Study of Influence of Using Various Types of Filler on the Characteristics of Laboratory Mixed AC-BC and AC-WC 2010 Revised General Specification Version III

Abstract

Muhammad Reza A Maha and Harmein Rahman

Filler is a substance that serves as charger cavities of an asphalt mixture. Kinds of filler that can be used are: stone dust, lime extinguished, Portland cement (PC), etc. A small percentage of the filler for asphalt mixture does not mean that does not have a great effect on the properties of Marshall. The erruption of mount Sinabung some time ago at the Tanah Karo, North Sumatra lot leaving the material shed from the eruptions. Then there are around limestone hill in Sipoholon, North Tapanuli Regency, North Sumatera Province too many underutilized by society around. This paper attempts to compare the filler test result from authors with volcanic ash and lime ash againts rock ash as filler AC-BC by researchers previously with only using volcanic ash againts rock ash as filler in AC-WC. The goal from this paper is to knowing if the authors make a volcano ash and lime ash as a filler but this use in ACWC, would be same with the result marshall test requirement from researchers previously. In the step the authors collected result Marshall Test from researches previously. Then Compare with the authors research result [1-3], with provison mix parameter such as compareThe optimum asphalt content from each. Then compare from the result percentage marshall test from authors which make percentage filler from 0-6% and previously researches from 0-4%. The result from requirement marshall test from percentage marshall AC-BC from 0-6%. The Authors earn 4% while previous research AC-WC earn 3% which eligible from marshall test requirement. It can be concluded that make differences mix formula with Volcano ash againts Lime ash or without fly sand from percentage marshall test requirement. Then The layer is same with previous researchers is AC-WC. It would be same result by previously researchers where the result is 3% from percentage marshall test requirement from 0-6%. it could be happen because from gradation mixing factor from specification requirement from Highway departement in Indonesia.
