| Popis: | Asphalt quality improvement efforts starts from the construction of buildings, infrastructure and roads continue to be developed. This development will increase the need for material used. This study aims to (1) determine the effect of bagasse ash filler with concrete waste as a coarse aggregate on Marshall characteristics on asphalt concrete mixture, in terms of density, VIM (void in the mix), VMA (voids in mineral aggregates), VFA (void filled with asphalt), stability, flow (melting), and MQ (Marshall quotient). (2) As well as knowing the suitability of the Marshall test results with the requirements of Bina Marga 2010. This study uses an experimental testing method implemented by making test specimens following existing standards and conditions, as well as the use of bagasse ash as filler material and concrete waste as a substitute for coarse aggregate in asphalt mixture, with a variation of the percentage using bagasse ash filler with 0%, 5%, 10%, and 15% content. For each treatment, three samples were made. The results of testing the concrete asphalt mixture are: (1) density 2.16 gr/cc, VIM 11.56%, VMA 17.39%, VFA 33.91%, stability 3263.92 kg, flow (melting) 2.03 mm, MQ 2353.70 kg / mm. (2) Test results for all specimens, with the addition of bagasse ash filler as asphalt mixture filler, have met the 2010 Bina Marga requirements, as a minimum requirement for the highway, with stability values of more than 800 kg and flow values between 2 mm to 4 mm. |
