The road is constructed according to the engineering measurements and technical specifications required to obtain a structure capable of performing, its function perfectly, during the design life of the road.

However, as a result of use and aging, many changes occur in the origin of the road and in the properties of the road materials, and thus the pavement is exposed to structural and functional damage.

What is meant by structural damage is the collapse of the entire paved structure or part of its components to the extent that makes this structure unable to support the loads falling on its surface.

As for the functional damage, it is related to the serviceability of the paved structure and its primary suitability for use and has nothing to do with the ability of this structure to support the loads placed on it.

Functional damage is mainly related to the degree of roughness of the paving surface.

To determine this damage, it is necessary to follow methods to evaluate the damage, followed by the required maintenance.

This study was conducted on the Zuwara Marine Road as a case study, as it is a vital road that serves the port and the commercial and residential area, in addition to the presence of major structural damage to it.

The methodology was to collect information through a field visit, conduct a traffic survey during morning and evening peak hours to determine the volume of traffic flow, take samples of natural soil and the granular base layer, and conduct a California Load Ratio (CBR) test.

Then, the PCR method was used to evaluate the pavement condition, which showed that the road was worn out and needed to be repaired (renewal process).

The road was also redesigned geometrically and structurally according to the information obtained.

The study concluded with a number of conclusions and recommendations, that we hope will be taken into consideration by specialists.
