| Summary: | Jatropha oil extraction process produces waste in the form of oilcake seed,
this waste will interfere with the environment if not properly managed and
utilized. Amid the difficulty of getting dust rocks that have been widely used as a
filler mixture of asphalt, then try other alternatives as a filler material in the
asphalt mix, using a jatropha oilcake seed to ashes through the combustion
process, expected later ash oilcake seed jatropha can be used as a filler and was
able to fix characteristics of asphalt mixtures, which can help the government in
using recycled materials to produce useful products.
The research was conducted by making specimens HRS-Base mixture
with 5 filler variation, namely variation 1 (100% dust rock + 0% ash oilcake seed
jatropha), variation 2 (75% dust rock + 25% ash oilcake seed jatropha), variation
3 (50% dust rock + 50% ash oilcake seed jatropha), variation 4 (25% dust rock +
75% ash oilcake seed jatropha), variation 5 (0% dust rock + 100% ash oilcake
seed jatropha), the testing was done by Immersion Marshall test with 0.5 and 24
hours, and Indirect Tensile Strength test.
Optimum asphalt content for a variety of 1, 2, 3, 4, and 5, respectively
6.5%, 6.7%, 6.9%, 7.2%, and 7.4%. The use of ash oilcake seed jatropha in the
mix HRS-Base cause the value of density, VMA, stability, and Marhall Quotient
decreases, while the value of flow increases, and the value VITM, and VFWA no
significant changes, along with increased use of filler ash oilcake seed jatropha.
Immersion Index value generated for variations 1, 2, 3, 4, and 5 respectively
94.4%, 90.5%, 88.6%, 81.4%, and 82.2%. While the value of Tensile Strength
Ratio (TSR) is generated for variations 1, 2, 3, 4, and 5 respectively 90%, 84%,
77%, 73%, and 68%. |
