the most costly option. This pavement needs thick overlay, and it does not need complete reconstruction.
5.2 RECOMMENDATION
In particular the following suggestions may be considered in future study: 1-
New technology developments have produced a methodology that can quickly inspect roads and streets by using automated inspection equipment .The
automated system has the ability to assess the condition of the pavement and use the resulting data to create and populate a database. This can be
conducted at the same cost or less than manual survey procedures and the surveys become safer and less labor intensive.
Therefore, it is recommended to consider using automated survey techniques to reduce labor needs and increase safety of any personnel in-house or
contractor that may conduct the surveys. 2-
Effective maintenance can extend a pavements life. Crack sealing and surface treatments can reduce in aging of asphalt pavement.
3- Axle-load of vehicles must be controlling the load for preserving the
Pavement condition. 4-
The superintendence of any tarmac way since the beginning of its implementation to find out defects and their causes and its maintenance
5- The provision of necessary equipment for maintenance work in order to raise
the level of efficiency of maintenance. 6-
Training of special teams for maintenance working under the supervision of engineers who have experience.
7- Attention of water drainage away from the road surface till does not lead to the
collapse of the pavement .Attention of water drainage away from the road surface till does not lead to the collapse of the pavement.
8- Make a study the current traffic volume, which is expected in the future.
9- Interest in the implementation of the specifications during construction.
10- Periodic inspection is necessary to provide current and useful evaluation data.
It is recommended that ratings be updated every year. All the roads must be continuously monitored to improve the future data.
