Summary: | Recently the increase in traffic growth causes premature damage to
pavement, then the need for an innovation to overcome these problems, one of
which is by using modified asphalt. Modified asphalt used in this study research is
a blend of asphalt BNA 75:25:10R uses a mixture Split Mastic Asphalt (SMA),
which is a mixture of high school that has a mix of good characteristics for dense
traffic and have high stability. Expected in this study Asphalt blend BNA
75:25:10 R can have the characteristics of a good asphalt material that can replace
conventional asphalt.
The study research was conducted by making specimen mix Split Mastic
Asphalt (SMA) using BNA Blend 75:25:10R Asphalt and Pertamina Asphalt
penetration 60/70 as asphalt control, with variations on the same asphalt content
of each type of asphalt, as much as 6 levels of variation asphalt is 6%, 6.5%, 7%,
7.5% and 8%. Testing was done by Marshall standard, Marshall Immersion Test
and Indirect tensile strength test (ITS).
Optimum bitumen content of asphalt mixtures SMA with BNA Blend
75:25:10R is 7.6% while for asphalt pertamina penetration 60/70 is 7%. The use
of asphalt BNA Blend 75:25:10R at SMA mixture causes the value of density,
VMA, VFWA, IKS, stability and MQ are higher than pertamina asphalt AC
60/70, while for VITM and flow are lower than asphalt pertamina AC 60/70. And
the value of the resulting Tensile Strength Ratio (TSR) BNA Blend 75:25:10R
asphalt is 83.8397% lower than asphalt pertamina AC 60/70 that is 86.1347%.
