Abstract

Sirkuit Gelora Bung Tomo (GBT) Surabaya merupakan salah satu fasilitas olahraga otomotif yang memiliki potensi untuk dikembangkan menjadi sirkuit bertaraf internasional. Namun, kondisi geometrik lintasan eksisting belum memenuhi persyaratan teknis yang ditetapkan oleh Fédération Internationale de l'Automobile (FIA) Grade 1 sehingga diperlukan modifikasi geometrik untuk meningkatkan aspek keselamatan, kenyamanan, dan performa lintasan sesuai standar yang berlaku. Penelitian ini bertujuan untuk merencanakan modifikasi geometrik Sirkuit Gelora Bung Tomo Surabaya berdasarkan standar FIA Grade 1. Perencanaan meliputi modifikasi konfigurasi lintasan yang mencakup perencanaan geometrik horizontal berupa penentuan radius tikungan, lengkung peralihan, dan superelevasi, serta perencanaan geometrik vertikal berupa alinyemen vertikal. Selain itu, dilakukan perencanaan struktur perkerasan lentur berdasarkan kondisi tanah dasar menggunakan nilai California Bearing Ratio (CBR) sebagai dasar perencanaan struktur perkerasan. Metode penelitian dilakukan melalui pengumpulan data sekunder berupa layout eksisting, data topografi, data tanah, serta studi literatur terhadap standar FIA Grade 1 dan peraturan teknis yang berkaitan dengan perencanaan geometrik dan struktur perkerasan. Tahapan penelitian meliputi analisis geometrik lintasan, perencanaan alinyemen horizontal dan vertikal, perhitungan radius tikungan, lengkung peralihan, superelevasi, serta perencanaan struktur perkerasan berdasarkan karakteristik tanah dasar. Hasil penelitian menunjukkan bahwa modifikasi geometrik menghasilkan rancangan Sirkuit Gelora Bung Tomo dengan panjang lintasan ±4,359 km dan 11 tikungan yang memenuhi kriteria dasar FIA Grade 1 melalui penyesuaian konfigurasi lintasan, radius tikungan, lengkung peralihan, superelevasi, dan alinyemen vertikal sehingga meningkatkan aspek keselamatan, kenyamanan, serta kualitas lintasan balap. Berdasarkan hasil analisis nilai California Bearing Ratio (CBR) tanah dasar, diperoleh desain struktur perkerasan lentur yang dihitung menggunakan metode perkerasan Laston, dengan lapis permukaan direncanakan menggunakan Stone Mastic Asphalt (SMA) sebagai material surface course untuk mendukung ketahanan dan kinerja permukaan lintasan balap

The Gelora Bung Tomo (GBT) Circuit in Surabaya is one of the motorsport facilities with the potential to be developed into an international-standard racing circuit. However, the existing track geometry does not comply with the technical requirements established by the Fédération Internationale de l'Automobile (FIA) Grade 1 standards. Therefore, geometric
modifications are required to improve the safety, comfort, and performance of the circuit in accordance with the applicable standards. This study aims to design the geometric modification of the Gelora Bung Tomo Circuit based on FIA Grade 1 standards. The planning includes modifying the track configuration through horizontal geometric design, consisting of the determination of curve radii, transition curves, and superelevation, as well as vertical geometric design in the form of vertical alignment. In addition, a flexible pavement structure was designed based on the subgrade condition using the California Bearing Ratio (CBR) as the basis for pavement structural design. The research employed a secondary data collection method, including the existing circuit layout, topographic data, soil data, and a literature review of FIA Grade 1 standards and other technical references related to geometric and pavement design. The research stages consisted of track geometric analysis, horizontal and vertical alignment design, calculation of curve radii, transition curves, superelevation, and flexible pavement design based on the characteristics of the subgrade. The results indicate that the proposed geometric modification produced a circuit design with a total length of approximately 4.359 km and 11 turns, complying with the geometric requirements of FIA Grade 1 through adjustments to the track configuration, curve radii, transition curves, superelevation, and vertical alignment, thereby improving the safety, comfort, and overall quality of the racing circuit. Based on the analysis of the subgrade California Bearing Ratio (CBR), a flexible pavement structure was designed using the conventional asphalt pavement design method, while Stone Mastic Asphalt (SMA) was selected as the surface course material to provide enhanced durability and surface performance for racing applications.
