Abstract

Tanah lempung apabila digunakan untuk subgrade perlu dilakukan perbaikan tanah untuk menaikkan daya dukung tanahnya, salah satu cara dengan perbaikan sifat fisis. Perbaikan sifat fisi yaitu dengan mengganti subgrade dengan tanah yang memiliki daya dukung yang baik yang disebut sebagai tanah timbunan. Pemadatan tanah timbunan di lapangan pada kondisi ideal yaitu pada saat kadar air optimum, permasalahannya di lapangan kondisi ideal ini tidak selalu bisa diperoleh. Dimana pemadatan dapat terjadi pada kondisi kering (dibawah kadar air optimum) dan pada kondisi basah (diatas kadar air optimum). Tujuan penelitian mengetahui karaktersistik kuat geser pemadatan tanah timbunan untuk subgrade terhadap perubahan kadar air. Metode penelitian adalah pengujian kuat geser laboratorium SNI 3420:2016. Hasilnya diperoleh nilai kohesi meningkat pada kondisi kering (OMC-2%) dan kondisi basah (OMC+2%). Nilai sudut geser turun pada kondisi basah (OMC+2%) dan kondisi kering (OMC-2%). Kesimpulan terjadi penurunan sudut geser apabila dipadatkan dalam kondisi basah dan kering dari kadar air optimum.

Abstract

Lignin is a cellulose substance contained in soft woody plants and can be used as a dispersing and stabilizing agent in asphalt extenders, dyes and concrete . Lignin can be easily found so it has the potential to become renewable energy. It is hoped that the use of lignin from plants can become a new innovation regarding environmentally friendly biomaterials. The aim of the research is to analyze the marshall characteristics of asphalt concrete mixtures. The research method used was an experimental study in the laboratory based on Bina Marga 2018 Revision II 2020. The research used variations in lignin substitution of 0%, 25%, 50%, 75% and 100% for filler weight. Before making the test object, the lignin that will be used as a filler replacement is first subjected to XRF testing to determine the level of lignin used. Marshall testing is carried out after soaking for 24 hours and then marshall testing at a temperature of 60℃. The research results showed that every 25% lignin substitution in the asphalt concrete mixture tended to increase the VIM and VMA parameters. For the stability parameters, flow, MQ and density tend to decrease with lignin substitution, but the results obtained still meet the 2018 Bina Marga Revision II 2020 requirements. In the VFWA and VITM parameters there are no variations that meet the requirements. The research conclusion is that lignin is not recommended as a substitute for filler in asphalt concrete mixtures.

Abstract

Buton Granular Asphalt has properties to improve pavement characteristics because the material from Buton Granular Asphalt contains fine grains of material that provide strength to the road pavement so that with the increase in the strength of this pavement layer, it will affect the wear of the pavement due to the frictional force of the wheels on the road pavement. So it is necessary to do the properties and characteristics of the strength of the asphalt concrete mixture with the use of Buton Granular Asphalt. This research uses Buton Granular Asphalt as an added material for Asphalt Concrete – Wearing Course (AC-WC) pavement layers. The method used in this research is an experimental study in the laboratory by looking at the parameters and national standards set in laboratory testing. Buton Granular Asphalt is an asbuton product that has bitumen content between 20-25%. From the results of the Optimum Asphalt Content (KAO) test, the optimum asphalt content value is 5.64%. After getting the Optimum Asphalt Content, the test object was made with the addition of Buton Granular Asphalt, variations were made with values of 0%, 1%, 2%, and 3% of the asphalt weight. After making the test object, the cantabro test was carried out. From the results of the study, the value of weight loss at 0% levels was 8.82%, 1% levels were 5.18%, 2% levels were 2.46% and 3% levels were 1.84%. The results of this study indicate that the use of Buton Granular Asphalt material with a content of 3% has the lowest weight loss value, with the use of Buton Granular Asphalt as an added material has a high resistance to wear and tear. This indicates that adding Buton Granular Asphalt can make the pavement resistant to wear and tear caused by vehicle wheel friction and because the content of Buton Granular Asphalt consists of a fine material that can make the interlocking of the pavement mixture stronger.

Abstract

Tanah lempung sering digunakan sebagai tanah dasar pada konstruksi jalan, tetapi memiliki karakteristik plastisitas yang tinggi sehingga mempengaruhi daya dukung tanah. Salah satu parameter yang digunakan untuk menilai daya dukung tanah adalah California Bearing Ratio (CBR) sedangkan sifat plastisitas tanah dinyatakan melalui Indeks Plastisitas (PI). Penelitian ini bertujuan untuk menganalisis korelasi anatara Indeks Plastisitas terhadap nilai CBR pada tanah lempung. Metode penelitian dilakukan melalui pengujian laboratorium yang meliputi pengujian Atterberg dan pengujian CBR laboratorium. Hasil penelitian persamaan regresi (R²) dikategorikan sangat baik karena > 0,75, dimana nilai R² yang diperoleh sebesar 0,8421. Korelasi yang diperoleh adalah sangat kuat yaitu 0,80 – 1,00, karena nilai R diperoleh sebesar 0,917. Kesimpulannya tanah lempung menunjukkan korelasi sangat kuat dimana semakin tinggi nilai Indeks Plastisitas (PI) tanah maka nilai CBR akan semakin rendah. Saran mengambil sampel lebih banyak lagi pada lokasi yang sama agar mendapatkan model regresi yang lebih valid lagi. Kata kunci: Daya Dukung Tanah, Tanah lempung, CBR, Indeks Plastisitas
