“…The PDR results show that overload vehicles can reduce almost half of the flexible pavement life span (4-5 years in this study). Previous studies in Ecuador [21] have nearly the same results with the present study, where there is a significant reduction in the life span of pavement up to 40%. Another study in Indonesia also shows a substantial reduction (60%-80%) in the level of serviceability of pavement due to overload vehicles [22].…”

Overloaded vehicles is one of the main problems that cause premature failure in road infrastructure. This paper presents an analysis of overloaded vehicles' effect on flexible pavement based on historical weigh-in-motion data. This article highlights the potential use of weigh-in-motion (WIM) data in pavement design by addressing the overload, the percentage of overloading, and axle load distribution. The percentage of overloaded vehicles can reach more than 80% of the total number of trucks and maybe one of the substantial factors that reduce pavement's service life. The actual traffic load is presented in the form of distribution for each type of axle load (axle load spectra) and the Vehicle Damage Factor (VDF) for each truck type. The effect of overload on the flexible pavement's design life is estimated by using the Cumulative ESAL comparison and Pavement Damage Ratio. Both analyses show that overload vehicles significantly decrease the pavement design life up to nearly half of the pavement life.

“…Perencanaan konstruksi jalan yang kurang tepat dapat mengakibatkan kerusakan struktur lapis perkerasannya, faktor yang menyebabkan kerusakan pada lapis perkerasan diakibatkan karena bahan material yang kurang baik, padatnya lalu lintas serta pelanggaran pada pemilik kendaraan berat yang tidak sesuai dengan bobot kendaraan maksimum sehingga beban yang di terima jalan berlebihan [7] [8]. Salah satu kerusakan yang terjadi pada lapis perkerasan ialah retak serta berlubangnya jalan karana terkelupasnya susunan lapis pekerasan [9][10] [11], maka dari itu perlu dilakukan perbaikan lapis pekerasan sehingga dapat melancarkan aktifitas mobilitas masyarakat.…”

Road pavement damage is an important thing to pay attention to. Improper planning, increasing traffic volume loads to lack of care and maintenance are factors that cause road damage. Road damage has an impact on the safety of road users. On the Joyoboyo East Kediri road, there are several roads that suffered significant damage. This study aims to design the repair of damage to the East Kediri Joyoboyo road. Repairs are carried out by adding a layer of pavement to the potholes. The component analysis method is used to determine the required pavement thickness. With the component analysis method, the design equivalent cross section will be calculated based on traffic data, as well as soil bearing capacity, regional factors and surface index. So that the pavement thickness index is obtained to determine the required pavement thickness. The result of this research is that the cross equivalent is 116.730, the regional factor value is 0.5 and the Surface Finish Index is 1.5. From the results of these calculations, Nomogram 5 was used and the Pavement Thickness Index value was 5.2. So that the required overlay thickness is 5 cm. These results can be used as a reference in repairing pavement damage on the Joyoboyo Timur Kediri road, so that it can support the safety of road users and facilitate transportation.

“…Many researchers reported that the structural performance of pavement is significantly affected by the movement of heavy truck traffic resulting in the reduction of pavement life [ 107 , 108 ]. Furthermore, channelization of connected and autonomous truck (CAT) system increases loading repetition on the narrower width of the lane compared to human-driven vehicles [ 102 ].…”
