Abstract

The purpose of the study was to analyze the results of the physical properties of the clay used and to analyze the effect of adding oil palm shell ash to the clay on the direct shear test. From the results of testing the physical properties of the soil, the soil samples came from Jalan Yusuf Bauty, District. Somba Opu, Gowa Regency is an organic clay soil with moderate plasticity, according to the USCS soil classification system, the soil is classified as fine-grained OH group (organic clay with moderate plasticity and according to the AASTHO system the soil sample includes A-7-5. Direct Shear Test) with the addition of oil palm shell ash from the three samples, it can be seen that oil palm shell ash is able to increase cohesion (c) at each percentage addition of oil palm shell ash, but at the shear angle there is an erratic addition at each percentage addition of shell ash. palm oil, this is because oil palm shell ash only has tensile stress as a binder. From the results of research conducted, the addition of oil palm shell ash has an effect on shear strength, this shows that oil palm shell ash can be used for stabilization,

Abstract

Tujuan penelitian berfokus pada pengujian karakteristik campuran Laston Lapis Aus, Agregat yang diambil kemudian yang akan dikaji ialah agregat dati batu sungai batupapan Kabupaten Luwu. Metode yang digunakan dalam penelitian ini antara lain menguji sifat agregat kasar, agregat halus dan filler , setelah itu dilakukan perancangan campuran Laston Lapis Aus setelah itu dilakukan pengujian Marshall adapun pengujian marshall yang dilakukan ada 2 ,pertama Marshall konvensional untuk mendapat nilai karakteristik kemudian yang kedua marshall immersion untuk mendapat nilai Void in mix dan Stabilitas Marshall Sisa yang menggunakan kadar aspal optimum. Hasil penelitian setelah dilakukan telah diperoleh nilai karakteristik aggregat yaitu agregat sungai batupapan Kabupaten Luwu telah memenuhi persyaratan Bina Marga 2018 sebagai bahan dalam perkerasan jalan. Hasil penelitian ini telah lolos Uji Marshall dengan Kadar aspal 5.00% – 7.50%, kemudian padar kadar aspal optimum 7.50% didapatkan nilai Stabilitas Marshall Sisa yaitu 97.97% yang telah lolos persyaratan 90.00%.
