Good road pavement is also expected to provide a sense of safety and comfort in driving, especially affect the smooth flow of traffic. One of the causes of road damage is the lack of maintenance costs which results in a decrease in the quality of implementation. The rapid growth of vehicles has an impact on traffic density, both on inner-city and outer-city roads, so that it is necessary to improve the quality and quantity of road infrastructure. The goal to be achieved in writing the results of this thesis is to find out what types and percentages of damage occurred Abdul Haris Nasution Road Section and maintenance handling and knowing the thickness of the pavement layer required Abdul Haris Nasution Road Section. Road damage is analyzed using the Indonesian Road Capacity Manual Method while flexible pavement thickness planning is adjusted to the Component Analysis Method with a design life of 20 years.
