Summary: | Nowadays, flexible pavement system still become the choice of transportation Infrastructure. According to that fact, bitumen then become a comodity that is very important to the construction of road. Indonesia is graced by natural resources such as natural asphalt (asbuton) that still exist until many years later. The rheologi characteristic of asbuton has its plus and minus as its function as pavement binder. Its characteristic still in research phase until now. <br />

<br />
Pavement system has main function to bear load and distribute to the subgrade, this behaviour called structural performance of pavement system. <br />

Stone Mastic Asphalt (SMA) asphalt mixture is known as a good structural performance pavement. On this research, SMA used as asphalt mixture bounded with asphalt penetration 60/70 and with adding full bitumen asbuton 3% of total asphalt mix mass. The research using two aggregate gradation with British Standard Spesification. The structural performance of SMA asphalt Mixture with adding 3% asbuton showed better performance compared to SMA asphalt Mixture with no adding of asbuton. For gradation D=5mm, the structural performance showed better to use asbuton 3 % than use no asbuton, although for gradation D=22.4mm, the SMA asphalt Mixture with asbuton 3% does not give any significant change compared to SMA asphalt mixture with no asbuton. But, from four combinations of SMA asphalt mixture, known that adding asbuton 3% to asphalt penetration 60/70 give better and durable asphalt mixture. |
