Optimal maintenance works for Aborshada road in Libyain western region

Abstract EN

In this research, road pavement condition was investigated for Aborshada road in Gharian region to determine the optimal 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 visual technique “Pavement Condition Index (PCI)”, to survey the different distresses classified according to the PCI standards (ASTM standard in 2007 (D6433-07)) and to know the most commune distresses in the Aborshada road in order to provide assistance for decision maker in the pavement evaluation and optimum selection of repair method.

In this study, pavement condition evaluation techniques, scenario maintenance decision, and detail sheets for some distresses types in the Aborshada road were presented.

Counting on the pavement condition evaluation, the decision maker can find the effect of the maintenance works on the existing pavement condition.

Also, he can select the optimum alternative suitable for his fund.

This study reveals pavements actual performance and suggests the required research to deal with the pavement maintenance problem in Libya, especially in western region.

The study showed that the best maintenance alternative for Aborshada road was the case No.

4 (Potholes, Long.

& Trans.

Cracking and Alligator Crack Maintenance).

Also, it showed that, the most common pavement distresses on the Aborshada road were distresses No.

13, 10, 1, 3, 7, 6 according to ASTM-D6433-07 classification.
