Best Practices Maintenance for Aborshada Road in Libyain Western Region

Abstract

In this research, road pavement condition was investigated for Aborshada road in the Gharian region to determine the best maintenance works. Previously, Simple engineering judgment was the only procedure followed by Gharian Municipality engineers for pavement evaluation and maintenance prioritization. Aborshada road pavement surface condition was investigated by using the visual technique “ Pavement Condition Index (PCI)”, to survey the different distresses and classified according to the PCI standards (ASTM standard in 2007 (D6433-07)). Also, to know the most common distresses in the Aborshada road to provide assistance for decision-makers in the pavement evaluation and best selection of repair methods. In this study, pavement condition evaluation techniques, scenario maintenance decision, and detail sheets for some distresses types in the Aborshada road was presented. Based on the pavement condition evaluation, the decision-maker can find the effect of the maintenance works on the existing pavement condition. Also, can select the best alternative, which is suitable for the fund. This study reveals pavement's actual performance and suggests the required research, which deals with the pavement maintenance problem in Libya, especially in the western region. This study showed that the best maintenance alternative for Aborshada road was case No. 4 (Potholes, Long. & Trans. Cracking and Alligator Crack Maintenance). Also, this study showed that the most common pavement distresses on Aborshada road were distresses No. 13, 10, 1, 3, 7, 6 according to ASTM – D6433-07 classification.
