The pavement management system in its broadest sense means all activities necessary to preservation the pavement, including: planning, design, construction, maintenance and rehabilitation of the pavement. Maintenance considered an important activity to preservation the performance of the pavement which is itself divided into corrective maintenance and preventive maintenance and emergency maintenance. In this thesis it has been reviewing preventive maintenance and so are several considerations her characterize an effective cost and prolong the life of the pavement and provide convenience to users of the road. In this research it was conducted a visual inspection for several sectors, namely: (Madani – EL-Gadarif) and (EL-Gadarif - Kassala) and (Kassala - Hayia). And so as to reach the pavement condition index, which we can the decision making to execute preventive maintenance or corrective maintenance and rehabilitation of each sector, so that the pavement condition index over 70 is performed preventive maintenance treatments, as well as the type and severity of distress, we can choose the right treatment for deformation or the possibility of implementing the multiple treatments on a sector. Therefore, conduct routine inspection for the road network, and storage the data help us to put the schedules to the priorities conduct preventive maintenance, and preventive maintenance of the pavement is considered the cornerstone of preservation on the pavement, and longevity and delay of the need for corrective maintenance or rehabilitation because they are high cost and lead to the closure of the road and disrupt traffic and other reasons.
