Abstract

Abstract

Nanotechnology is an engineering technology on materials into atomic or molecular sizes. One of the unique properties of nanomaterials is that have a large surface fraction and high surface performance. This study aims to determine the effect of the addition of nanomaterials on hot mix asphalt (AC-WC). The nano material used is silica from Bangka Belitung quartz sand which is processed into nano silica by Balai Besar Keramik Bandung. The asphalt used in the mixture is asphalt pen 60/70 produced by Pertamina. Nano silica is used as a filler substitution so that is can reduce the asphalt content which could be seen from the optimum asphalt content value with mixed variations of 1%, 2%, 3% nano silica when compared to conventional asphalt mixtures. In addition, using different compactor has an effect on nano silika mixture asphalt density. It can be seen that density value from superpave gyratori compactor (SGC) is lower than marshall compactor. In addition, the difference in the compaction method also affects the number of void in mixture and specimen height.

Keyword: Asphalt mixture, asphalt content, filler, nanosilica.
