UJI MARSHALL PADA CAMPURAN ASPHALT CONCRETE BINDER COURSE (AC-BC) DENGAN TAMBAHAN PARUTAN BAN BEKAS

Abstract : Endurance of asphalt concrete pavement on traffic load and temperature depends on the type and composition of aggregates, asphalt and filler used. Many attempts have been made to improve the quality of the mixture, such as using modified asphalt. Modified asphalt made by mixing asphalt pen. 60/70 with addition material. In this research, we used crumb rubber as an aggregate substitute material on AC-BC mixture. This study aims to determine the influence of additional substitution of used crumb rubber. The first step of the research is to find the optimum asphalt content (OAC), then add the crumb rubber as an aggregate substitute material from 0%, 1%, 2%, 3%, 4% and 5% to the weight of the mixture. The results showed that the percentage of crumb rubber influenced Marshall parameters value, especially the value of stability, VIM and VMA at 5.285% asphalt content. The highest stability value was found in the mixture of 2% crumb rubber is 1128.48 Kg. The highest VIM value is in the 5% mixture of the used crumb rubber is 16.94%. The highest VMA value is in the 5% mixture of the used crumb rubber is 27.88% and the highest flow value is in the 5% crumb rubber mixture of 4.97 mm. However, in MQ value increase and decrease that happened very big. No big changes in the density and VFA values for all substitutions of crumb rubber. For the durability value of AC-BC mixture with crumb rubber variation 90% requirement only on crumb rubber 1%.Abstrak: Ketahanan perkerasan beton aspal terhadap beban lalulintas dan temperatur sangat tergantung pada jenis dan komposisi agregat, aspal serta filler yang digunakan. Banyak usaha telah dilakukan untuk meningkatkan kualitas campuran, salah satunya dengan menggunakan aspal modifikasi. Aspal modifikasi dibuat dengan mencampur aspal pen. 60/70 dengan bahan tambah. Pada penelitian ini bahan tambah yang digunakan adalah parutan ban karet bekas sebagai bahan pengganti agregat pada campuran AC-BC. Penelitian ini bertujuan untuk mengetahui pengaruh substitusi tambahan ban karet bekas sebagai bahan pengganti agregat. Tahapan awal penelitian adalah mencari Kadar Aspal Optimum (KAO), kemudian dilakukan penambahan parutan ban karet bekas sebagai bahan pengganti agregat mulai dari 0%, 1%, 2%, 3%, 4% dan 5% terhadap berat campuran. Dari hasil penelitian menunjukkan penambahan persentase parutan ban bekas mempengaruhi nilai parameter Marshall, terutama nilai stabilitas, VIM dan VMA pada kadar aspal 5,285%. Nilai stabilitas tertinggi didapat pada campuran 2% parutan ban bekas yaitu 1128,48 Kg. Nilai VIM tertinggi ada pada campuran 5% parutan ban bekas yaitu 16,94%. Nilai VMA tertinggi ada pada campuran 5% parutan ban bekas yaitu 27,88% dan nilai flow tertinggi ada pada campuran 5% parutan ban bekas yaitu 4,97 mm. Namun pada nilai MQ kenaikan dan penurunan yang terjadi sangat besar. Nilai Density dan VFA tidak terjadi perubahan yang besar untuk semua substitusi variasi parutan ban. Untuk nilai durabilitas campuran AC-BC dengan variasi parutan ban yang memenuhi persyaratan 90% hanya pada pemakaian parutan ban 1%.

Although there is a large population in the limited space of metropolitan areas in Taiwan, but many manholes are often set on the pavement, which impact the quality of the pavement service and lead to public complaints. In recent years, the manholes have been gradually buried under the pavement on policy, so as to improve administration performance of government. The construction quality at the location of manhole is not easy to control, and often leads to the pavement damaged. This study assesses the differences of the temperature changes at manhole location from the general asphalt concrete when paved with asphalt concrete using the infrared thermal imager. The study found that the use of infrared thermal imager can get the difference of temperature of asphalt concrete pavement between the manhole position and the non-manhole position, and also can determine the position and width of manhole, so as to help to the construction compaction and quality control. Furthermore, because the temperatures of pavement at manhole position and non-manhole position are different, when the pavement damaged and need to dig the pavement for maintaining, the infrared thermal imager can be used to find nonmetallic manhole for construction management reference.

Abstrak Campuran beraspal panas adalah kombinasi antara agregat yang dicampur merata dan dilapisi oleh aspal. Bahan penyusun dari campuran AC-BC hampir sama dengan bahan penyusun campuran aspal beton lainnya yaitu agregat halus, agregat kasar, filler dan aspal, yang membedakan adalah komposisi gradasi masing-masing lapisan. Penelitian ini membahas mengenai pengaruh penggantian Filler pada perkerasan jalan aspal beton AC-BC. Adapun tujuan dari penelitian ini adalah untuk mengetahui bagaimana pengaruh penggunaan Abu batu karang sebagai Filler dan pasir besi sebagai agregat halus terhadap karakteristik Marshall terhadap campuran Aspal AC-BC (Asphalt Concrete – Binder Course) terhadap stabilitas dengan metode Spesifikasi Umum Bina Marga 2010 Revisi 3, Benda uji yang didapatkan dari kadar aspal optimumnya adalah sebesar 6,2 % dan untuk benda uji penambahan variasi yang digunakan adalah abu batu karang dan pasir besi 25% - 50% -75% - 100%. Adapun Hasil dari pengujian di laboratorium di dapatkan hasil grafik yang naik turun, peningkatan nilai stabilitas didapat dari penambahan kadar variasi 25%, 50%, 75%, dan mengalami penurunan pada penambahan 100% variasi pasir besi dan abu batu karang, sedangkan nilai Density meningkat pada variasi 100%, VMA , VIM dan FLOW dengan penambahan pasir besi dan abu batu karang menurun pada variasi 50%-100%, sedangkan VFA, MQ terjadi Peningkatan yang tidak terlalu signifikan pada variasi 100%. Maka dapat disimpulkan variasi penambahan abu batu karang dan dan pasir besi sebagai pengganti filler dan penganti agregat halus memenuhi spesifikasi bina marga 2010 revisi 3. Kata Kunci: Spesifikasi 2010 rev 3, Filler, Agregat halus, Parameter Marshall Abstract Hot asphalt mixture is a combination of aggregates that are mixed evenly and coated with asphalt. The composition of AC-BC mixture is almost the same as the composition of other concrete asphalt mixers, namely fine aggregate, coarse aggregate, filler and asphalt, the difference is the gradation composition of each layer. This study discusses the effect of Filler replacement on AC-BC asphalt concrete pavement. The purpose of this research is to find out how the influence of the use of coral ash as fillers and iron sand as fine aggregate on the Marshall characteristics of the Asphalt Concrete - Binder Course asphalt mixture against stability with the General Reinforcement 2010 Revised 3 General Specifications method, The specimens obtained from the optimum asphalt content is 6.2% and for specimens the addition of variations used is rock ash and iron sand 25% - 50% -75% - 100%. As for the results of testing in the laboratory graph results get up and down, increasing the value of stability obtained from adding levels of variation 25%, 50%, 75%, and decreased in the addition of 100% variation of iron sand and rock ash, while the Density value increased at variations of 100%, VMA, VIM and FLOW with the addition of iron sand and coral ash decreased at a variation of 50% -100%, while VFA, MQ occurred a not too significant increase at 100% variation. Then it can be concluded that variations in the addition of coral ash and iron sand as a substitute for filler and substitute for fine aggregate meet the specifications of the 2010 revision 3.Keywords: 2010 rev 3 specification, filler, fine aggregate, Marshall parameters
