Managing paved networks such as roads, parking lots, pedestrians’ sidewalks, walkways and yards is an important issue in Al-Zaytoonah University of Jordan as well in other universities and organizations, which includes large paved areas utilized as parking spaces and students’ bus terminals. A PMMS can be a useful tool for evaluation and prioritization of M&R projects, determination of funding requirements and optimum allocations. The development of Pavement Management System (PMS) products has supported systematic and economic management of pavements [1, 2]. The maintenance at early stages of pavement deterioration proved to produce large savings before the start of the costly sharp decline in pavement condition as clearly illustrated in Fig. 1.

2. Literature Review

Many researchers have studied the performance of paved networks and the probable factors that caused distresses. It was concluded that trucks with axle loads exceeding the legal limit, poor designed drainage systems and lack of quality control are the most probable causes for deterioration of road network in Jordan [3].

The relationship between roads pavements failures, engineering indices and underlying geology of sub-grade layers were studied [4]. It was noted that roads with high failure rates are supported by poor sub-grades, whereas highways with low failure rates are supported by weathered sub-grades. The researchers also emphasized the provision of drainage systems to reduce rates of road failures.
