PENGARUH PENGGUNAAN ABU CANGKANG LOKAN, SERBUK BATA MERAH DAN ADITIF ANTI PENGELUPASAN PADA AC-BC
ABSTRACT: This study aims to
find a right formula of asphalt concrete binder course (AC-BC) hotmix by adding
the ash of lokans shell (ACL), red brick powder (SBM) and anti stripping agent.
Chemical analysis for ACL and SBM used SEM-EDX analysis. Hotmix sample testing
used Marshall method. The results showed that the ACL contains 34,77% carbon
and 65,23% calcium oxide. SBM was containing 34,09% alumina, 42,55% silica
dioxide, 0,73% potassium oxide, 1,98% titanium (IV) oxide and 20,65% ferrous
oxide. The addition of filler ACL SBM 50% + 50% from 10% cement filler; the
ingredient of anti stripping agent wetfix was 0,3% optimum asphalt content
(OAC), increasing the value of stability and flow mix AC-BC amounted to 51,5%
and 41,5%. Anova test results showed that the value of F for stability is of
9,21, the value of F for flow amounted to 19,19. Ftable at 99% confidence level
refers to the value of 7,82. This proves that the addition of ash shell
seashell, red brick powder and additive anti sloughing have significant effect
on the stability and flow value mix AC-BC. Durability and flexibility of road
construction types AC-BC for the better.
