Bandar Udara Internasional I Gusti Ngurah Rai Bali yang dikelola oleh PT Angkasa Pura I terletak di Provinsi Bali. Seiring meningkatnya operasional penerbangan, pada area landas hubung (taxiway) ditemukan kerusakan pada perkerasan lentur seperti penurunan permukaan pada jalur roda pesawat dan tambalan (patching). Kerusakan ini dapat mengganggu kenyamanan dan keselamatan penerbangan. Evaluasi kerusakan menggunakan metode Pavement Condition Index (PCI) dan Surface Distress Index (SDI) bertujuan untuk menganalisis jenis dan tingkat kerusakan perkerasan pada taxiway NP 7 dan N7 sehingga dapat ditentukan pemeliharaan yang tepat dengan jenis kerusakan yang terjadi.
Penelitian evaluasi kondisi perkerasan ini menggunakan dua metode yaitu PCI dan SDI. Pengumpulan data dilakukan dengan cara survei lokasi pada taxiway NP 7 dan N7. Metode SDI mempertimbangkan empat jenis kerusakan utama, sementara metode PCI mencakup lima belas jenis kerusakan. Setelah diperoleh nilai kondisi perkerasan dari masing-masing metode, dilakukan analisis perbandingan untuk mengevaluasi hasil penilaian yang dihasilkan oleh kedua pendekatan tersebut.
Hasil analisis menggunakan metode PCI didapatkan bahwa nilai rata – rata PCI adalah 71 dengan kategori sangat baik. Namun pada STA 0+200 – 0+250 didapat nilai PCI sebesar 32 dan pada STA 0+400 – 0+450 didapat nilai sebesar 27 yang termasuk dalam kategori buruk. Sedangkan analisis kerusakan metode SDI didapatkan nilai rata – rata sebesar 9 termasuk dalam kategori baik. Sehingga dari perhitungan kedua metode tersebut perlu dilakukan perbaikan yang tepat berupa
patching dan overlay (STA 0-300 – 0+400).

EVALUATION OF FLEXIBLE PAVEMENT CONDITION ON TAXIWAY NP 7
AND N7 USING THE PAVEMENT CONDITION INDEX (PCI) AND SURFACE
DISTRESS INDEX (SDI) METHODS AT I GUSTI NGURAH RAI
INTERNATIONAL AIRPORT BALI

I Gusti Ngurah Rai International Airport in Bali, managed by PT Angkasa Pura I, is located in the Province of Bali. With the increasing intensity of flight operations, several types of damage have been identified on the flexible pavement in the taxiway area, such as surface depressions along aircraft wheel paths and patching. This damage has the potential to compromise flight safety and comfort. The evaluation of pavement distress using the Pavement Condition Index (PCI) and Surface Distress Index (SDI) methods aims to analyze the types and severity of pavement damage on taxiways NP 7 and N7, in order to determine appropriate maintenance measures based on the observed distress.
This pavement condition evaluation study employs two methods PCI and SDI. Data collection was conducted through field surveys on taxiways NP 7 and N7. The SDI method considers four primary types of distress, while the PCI method
encompasses fifteen different types. Once the pavement condition ratings were obtained from each method, a comparative analysis was carried out to evaluate the assessment results generated by both approaches.
Based on the analysis using the PCI method, the average PCI value was 71, which falls under the "very good" category. However, at station STA 0+200 – 0+250, a PCI value of 32 was recorded, and at STA 0+400 – 0+450, a value of 27 was found—both categorized as "poor." On the other hand, the SDI method yielded an average score of 9, which is considered "good." Therefore, based on the results of both methods, appropriate repairs such as patching and overlay are necessary, particularly in the area between STA 0+300 and STA 0+400.
