PAVEMENT DESIGN THICKNESS OF GEMPOL – PASURUAN TOLL ROAD STA 13+900 UNTIL STA 20+900 USING PAVEMENT DESIGN MANUAL 2017

Gempol – Pasuruan toll road from STA 13+900 until STA 20+500, is one of the packages of the Trans Java Toll Road. This toll road was built to facilitate access to land transportation in the Java region. It has 6,6 km with a width of 4,6 meters on the right side and 4,6 meters on the left side section, each consisting of 2 lanes in 1 direction. The method used to design the pavement thickness is Manual Desain Perkerasan Jalan 2017. From the calculation results, knowing that the traffic volume is 3.165.089 ESA4 so that two types of pavement chosen, namely rigid pavement and flexible pavement. The calculation results of flexible pavement construction obtained a 40 mm AC WC, 60 mm AC BC, 80 mm AC Base 80, 380 mm grade-A aggregate foundation, 450 mm grade B aggregate foundation thickness, with a cost of discounted life cycle 413.515.845.291,70 rupiahs. For rigid, continuous without reinforced pavement with 290 mm plate thickness, 100 mm lean concrete, using tie bar (threaded) BJTU 24 length 70 cm D16 and dowel (plain) length 45 cm D36, with discounted life cycle cost is 398.732.419.535 rupiahs. So the type of pavement based on the lowest discounted life cycle cost is using the rigid pavement. Jalan Tol Gempol – Pasuruan STA 13+900 s/d STA 20+500 merupakan salah satu paket Jalan Tol Trans Jawa yang dibangun untuk mempermudah akses transportasi darat di wilayah Jawa, sepanjang 6,6 km dengan lebar jalan 4,6 meter ruas kanan dan 4,6 meter ruas kiri masing-masing terdiri dari 2 lajur 1 arah. Metode yang digunakan untuk perencanaan tebal perkerasan adalah Manual Desain Perkerasan Jalan Tahun 2017. Dari hasil perhitungan diketahui volume lalu lintas 3.165.089 ESA4 sehingga dipilih dua jenis perkerasan yaitu perkerasan kaku dan perkerasan lentur. Hasil perhitungan konstruksi perkerasan lentur diperoleh tebal AC WC 40 mm, tebal AC BC 60 mm, tebal AC Base 80 mm, tebal Lapis Pondasi Agregat kelas A 380 mm, dan tebal Lapis Pondasi Agregat kelas B 450 mm, dengan nilai discounted life cycle cost Rp. 413.515.845.291,70. Untuk perkerasan kaku bersambung tanpa tulangan dengan tebal pelat beton 290 mm, tebal lean concrete 100 mm, menggunakan tie bar (ulir) BJTU 24 panjang 70 cm D16 dan dowel (polos) panjang 45 cm D36, dengan nilai discounted life cycle cost adalah Rp. 398.732.419.535. Sehingga jenis perkerasan berdasarkan nilai discounted life cycle cost terendah adalah menggunakan perkerasan kaku.
