The Effect of Overdimension Overload (ODOL) Vehicles on Road Technical Life (Case Study: Enrekang Regency National Road Segment)

Abstract

The zero over-dimension overload (ODOL) policy must be achieved and pursued by all parties, Government, Industry, Entrepreneurs and society. The realization is still a problem today. In current developments, the business world is still having difficulty achieving Zero ODOL status by 2023. In Enrekang Regency, the issue of Over Dimension Over Load violations in goods transportation has become a significant problem, prompting research to analyze the technical condition of roads affected by these vehicles. Vehicle weight data was obtained from a direct survey at Motor Vehicle Weighing Implementation Unit Datae Sidrap Regency by aligning data on the volume of vehicles crossing the National Road in Enrekang Regency which is divided into 6 (six) segments. The analysis results show that the Cumulative Equivalent Standard Axle Load (CESAL) value for pavement with a design life of 10 years and bearing the final load under normal conditions is 1761904.7231 ESAL. If calculated using the overload condition in segment 1 with a CESAL value of 1999990.7130 ESAL, then the technical life of the road can only last for 8.81 years or there is a decrease in the life of the road pavement by 1.19 years. Meanwhile, if calculated using excessive load conditions in other segments (2, 3, 4, 5 and 6) with a CESAL value of 3199438.6973 ESAL, then the pavement life can only last for 5.51 years or there is a decrease in the pavement life of 4. 49 years old. So a treatment program is needed in the form of periodic maintenance (rehabilitation) or road pavement reconstruction. Apart from that, the addition of axles for vehicles that have not yet reached the normal Vehicle Damage Factor (VDF) value is very influential in reducing the level of road damage.
