PENGARUH BUBUK TALK SEBAGAI BAHAN FILLER PENGGANTI PADA CAMPURAN AC-WC

The use of filler aims to improve the density of the filler and stability a mixed mass. Because of the importance of filler uses program needs to be done on a mixture of substitute innovation filler. One of them is by making use of the powder talk. The purpose of this research to know the worthiness of the powder talk as a substitute for on a mixture of filler AC-WC by seeing characteristic of Marshall, Indirect Tensile Strength, and Cantabro. Research in 4 stage,in the first testing material properties consisting of testing aggregate, asphalt, and filler. The second phase determined asphalt steady on the proportions filler a substitute for 0%, 25%, 50%, 75%, and 100% filler powder talk. The third stage conducting a Marshall, Indirect Tensile Strength, and Cantabro. The stage to four, discussion and the conclusions from the carried out according to the requirements and methods of Bina Marga in 2010. The research results show that powder filler talk can be used as a substitute filler in a AC-WC mixture. The test results show that mix of Marshall had a change characteristic Marshall quite significant that is on the ability to support the mixture is accelerating and flexibility is increasing. It can be seen in the value of increased stability, flow increased, the value of MQ increased, VITM experienced an increase in, there was an increase in density, VFWA decrease and VMA has experienced a fall in. The ability to hold the force of attraction (Indirect Tensile Strength) AC- WC mixture as an increase in the proportion powder increased filler talk to on the replacement filler 50%, after that the its has decreased as you get the replacement filler 75%, and 100%. The Cantabro on a mixture of AC-WC using talk filler powder as a substitute decrease, with the increasing number of a powder percentage filler talk.
