Abstract

Asphalt modification with nanotechnology materials can be in the form of nanoclay, carbon nanotubes and nanosilica. Recent research found that nanosilica has been proven to improve rutting performance and fatigue resistance in asphalt mixtures. Nanosilica that will be used in this research is nanosilica from Lapindo hot mud, Sidoarjo. One effort to reduce the impact of losses is to use Lapindo mud that has a large enough potential to be used as a source of silica in Indonesia. With the advancement of nanotechnology that already exists and proving that nanosilica can increase the performance of asphalt, this research on the characteristics of pen 60 modified asphalt nanosilica will be conducted with a percentage of 2%, 4%, 6%, and 8%. The research was based on laboratory works. The modified asphalt showed increasing 40,35% in penetration, 112,3% in penetration index and 13,586% in viscosity, 39,96% in flashpoint, and 2,9% specific gravity. The increasing characteristic also indicates that asphalt would be more resistant to rutting and fatigue. From the results of laboratory testing, the NaCl content affects the characteristics of asphalt more than the silica contained in Lapindo mud extraction. Because of the NaCl, asphalt modified indicates the lack of pavement resistance to rutting.
