Abstract

The purpose of this study is to find out whether the addition of plastic waste Low Density Polytlene (LDPE) as a alternative subsitution of Marshall characteristic on AC-BC mixture. First study done by made sample, the optimum asphalt contentused is  5,75%, and then made sample use plastic waste contenct was 10%, 11%, 12%, 13%, and 14%. The best result of Marshall Test was obtained at 14%, while VIM and VFA out of range of spesification.

Abstract

Palembang Toll Development Project - Simpang Indralaya is built on swamp land. The subgrade of this road is soft clay soil that has low bearing capacity of soil. Low bearing capacity of the soil will cause severe damage to the pavement on the soil heap. Therefore it is necessary to strengthen the base soil to be able to withstand and avoid sliding because it does not decrease.In this final project, there will be comparative analysis of 2 (two) alternatives to improve the embankment in reaching the same degree of consolidation. The first alternative is traditional preloading method and second alternative is vacuum preloading method.From the calculation results, obtained by using vacuum preloading method, the time required to achieve the same degree of consolidation can be shorter than the traditional preloading method.

Abstract

Pembangunan infrastruktur dari suatu daerah merupakan tolak ukur dari perkembangan otonomi daerah. Pembangunan jalan pada suatu ruas jalan disebabkan oleh kebutuhan, juga meningkatnya jumlah kendaraan yang melewati suatu daerah tersebut. Kebutuhan yang dimkasudkan seperti jalan telah rusak ataupun tidak ada akses jalan sama sekali untuk menuju kesuatu daerah seperti yang terjadi di Ruas Jalan Pampangan ? Lebung Batang STA 0+000 ? 6+039 Kabupaten Ogan Komering Ilir Provinsi Sumatera Selatan ini.Didalam merencanakan desain geometrik jalan raya, hal-hal yang menjadi acuan dalam perencanaan meliputi perhitungan alinyemen horizontal, alinyemen vertikal, serta menetapkan perkerasan apa yang akan digunakan.Dari hasil perhitungan-perhitungan diatas maka Jalan Pampangan-Lebung Batang ini merupakan jalan Arteri kelas I dengan kecepatan rencana jalan 60 km/jam, dan pada jalan ini menggunakan 4 buah tikungan diantaranya, 4 Full Circle, 2 Spiral Circle Spiral dan 2 Spiral Spiral. Lapisan permukaan jalan menggunakan Perkerasan Rigid dengan tebal lapisan 29,5 cm, sedangkan lapisan pondasi bawah menggunakan Lean Concrete dengan tebal 10 cm dan Aggregat Kelas A dengan tebal lapisan 15 cm. Pembangunan ruas jalan ini dilaksanakan dalam waktu 266 hari kerja dengan total dana Rp 123.828.951.800,00 (Seratus Dua Puluh Tiga Miliyar Delapan Ratus Dua Puluh Delapan Juta Sembilan Ratus Lima Puluh Satu Ribu Delapan Ratus Rupiah)Kata kunci : Jalan, Desain Geometrik, Tebal perkerasan kaku

Abstract

Abstract. Porous asphalt is an alternative in flexible pavement which is considered to make water seep into the soil. In previous research have been tested the mixture of  porous asphalt that meets porous asphalt porosity requirements, but found the weaknesses that the stability is still lower than the standard required. Based on result obtained before, the study is aimed at investigating the use of mixture composition variable with different percentages until the optimal conditions were obtained, namely making a normal mixture, 15%, 18.75%, 22.5%, 26.25%, 30% as sand composition reduction. The percentage of sand reducted from previous composition with different asphalt variations. Tests are carried out using the Marshall method. Sequence of tests show that the materials used for experiment meet the requirement.  Optimum Asphalt Content obtained for the mixture are 6% of the total mixed weight. The best Marshall characteristics for AC-WC porous asphalt obtained are at the percentage of 26.25% sand reduction.

Abstract

Styrofoam waste presents the environment issue because it is difficult to decompose. As an effort to recycle this pollutant, styrofoam can be utilized as an additive in asphalt concrete mixture. The use of additives aims to create a flexible pavement layer having good performance and meet the requirements. The purpose of this study is to find out whether the addition of styrofoam can improve the quality of asphalt mixtures, and look for alternative additives that can increase asphalt pavement performance. In this study, researchers used food container styrofoam as an addition and incorforated into Asphalt Concrete Wearing Course (AC-WC) mixture. The styrofoam content was 6.5%; 6.75%; 7% ; 7.25%; and 7.5% of asphalt weight. The optimum asphalt contentused is 5.5%. The value of the optimum stability was 3126,002 kg, found at 7.25% of styrofoam content. The best results of Marshall test was obtained at 6.5% of styrofoam content  with stability value  1362,045 kg, VIM value 4,96%, VMA 15,025%, VFA 67,800%, flow 3,44 mm, and MQ 416,338 kg / mm.
