Sultan Hasanuddin Airport Taxiway Rigid Pavement ACN and PCN Analysis with COMFAA 3.0 and ELMOD

Abstract

This research focuses on Sultan Hasanuddin Makassar International Airport, which had an average of 48,949 aircraft movements in 2019. The study utilizes COMFAA 3.0 and ELMOD software based on Heavy Weight Deflectometer (HWD) deflection bowl data. The aim of this study is to analyze the quality and load-bearing capacity of the rigid pavement structure in the taxiway area to support critical aircraft loads, specifically the B747-400ER, and to determine the Aircraft Classification Number (ACN) and Pavement Classification Number (PCN) using relevant software. The research results indicate that the rigid pavement construction in the taxiway area is capable of accommodating operating aircraft, with a 400 mm thick slab of rigid pavement and a 150 mm thick lean concrete layer. The ACN and PCN values obtained from the analysis using COMFAA 3.0 software are PCN 74 R/B/W/T with ACN 69.8, and using ELMOD software, PCN 103/R/B/W/T with ACN 70 based on the 10th percentile method of the total PCN value. In conclusion, the rigid pavement in the taxiway is capable of handling the full load of the B747-400ER aircraft as the critical aircraft, with PCN > ACN.
