Selection of Pavement Types Based on Traffic Load and Life Cycle Cost Analysis

Traffic volume is generally one of the main factors determining pavement type. In the 2017 Indonesian Road Pavement Design Manual, planners are given several pavement-type options based on traffic volume and design life. In selecting the appropriate pavement type, both parameters cannot provide comprehensive guidance and could produce pavement structures that last under the predicted service life. In this study, an analysis was carried out to see if a recommendation can be given on selecting pavement type based on life cycle cost and traffic load analysis. This study used the Tepus–Jerukwudel road segment in the Southern part of Java Island as a case study. Two types of pavements, jointed plain concrete pavement and flexible pavement with asphaltic concrete or hot-rolled sheet as a surface layer were selected based on the 10 variations of predicted traffic loads. A detailed calculation of the road handling cost for each pavement type is carried out for life cycle cost analysis. The results showed that the types of road pavement recommended can be varies depending on its life cycle cost and traffic loads. One needs to analyze thoroughly based on the predicted traffic load and life cycle cost to ensure the proper type of pavement structure over its service life.
