Porous asphalt is asphalt mixture using open gradation dominated by coarse aggregate to produce a large enough cavity. Bottom ash waste produced by a boiler used in the extraction process of palm oil into crude palm oil. Shells and pulps that has been burned at high temperature between 500°C to 700°C will later become of boiler bottom ash. The aim of this study was to inspect the performance of Porous Asphalt Mixture characteristics which combining bottom ash boiler and cement as filler using Retona Blend 55 as a binder. The specimen preparation were designed by the Australian Asphalt Pavement Association (AAPA) method by parameter of Cantabro Loss (CL), Asphalt Flow Down (AFD), Voids In Mix (VIM), Stability and Marshall Quotient (MQ). The Optimum Asphalt Contain (OAC) obtain was used to prepare specimens within OAC with variation 50 % bottom ash boiler and 50 % cement as filler. The result of study showed that the OAC obtained 6%. Almost all parameter values were meet to the required specification of AAPA (2004). The value of CL is 9.25 %, AFD value is 0.19%, Stability 573.27 kg, flow 4.7 mm and VIM 12.29%. The value of VIM not meet to required specification (18%-25%).
Asphalt is one of the non-renewable natural resources. It is necessary to conduct various studies regarding alternative materials can be used as a substitute for asphalt. Crude palm oil (CPO) has almost the same texture and properties as asphalt, when it is heated it will melt so it can be substituted as a binding agent in the AC-WC layer. Based on the background, this study aims to analyze the effect of 50% CPO substitution and 50% pen 60/70 on the AC-WC layer. This research is based on the Public Works Department General specifications in 2010 using the marshall method by varying 50% CPO and 50% pen 60/70. Variation of 50% CPO and 50% 60/70 pen get Asphalt Optimum Content (AOC) value of 4.5% from the test results of 15 test specimens and 6 specimens using AOC. The results of the test with a 30-minute immersion (stability) all the characteristics meet the marshall parameters that are implied, namely: a stability value of 842 kg, a Flow of 3.1 mm, a VIM of 4.64%, a VMA of 15.30%, a VFB of 69, 67% and the MQ value of 271.51 kg / mm. Marshall testing with a 24-hour immersion (durability) did not meet the specifications required so that this pavement is not durable.
Ekspansi ekonomi sebagian besar didorong oleh infrastruktur. Salah satunya adalah pembangunan jalan yang sanggat berpengaruh terhadap mobilitas ekonomi antar daerah yang ada di Indonesia. Akan tetapi, masalah keselamatan dan kesehatan kerja (K3) masih sering terjadi pada proyek konstruksi, hal ini ditujukan dengan hasil angka kecelakaan kerja yang masih tinggi. pekerjaan konstruksi memiliki risiko kecelakaan kerja, termasuk pekerjaan jalan yang tidak boleh mengesampingkan resiko yang terjadi.. Maka dari itu maksud dari penelitian ini untuk membandingkan penerapan sistem K3 pada jalan Simpang Peut-Kuta Makmue dengan Jalan Lamie-Sarong Ijo. Manfaat dari penelitian adalah agar mengetahui tentang penerapan sistem K3 dengan metode analisis perbandingan pada kedua proyek sehingga dapat mengurangi resiko kecelakaan pada proyek konstruksi.. Penelitian ini menggunakan metode deskriptif dengan pendekatan kualitatif. Berdasarkan hasil dari penelitian ini perbandingan antara kedua proyek menunjukan bahwa perbedaan tersebut dipengaruhi nilai K3 pada proyek Jalan Lamie-Sarang Ijo dianggap lebih baik dari pada proyek jalan Simpang Peut-Kuta Makmue. Maka dari itu disarankan setiap orang yang terlibat pada proyek konstruksi tetap memperioritaskan keselamatan dan kesehatan kerja (K3), serta pihak manajemen terus memberikan pemahaman serta anjuran terhadap pekerja agar selalu mengikuti prosedur keamanan proyek yang ditetapkan
