Abstract

Economic growth that occurred in Indonesia requires adequate infrastructure. A large number of infrastructure found in Indonesia is not accompanied by the compliance level of infrastructure users, the number of violations that occur causes a decrease in the life of a road. Overloading does not only causes road damage but also impacts the lack of road safety. Therefore, research and analysis are carried out to find out how much influence is given by the overload on a road, in this case, the age of the plan. The method used to find out how big the impact of a normal charge is with remaining life, which is to compare the age of a normal load plan with overload. By this method it is necessary to know the Vehicle Damage Factor (VDF) which will later be used to find the cumulative ESAL of each vehicle condition, then with the cumulative ESAL that occurs can know the remaining life of a road. From the conducted analysis result, it was found that each vehicle had an increase in vehicle damage factor (VDF), as well as the cumulative ESAL that was previously planned to receive cumulative ESAL in the amount of 20.602.172 with the cumulative overloading of ESAL, received to 284.426.068, due to the charge causing a decrease in remaining life is 4 years 9 months or decreased by 24%.

Abstract

The road network is a land transportation infrastructure that plays an important role in the transportation sector, especially for the balance of the distribution of goods and services, both from other regions. In this study, an analysis was conducted to find out how the influence of heavy vehicle volume increase on the service life of the road, while the method used was Bina Marga, the study was conducted by taking a case study on the Hera road section until Dili. This research is expected to find out how the service life of the road if the volume of heavy vehicles continues to increase. If the% of heavy vehicles increases, the thickness of the required surface layer will also be even greater. When% of vehicles or carrying heavy traffic loads are increased, the thickness of the existing layer cannot meet, because the calculation results with% of heavy vehicles increase by 10%, surface thickness 17.2 cm / This will cause the service life of the road to decrease because it is confirmed that the road will be damaged before the service period ends due to excessive load increase in heavy vehicles.
