Menganalisa Pengaruh Pemakaian Additive Wetfix-BE pada Campuran Asphalt Concrete Binder Course (AC-BC)

Abstract

This research aimed to find out the effect of using additive wetfix-be in the AC-BC and to compare on amixed-use additive wetfix-be. This research discussed about the use of additives wetfix-be which was tested as an additional substance in the mixture of Asphalt Concrete Binder Course (AC-BC) and also applied technique of Marshall data analysis according to BinaMarga standard methods. It also applied experimental studies. Asphalt used was AC 60/70 of Pertamina production and the aggregate of stone crusser produced by PT. Karya Murni Perkasa which had a variation of asphalt content of 4%, 4,5%, 5%, 5,5% and 6%. Each variation of asphalt content was created 5 tests sample, and to get the optimum asphalt content (OAC) 5,70%, it used variation additional material additives of wetfix-be 0.3%. Then all specimens are examined of Marshall characteristic.This research result, every addition of additive wetfix-be into ACBC mixture made an increase for every Marshall characteristic. It could be observed an obvious difference within the mixture of additive. The differences were verified through observing additive 0.3% of optimum asphalt content and the effect showed that density value increased from 2,332 gr/cm3 to 2,355 gr/cm, stability value increased from 1206 kg to 1270 kg, Flow value increased from 3,27% to 3,43%, VFB value increased from 71,12% to 75,44%, Marshall Quotient increased from 363 kg/mm to 371 kg/mm. However the value of VIM and VMA decreased from 4,97% to 4,03% (VIM) and from 17,22% to 16,39% (VMA). Regarding to result acquired from the test of marshall characteristic, they fulfilled general specification of BinaMarga 2010.
