Abstract
Many attempts have been made to improve the quality of the mix, one of them by using the bitumen modification. In this study, the added material used is Rice Husk Ash. The added material was expected to improve the quality of asphalt and characteristics of the asphalt concrete pavement desired. This study aims to determine the effect of the Rice Husk ash as additive into bitumen 60/70 penetration of the bitumen characteristics, and determine the performance of a mix of -Wearing Course Asphalt Concrete (AC-WC) using bitumen with added Rice Husk Ash.This research, using the Marshall method that used in some variation of Rice Husk Ash content and asphalt content. Variations are used for grade Rice Husk Ash is 4%, 6%, and 8% by weight of bitumen and asphalt content 4%, 4.5%, 5%, 5.5%, and 6%.These results indicate that the physical addition of Rice Husk Ash making asphalt becomes brittle and adhesiveness decreases can be seen from the decline in value of 1.17% asphalt penetration at levels of 0% to 8%. Judging from the test results obtained that Marshall Stability value decreased by 28.57% of the value of the highest stability.
