Abstract

Tingkat kecelakaan Pada Jalan Lintas Sumatra, Tarahan Kecamatan Ketibung Kabupaten Lampung Selatan cukup tinggi, kondisi jalan yang menurun, menanjak serta tikungan tajam kemungkinan besar mengakibatkan kecelakaan. Data kecelakaan Polres Lampung Selatan Tahun 2020 terjadi 30 kecelakaan lalu lintas mengakibatkan 12 orang meninggal dunia. Tujuannya untuk mengetahui jenis tikungan dan melakukan desai alternatif pada tikungan. Metode yang digunakan adalah data sekunder dan primer, dari pengumpulan data didapat gambar long section dan cross section. Dilakukan pengukuran jari-jari lingkaran pada tikungan, dilakukan perhitungan geometrik jalan berdasarkan Bina Marga. Jika jari-jari lingkaran ekisting belum memenuhi syarat standar maka dilakukan desain alternatif. Dari hasil perhitungan jenis ekisting tikungan bahwa dua tikungan yang belum memenuhi syarat Bina Marga, maka dilakukan desain alternatif pada tikungan tiga (T-03), dengan kecepatan Rencana (Vr) 60 Km/Jam, Jari-jari Lingkaran (Rc) 258,32 Meter, superelevasi 6,93 %, jenis tikungan Spiral-Circle-Spiral (S-C-S), dan pada tikungan lima (T-05), dengan kecepatan Rencana (Vr) 60 Km/Jam, Jari-jari Lingkaran (Rc) 130,00 Meter, superelevasi 9,80 % jenis tikungan Spiral-Circle-Spiral (S-C-S).Kata Kunci: Geometrik, Lengkung Horizontal, Superelevasi

Abstract

Increasing population leads to increased access needs roads as a means to move from a place. It takes a path feasible so that there are no obstacles that occur, it is expected to do road planning using pavement design Manual method (MDP) 2017 to get a design that is in accordance with its designation. This research done with the aim of knowing the existing condition of the road and determine design optimal pavement planning to fit the existing conditions on the road Poncowati-Purnama Tunggal Lampung Tengah Regency because on the road there are many public facilities needed people and road conditions are quite damaged. Research methods by means of calculate the volume of vehicle traffic and require primary data in the form of survey results of existing road conditions, and soil bearing capacity by using (Dynamic Cone Penetrometer) DCP. Secondary Data used is data (Average daily traffic) LHR. The results obtained carrying capacity conditions the soil is quite good with the smallest CBR results of 20.03 so it does not need improvement of subgrade condition on Poncowati-Purnama Tunggal road. Road conditions have been damaged and need to be repaired by using flexible pavement based on ESA calculation results Rank 4 and pavement design selection table in pavement design Manual (MDP) 2017, with the thickness of the upper foundation layer (LFA) 400 mm, Asphaltic Concrete Binder Course (AC-BC) 60 mm, and asphalt Concrete Wearing Course (AC-WC) 40 mm based on the calculation of ESA Power 5 and using reference to the design table in the pavement design Manual (MDP) 2017. There is a repair of total damage (reconstruction). Budget plan (RAB) wich estimate at Rp.9.291.416.000,-
