum of methods and approaches ranging from simple precedence lists based on engineering judgment to complex network optimization models. In this pap&, three precedence setting techniques are presented along with the results of their applications using data collected from the Egyptian road nehvrk. The first technique is a simple ranking one in which four ranking measures was used in the analysis: (i) lowest Life cycle cost; (ii) worst condition iirst; (iii) highest traffic and (iv) highest benefithost ratio. The second technique is a combined ranking technique based on relative weights assigned to the above mentioned four ranking measures. Finally, the third technique is a linear programming optimization model, which considers both time (current and future) and space (entire network). A comparison between the three techniques, in terms of network condirion over rime and in terms of budget deficit over time, is in the oaver. The results indicated a considerable difference in future network oerformance under the | ||
