Pengaruh Variasi Panjang Serat Tebu Sebagai Bahan Stabilizer Terhadap Karakteristik Campuran Stone Matrix Asphalt (Sma)

---

ABSTRACT
Stone Matrix Asphalt mix is an asphalt mix that excels in resistance to permanent
deformation (rutting) due to its interlocking structure. However, this mix is costly
and requires high amounts of asphalt and stabilizer. The use of stabilizers in this
mixture serves to prevent draindown (the separation of asphalt from the mixture)
in the form of cellulose fibers or polymer fibers, which is a common problem in this
type of mixture. Cellulose fibers can be synthetic or natural, with natural fibers
having the potential to be an environmentally friendly and economical alternative
stabilizer to synthetic fibers. This study aims to determine the effect of variations in
sugarcane fiber length as a stabilizer on the characteristics of stone matrix asphalt
mixtures as seen from the results of draindown, Marshall stability, indirect tensile
strength, and Catanbro tests. The method used in this study was an experimental
method using sugarcane fibers with variations in length of 1-2 mm, 2-4 mm, 4-6
mm, and viatop, with a constant fiber content of 0.3% of the total weight of the
mixture. The results showed that the length of sugarcane fiber significantly affected
the characteristics of SMA. Draindown testing of 4-6 mm long sugarcane fiber had
a value of 0.021% lower than the other variations. Marshall testing of 4-6 mm long
sugarcane fiber increased the stability value compared to the other variations with
a value of 696.745 kg. Sugarcane fibers 4-6 mm long in the ITS test increased the
ITS value by 502.152 kPa, which was close to the mixture using viatop, which was
511.427 kPa. Sugarcane fibers 1-2 mm long in the Catanbro test had a catanbro
loss value of 0.548% lower than the other variations.
