Problem of Study: EVALUATION PAVEMENT DISTRESSES USING PAVEMENT CONDITION INDEX - Diponegoro University | Institutional Repository (UNDIP-IR)

4 expense exceeds the cost of construction itself because it was disrupting traffic generated by the delay in the establishment of these roads. Preventive maintenance is an essential tool for extending the life of a pavement. Used early in a pavements life, preventive maintenance corrects small problems before they become big problems, saves money, reduces delays and improves safety and ride ability. Therefore profession engineer maintained until the roads are always safety ways and the movement for passengers or goods are a comfortable and economical at all times Bashir, 2006. Not all pavement structures are constructed alike, nor do all pavement structures perform identically. Therefore, it is necessary to monitor the maintenance requirements of each general type of pavement. By monitoring the performance of pavement sections of similar construction and usage, sufficient information can be developed to forecast maintenance requirements ADO, 1999.

1.3 Objective of Study:

The key element to surface evaluation management programs is to identify the different types of pavement distresses and determine their causes. Knowing what caused the pavement distress allows the appropriate maintenance treatment to be applied Lavin, 2003. Basic objective of this study is to 1. Investigate and evaluate the asphalt pavement defects by using pavement condition index PCI. 2. Estimate the maintenance options. 1-4 Location of Study: Libya is located in North Africa on the coast of the Mediterranean Sea. It is bordered on the east by Egypt; on the south by Sudan, Chad, and Niger; and on the west by Algeria and Tunisia see figure 1.1Federal Research Division, 2005. 5 Figure 1.1 Map of Libya FRD, 2005 The study road lies in the north east part of Libya in Koms city. It is called Mslata road, classified it is secondary road, this link district centers and villages. Figure 1.2 Roads network in Koms city Google earth
