Comparison analysis between plan and actual remaining service life of road pavement using Weight in Motion (WIM) data

Abstract

Transportation mobility is increasing every year and road infrastructure experiences increased loads. If the traffic load exceeds the planned load, premature damage can occur immediately and need more resources to maintain the damage. Therefore, Weigh in Motion (WIM)is needed to analyze the actual vehicle load on road infrastructure. The purpose of this study is to identify the Remaining Service Life and direct its maintenance patterns. By using WIM, the value of Remaining Service Life can be estimated. This paper presents the analysis result of the Weight in Motion data at Serang Barat Toll Gate in Indonesia and the impact on the Remaining Service Life. The axle loads were converted to represent single-axle loads based on 4th power formula by MDP 2017. The analysis showed that the CESA value obtained by using WIM data increased by 60.91% compared to the planned load and would cause a decrease in Remaining Service Life from the 20-year plan period to 16.82 years.
