Jalan merupakan prasarana yang memiliki peranan sangat penting dalam sektor perhubungan darat. Jalan
Ir. Moh. Taher, Lueng Bata, Banda Aceh merupakan salah satu jalan yang mengalami penurunan kualitas
permukaan jalan. Penelitian ini bertujuan untuk mendesain kembali tebal perkerasan lentur pada Jalan Ir. Moh.
Taher menggunakan metode Manual Desain Perkerasan 2017 dan Manual Desain Perkerasan 2024. Berdasarkan
ketentuan MDP 2017 dan MDP 2024, nilai CBR tanah dasar diasumsikan sebesar 6% dengan tujuan agar tidak
diperlukan perbaikan. Dengan umur rencana 20 tahun pada MDP 2017 diperoleh nilai CESAL 4 sebesar 0,152 x
106 kend/hari dan pada MDP 2024 diperoleh nilai CESAL 5 sebesar 0,118 x 106
kend/hari. Nilai tersebut berada
0,1- 4 juta, maka struktur perkerasan yang digunakan yaitu AC/HRS dengan lapis fondasi dan perbaikan tanah
dasar (dengan stabilisasi semen). Berdasarkan Tabel 2.15 dan Tabel 2.33 didapatkan tebal lapis perkerasan untuk
Subgrade Classification 2 (SC2) = 0,1 - 0,5 juta adalah : HRS WC, AC WC = 50 mm, lapis fondasi agregat kelas A
= 220 mm, lapis fondasi agregat kelas B = 150 mm, dan stabilisasi tanah asli hingga mencapai CBR ekuivalen 6 %
= 200 mm. Berdasarkan perhitungan, hasil desain tebal perkerasan lentur kedua metode adalah sama.

Roads are infrastructure that have a very important role in the land transportation sector. Jalan Ir. Moh. Taher, Lueng Bata, Banda Aceh is one of the roads that has experienced a decline in road surface quality. Therefore, this study was conducted to redesign the thickness of flexible pavement on Jalan Ir. Moh. Taher using the 2017 Pavement Design Manual and 2024 Pavement Design Manual methods. Based on the provisions of the 2017 MDP and 2024 MDP, the CBR value of the subgrade is assumed to be 6% with the aim that no repairs are needed. With a design life of 20 years in the 2017 MDP, the CESAL 4 value was obtained of 0.152 x 106 vehicles/day and in the 2024 MDP the CESAL 5 value was obtained of 0.118 x 106 vehicles/day. These values are 0.1-4 million, so the pavement structure used is AC/HRS with a foundation layer and subgrade repair (with cement stabilization). Based on Table 2.15 and Table 2.33, the thickness of the pavement layer for Subgrade Classification 2 (SC2) = 0.1 - 0.5 million is: HRS WC, AC WC = 50 mm, aggregate base layer class A = 220 mm, aggregate base layer class B = 150 mm, and stabilization of the original soil to reach an equivalent CBR of 6% = 200 mm. Based on the calculation, the design results of the flexible pavement thickness of the two methods are the same. Keywords: flexible pavement, MDP 2017, MDP 2024, CESAL, CBR, cement stabilization
