Abstract

Tanah lempung dengan plastisitas tinggi, kohesifitas yang besar berakibat fluktuasi kembang susut yang relatif besar. Hal ini yang menyebabkan kondisi jalan yang dibangun diatas tanah lempung mengalami kerusakan. Oleh karena itu dalam penelitian ini dilakukan perbaikan tanah dengan cara memperbaiki gradasinya yaitu mencampur tanah asli dengan pasir. Sampel tanah yang digunakan pada penelitian ini berasal dari Ruas Jalan R.A.Basyid, Kecamatan Jati Agung, Lampung Selatan pada STA 3+100 dengan variasi pasir 0%, 5%, 10% dan 15 % dari berat tanah. Pengujian pada penelitian ini adalah pengujian CBR dari efek pegembangan tanah, lalu dilakukan perhitungan tebal perkerasan dengan metode analisa komponen SKBI 2.3.26.1987 dan metode manual desain perkerasan jalan 2017. Pada penelitian inisampel tanah yang digunakan termasuk kelompok A-7-6(tanah yang buruk). Setelah penambahan variasi pasir, batas plastis tanah tersebut meningkat sedangkan batas cair dan indeks plastisitas menurun, hal ini mengakibatkan pengembangan tanah terjadi penurunan pada 15% pasir yaitu dari 0,62% menjadi 0,17%, sedangkan nilai CBR mengalami peningkatan yang signifikan pada pasir 15% yaitu dari 2,6% menjadi 26,0%. Dengan hal ini pada perhitungan dengan metode analisis komponen SKBI 2.3.26.1987 tebal lapis menjadi lebih tipis, pada 0% pasir yaitu tebal D1=7,5 cm, D2=25 cm dan D3=44 cm, sedangkan pada 15% pasir tebal D1=5 cm, D2=17 cm dan D3 tidak digunakan. Perhitungan dengan menggunakan metode manual desain perkerasan jalan 2017 pada variasi pasir 5%, 10%, dan 15% tidak perlu perbaikan jalan karena nilai CBR ≥6.

Abstract

Congestion problems are common in transportation, congestion can be caused by several things. The construction of the flyover is expected to be able to overcome congestion in the long term. This research was conducted to determine the effectiveness of the flyover construction on the Teuku Umar - ZA Pagar Alam road. This research was conducted during busy hours on Monday at the Teuku Umar road, ZA Pagar Alam and the nearest intersection.. From the results of calculations and analysis, it can be seen that the construction of an elevated bridge has no significant impact on the decomposition of the congestion problem in the Kedaton area and its surroundings, this can be seen from the level of service on all roads in the study area with a value of V / C Ratio <0.75. Meanwhile, the average degree of saturation obtained from the analysis of intersections with signal and no signal> 0.75. Construction of a flyover which illustrates that it will unravel traffic jams, in fact the performance of the flyover and the main road underneath has not increased. This needs to be addressed immediately considering the current traffic flow in Kedaton and its surroundings is already saturated. Therefore, the growth of vehicles is on time, and public transportation facilities need to be improved. So that people begin to switch to public transportation in order to reduce the incidence of congestion on these roads. Keywords : Road Performance, Degree of Saturation, Level of Road Service

Abstract

Concrete is the main material of rigid pavement that can withstand compressive strength and weak to tensile strength. Flexural tensile strength on rigid pavement itself is a benchmark in concrete pavement. To increase the value of the flexural tensile strength can be done by adding fiber to the concrete mixture. The purpose of this study was to determine the effect of the addition of plastic waste from plastic packaging made of polypropylene on the compressive strength and flexural tensile strength of concrete.In this study, the addition of used plastic waste pieces from packaged glass used fractional volumes of 0%, 0.1%, 0.3%, 0.5%, and 0.7% of the volume of concrete mixture. The samples for this study were a cylinder with a diameter of 15 cm and a height of 30 cm for the compressive strength test and a beam measuring 15 x 15 x 60 cm for the flexural tensile strength test. The test was carried out after the concrete had been 28 days old. The result of this research is the compressive strength decreased along with the amount escalation of the fiber to the concrete mixture. The flexural tensile strength maximum occur of the addition of plastic fibers at 2% volume fraction increased by 23,75% compared to flexural tensile strength of normal concrete. As a result of adding plastic fibers to the concrete mixture, it also decreased the workability of the concrete mixture

Abstract

Abstract One method of road infarstructure maintenance is dredging the old asphalt pavement to then be re-coated with a new asphalt pavement. The result of dredging old asphalt pavement is called RAP (Reclaimed Asphalt Pavement). RAP can be used as an aggregate substitution in the manufacture of new asphalt pavement layers, especially in the AC-WC (Asphalt Concrete-Wearing Course) layer by recycling. In addition to the utilization of RAP, improving the quality of road pavement also needs to be done by modifying paved mixtures by adding additives to the asphalt. The additive added in this study is ATK (Coconut Shell Charcoal). This study aims to determine the effect of the addition of ATK on the durability of RAP-based AC-WC mixtures. Furthermore, the immersion of the test object is carried out with a variation of 30 minutes, 1 day at a temperature of 60 °C. The effect of the addition of ATK to the RAP-based AC-WC mixture on its durability judging from the residual Strength Index (IKS) value shows that the residual strength value is getting smaller along with the increasing rap levels and ATK levels in the mixture, this can be caused because ATK is an organic material that is susceptible to the influence of water and RAP is a used asphalt pavement that has suffered damage due to road service. Keywords: AC-WC, RAP, Durability,Coconut shell charcoal Abstrak Salah satu metode pemeliharaan insfrastruktur jalan adalah pengerukan perkerasan aspal lama pada jalan untuk kemudian dilapis kembali dengan perkerasan aspal baru. Hasil dari pengerukan perkerasan aspal lama disebut dengan RAP (Reclaimed Asphalt Pavement). RAP dapat dimanfaatkan sebagai substitusi agregat pada pembuatan lapis perkerasan aspal baru khususnya pada lapisan AC-WC (Asphalt Concrete-Wearing Course) dengan cara daur ulang. Selain pemanfaatan RAP, peningkatkan kualitas dari perkerasan jalan juga perlu dilakukan dengan cara memodifikasi campuran beraspal dengan menambahkan bahan aditif pada aspal. Bahan aditif yang ditambahkan dalam penelitian ini yaitu ATK (Arang Tempurung Kelapa). Penelitian ini bertujuan untuk mengetahui pengaruh penambahan ATK terhadap durabilitas campuran AC-WC berbasis RAP. Selanjutnya perendaman benda uji dilakukan dengan variasi 30 menit, 1 hari pada suhu 60˚C. Pengaruh penambahan ATK pada campuran AC-WC berbasis RAP terhadap durabilitasnya ditinjau dari nilai Indeks Kekuatan Sisa (IKS) menunjukkan nilai kekuatan sisa yang semakin kecil seiring dengan bertambahnya kadar RAP dan kadar ATK dalam campuran, hal ini dapat disebabkan karena ATK adalah bahan organik yang rentan terhadap pengaruh air dan RAP adalah perkerasan aspal bekas yang telah mengalami kerusakan akibat masa layan jalan. Kata Kunci: AC-WC, RAP, Durabilitas, ATK
