Visual Assessment of Flexible Pavement (PCR) on the Road Network of Gharyan CityCase Study: Al-Thawra Street in the City Center

Roads are one of the most important means of transportation in most countries of the world. So that road networks have become a measure of the development of countries in terms of economic, industrial and service due to the many benefits they provide from facilitating the movement of people and the transport of goods and raw materials. The Gharyan city is one of the largest cities in the Western Mountains, which is the commercial and administrative center of the region and is the largest in terms of residential density among these cities. The city has a large road network extending to hundreds of kilometers that was established in the seventies and eighties of the last century linked to the cities of the mountain. It is also the link between the north and south cities of Libya, and the city's road network suffers from low levels of traffic safety. This study aims to identify paving problems, match design standards with local standards, and determine the necessary maintenance process. To assess the condition of the existing pavement, the road was divided into six sectors of the road study in the city network, then the damage was limited and examined in each sector, the amount of damage was calculated and its severity estimated, and the visual inspection method was used to assess the condition of the pavement. The summary of the Pavement Condition Rating (PCR) condition evaluation was ranged between Fair to Poor and to Very Poor (57.8 to 39.15) and the worst sector on the road was (G-H) and the best-rated sector was (E-F).
