PENGARUH PENGGUNAAN ASBUTON LAWELE TERHADAP KARAKTERISTIK CAMPURAN AC-BC DENGAN DURASI PERENDAMAN

Abstract

Road construction is currently increasing, but road pavement in Indonesia often experiences damage before
reaching the age of the plan. Asbuton Lawele as a road pavement material can not meet these guidelines. Meanwhile,
Lawele Asbuton deposit is still quite a lot, so the government wishes that Lawele Asbuton utilization can be carried out
to the maximum extent possible to support National Development, considering Asbuton Lawele as one of the country's
assets has a high economic value and deposit. Asbuton is a natural asphalt which is used as an additive to improve the
pavement layer of the road. The optimum bitumen content was obtained from Marshall testing. This study aims to
determine the performance of Marshall characteristics and the aggregate properties of asbuton-based hollow asphalt
mixtures. Mixture with immersion time variation with 30 minutes soaking standard with duration of 1 day, 3 days, 5 days
and 7 days, to see characteristic performance. The results obtained by the KAO value used in the AC-BC mixture with
variations in immersion duration that meet the mixed characteristic specifications of 6.4%, Marshall values due to
immersion resulted in a weight value, VIM, VMA and VFB did not experience significant changes along with increasing
immersion duration. Stability decreases along with changes in immersion. The decrease from 1 to 3 days was not too
significant from 3 to 5 and 7 days experienced a significant decrease.
