Abstract

In a pavement mixture, filler has a significant effect because its functions as a cavity filler in the mixture. The fillers commonly used are Portland cement, stone ash or fly ash which are relatively expensive. Therefore it is necessary to use alternative filler removal materials but not reduce the quality of the pavement mixture. In this study, the filler used was waste burning rice husk ash because it has a high silica content which is almost the same as Portland cement. The purpose of this study was to determine the effect of using rice husk ash filler in a mixture of AC-WC asphalt types. In this study the optimum asphalt content determination was carried out at asphalt levels 5%, 5.5%, 6%, 6.5% and 7%. The proportion of rice husk ash used were 0%, 2%, 4%, 6% and 8%. The specifications used follow the Bina Marga 2010 Revision 3 standard with the Marshall method. The results of this study indicate that the AC-WC mixture using rice husk ash filler has better stability than not using rice husk ash filler. The highest stability value is found at 6% filler level which is equal to 1701.00 kg. The recommended level of rice husk ash for AC-WC mixture that is according to specifications is 6% because it has a better value of stability, flow, VIM, VMA, VFA, MQ.Keywords: Rice husk ash, Filler, AC-WC, Bina Marga Specification 2010 Revision 3

Abstract

In the road pavement mixture, filler has a significant effect because it functions as a cavity filler. One of the filler that is commonly used is fly ash. Fly ash is a coal combustion waste that can be utilized and has a high silica content so as to improve the quality of the road pavement mixture. The purpose of this study is to determine the durability of the AC-WC layer using fly ash fillers in peat water environments. The proportion of fly ash used was 0%, 2%, 4%, 6% and 8%, each variation of fly ash was immersed for 0.5 hours, 24 hours, 48 hours, 72 hours, and 96 hours in peat water. The specification used follows the 2018 Bina Marga standard using the Marshall method. The results show that the AC-WC mixture submerged in peat water would experience a decrease in the value of stability and durability of the mixture. The highest stability value is 1308.08 kg at 0.5 hour immersion, while the lowest stability value at 96 hours immersion is 927.42 kg. However, the use of fly ash as filler will increase the stability and mixture values. The highest stability value for the AC-WC mixture is 1308.80 kg at 6% fly ash variation. This is caused by fly ash being able to maintain stability and durability when submerged in peat water. The optimum variation of fly ash filler which can be added to the AC-WC mixture is 6% of the total weight of the aggregate. This value is based on a high stability value compared to other variations of 1308.80 kg. As for the RSI value, the AC-WC mixture is able to withstand damage up to 48 hours which is equal to 90.07%Keywords: Fly ash, Filler, AC-WC, durability

Abstract

Asphalt is one of the materials used in road construction, this material was chosen because it can produce flexible, safe and comfortable pavement. One of the functions of adding fillers is to minimize the use of asphalt base materials, where this filler has a significant effect because it functions as a cavity filler. The filler used is factory waste, namely fly ash and bottom ash. Fly ash is the residue from burning coal in power plants. Bottom Ash as well as fly ash is the result of burning coal, the ash that is produced when burning coal that settles. The purpose of this study was to determine the effect of using FABA waste (fly ash and bottom ash) on the quality of the road surface construction layer (top layer). The proportions of fly ash and bottom ash used are 2%, 4%, 6%, 8% and 10% of the total weight mixture of the mixture where each variation of fly ash is 55%: 45% bottom ash. Marshall characteristic test results show that the addition of fly ash and bottom ash to the AC-WC mixture can increase the value of stability and the of void filled with asphalt (VFA) and can reduce the value of void in the mixture (VIM) with certain filler levels according to the tests that have been carried out which can be used in the field, namely variation 2 %, 4%, 6% and 8%. The optimum variation of fly ash and bottom that can be added to AC-WC mixture 2% of the total aggregate weight. This value is based on the high stability value compared to other variations is 1654,74 kg. Keywords: AC-WC, Bottom Ash, Filler, Fly Ash, Top Layer.

Abstract

Petroleum industry has an important role in supplying fuel necessaries. In process to produce pretoleum crude oil into various of petroleum based products also emerged waste products includesolids, liquids and gases. Solid waste products which found from poduction activities of the industry produce called Oil Sludge. Oil sludge is categorized as hazardous and toxic waste (B3) because the characteristic and the concentration can contaminate the environment. This research aims to investigate the potential of oil sludge as a partial replacement of asphalt in Asphalt Concrete -Binder Course (AC-BC). In this study the variation of oil sludge addition was 0%, 4%, 6% and 8% of the weight of asphalt. The addition of oil sludge decreased the optimum asphalt content (OAC) and increased the unit weight of the asphalt concrete mixture. This is caused by the fine grains contained in the oil sludge. Based on the Marshall characteristics test results, the maximum allowable content of oil sludge that could be used was 4% with 6.65% of OAC and 948,03 kg of average stability value which satisfied the specifications of Bina Marga 2010 Revision 3.Keyword : oil sludge, asphalt concrete, AC-BC, marshall, Specification of Bina Marga 2010 Revision 3
