Analisis Penyebab Kerusakan Jalan Serta Desain Ulang Tebal Perkerasan Kaku Dengan Menggunakan Metode Manual Desain Perkerasan Jalan (Studi Kasus : Jalan Jenderal Sudirman, Desa Api-Api, Kec. Bandar Laksamana)
Pavement layer serves to receive and spread the burden of traffic without causing significant damage, where the pavement must have quality and thickness that can reduce damage due to vehicle loads. At present, the pavement conditions of Jalan Jendral Sudirman, precisely in Api-Api Village, Bandar Laksamana Subdistrict have been damaged, so it is necessary to evaluate the existing pavement conditions and to re-design the rigid pavement thickness to replace the existing flexible pavement thickness so that it can serve heavy traffic loads. This research aims to analyze the causes of pavement damage, identify the type and extent of existing pavement damage and redesign the thickness of the rigid pavement. The method to redesign the pavement thickness is using the Manual Desain Perkerasan Revisi September 2017, while to identify the type and level of pavement damage using the Pavement Condition Index (PCI) method. The results of this research indicate that the pavement damage that occurs on the sections of the fires is caused by the overload of vehicles (MST> 8 tons) which on the road is a collector road that can only be traversed by a maximum axle load (MST) of 8 tons. The level of damage that occurs is dominated by hole damage, longitudinal/transverse cracks and crocodile cracks. After analyzing the calculations using the PCI method, the PCI value obtained for bad conditions at STA 500-600 is 33.33 and for good conditions at STA 600-700 is 79. Based on the CBR value the field obtained by aggregate foundation A class thickness is 125 mm and 200 mm thick rigid pavement with K-300 kg / cm² concrete quality.
