This study evaluates the condition of the pavement on the Abu Daraa, Al-Guba road, a 4.6 km rural road in northeastern Libya. This road endures heavy loads from the Egyptian border, such as marble and building materials. The evaluation was conducted visually using the PAVER system, which assesses pavement condition and detects damage. Also, MICRO PAVER software analyzed the data to determine the road's pavement condition index (PCI), identifying the most common surface defects. The inspection revealed that the predominant defects are mesh cracks, crocodile cracks, subsidence, longitudinal and transverse cracks, and potholes. The average PCI of the road sections was 57, indicating poor condition and the need for urgent maintenance. The recommended maintenance involves scraping the damaged asphalt layer and applying a new cladding layer to extend the road's lifespan.
