Abstract
Aspal modifikasi polimer merupakan suatu teknologi yang menawarkan
peningkatan durabilitas, mitigasi gangguan perkerasan jalan, dan mereduksi biaya
pemeliharaan dibandingkan dengan campuran aspal yang tidak dimodifikasi.
Perkerasan jalan dengan menggunakan aspal modifikasi memiliki ketahanan
terhadap fatigue, thermal cracking, rutting, serta stripping yang lebih baik
dibandingkan dengan yang tidak menggunakan aspal modifikasi (Yildirim, 2007).
Campuran aspal panas (HMA) merupakan metode yang paling umum digunakan.
Akan tetapi, akibat suhu pada proses pencampurannya yang tinggi menyebabkan
emisi gas rumah kaca yang dihasilkan. Hal ini meningkatkan kesadaran lingkungan
akan pemanasan global yang membuat teknologi campuran aspal hangat (WMA)
mulai dikembangkan mengingat reduksi suhu pada proses pencampurannya
mereduksi emisi gas yang dihasilkan. Penelitian dilakukan dengan penambahan
polimer Superplast dari Iterchemica kepada campuran aspal dengan kadar
pengujian dari 0%, 2%, 5%, 6%, dan 8% dan dengan kadar aspal 5,6% dengan
tujuan menentukan kadar penambahan polimer paling optimum pada metode HMA
dan WMA dengan menggunakan metode semi circular bending (SCB). Hasil
penelitian menunjukkan bahwa penambahan polimer pada campuran aspal mampu
meningkatkan kualitas campuran aspal dalam segi kekuatan dan kemampuannya
dalam menahan retak pada kadar penambahan polimer sebanyak 6% dengan ratarata peningkatan nilai parameter sebesar 77,7% untuk HMA dan penambahan kadar
polimer sebanyak 5% dengan rata-rata peningkatan nilai parameter uji sebesar
83,4% pada WMA./ Polymer modified asphalt is a technology that offers improvements in durability,
mitigation of pavement distress, and reduces life cycle costs when compared to
unmodified asphalt mixtures. Pavement that made with modified binders are more
resistant to fatigue, thermal cracking, rutting, and stripping than neat binders
(Yildirim, 2007). Hot mix asphalt (HMA) is the most commonly used method.
However, due to the high temperature of the mixing process, the emission of
greenhouse gases is produced. This increased environmental awareness of global
warming which made the warm asphalt mixture technology (WMA) began to be
developed considering that the reduction in temperature in the mixing process
reduces the resulting gas emissions. The research was carried out by adding
Superplast polymer from Iterchemica to the asphalt mixture with test levels of 0%,
2%, 5%, 6%, and 8% for asphalt content 5,6% of the total weight of the mixture
with the aim of determining the optimum polymer addition levels in the HMA and
WMA methods using the semi circular bending method. (SCB). The results showed
that the addition of polymer to the asphalt mixture was able to improve the quality
of the asphalt mixture in terms of strength and its ability to resist cracking at levels
of addition of polymer as much as 6% with an average increase in parameter values
of 77.7% for HMA and addition of polymer content by 5%. with an average increase
in the value of the test parameters of 83.4% at WMA.
