Geometri dan perkerasan exit taxiway mempunyai fungsi penting dalam proses perpindahan pesawat terbang dari bangunan bandar udara menuju landasan pacu maupun sebaliknya dalam waktu yang singkat, agar lalu-lintas pesawat dapat berjalan dengan lancar. Metode yang digunakan dalam perencanaan geometri dan perkerasan exit taxiway adalah Federal Aviation Administration (FAA) dengan pesawat rencana B767-400ER. Penelitian ini bertujuan membuat analisis rancangan geometri dan tebal perkerasan lentur exit taxiway Bandar Udara Internasional Ahmad Yani Semarang. Perencanaan geometris exit taxiway mengacu pada ketentuan-ketentuan ANNEX 14 yang dikeluarkan oleh ICAO. Hasil perhitungan tebal lapisan perkerasan secara urut dari bawah ke atas mencakup : CBR subgrade dengan kepadatan 6%, subbase setebal 73 cm, base course setebal 43 cm, dan surface course setebal 12 cm. Nilai PCN taxiway perkerasan lentur adalah 78. Perencanaan geometri exit taxiway dengan Wingspan 51.9 m dan Outer Main Gear Wheel Span 11 m, maka bandar udara tersebut termasuk pada Aerodrome Reference Code (ARC) 4D menurut Annex 14-Aerodrome dari ICAO.

Geometric and pavement of the exit taxiway has an important function in the process of moving from building aircraft towards the runway aerodrome and runway towards the building of an airport in a short time, so that air traffic will run smoothly. The method used in geometric and pavement of exit taxiway is the Federal Aviation Administration (FAA) with B767-400ER aircraft plan. This research aims to designing of the geometric and thickness of flexible pavement of exit taxiway Ahmad Yani International Airport in Semarang. Geometric design of exit taxiways refer to the provisions ANNEX 14 issued by ICAO. Results of calculations of pavement layer thickness in sequence from bottom to top includes: CBR subgrade with a density of 6%, subbase thickness of 73 cm, 43 cm thick base course, and the surface course of 12 cm thick. PCN value taxiway flexible pavement is 78. Geometric design of exit taxiway with Wingspan 51.9 m and Outer Main Gear Wheel Span 11 m, the airport is included in the Aerodrome Reference Code (ARC) 4D according to Annex 14 -Aerodrome of ICAO.
