Pengaruh Penggunaan Abu Vulkanik sebagai Bahan pengisi (Filler) Campuran AC-WC terhadap Karakteristik Marshall

Abstract

Characteristic of this volcanic ash have relative different with dust dry ground that can be meet in dry season. Volcanic ash formed to the magma eruption in explosive. therefore volcanic ash can be filler in mixture asphalt ac-wc. The purpose of the research is analyze effect volcanic ash to the filler to mark marshall ac-wc. In The ac-wc mix which usually use portland cement filler, at this writing portland cement filler will be compared using volcanic ash filler to marshall test equipment in ac-wc mix by using the weight of the kind of aggregate. The research use experimental method that use in this laboratory by asphalt variation plan 5,0%; 5,5%; 6,0%; 6,5%; 7,0%. Samples used were each 3 pieces on each variation of asphalt content plan. Before the making of the specimen material aggregate and asphalt material should be tested and the test specimen using test equipment marshall test. For producing test specimens can be seen from the table the results of the combined aggregate gradation. The purpose of the test using test equipment marshall test is to find the value of stability, the weight of kind of density, and the optimum asphalt content. The results comparative studies of marshall the rest of the optimum asphalt content that is different can be concluded for the user of portland cement as filler in a mixture of ac-wc better value stability compared than volcanic ash as filler in a mixture of ac-wc 1105 kg compared to 1095 kg
