Research on nano asphalt offers a promising prospect because it can
significantly enhance the performance of asphalts at both low and
high temperature. Nanoparticles are the key materials that can improve
mechanical and physical properties also durability in road pavement. It has
been reported that adding of nanomaterials such as nanosilica, nano calcium
carbonate, nanotubes, and nanoclay in asphalts mixture will increase the
viscosity of asphalt binders and improves the rutting and fatigue resistance
of asphalt mixtures. Several attempts have been conducted to make nano
asphalt i.e. by mixing mineral nanoparticles or oxides into the asphalt.
However, this method has some disadvantages such as the tendency of the
nanoparticles to agglomerate and the difficulty to distribute them evenly in
the asphalt mixture because of the high viscosity of asphalt. Also, the price
of those nanoparticles is still expensive. In this work, we are using a facile
and economical method to produce nano asphalt. The nanoparticles are
produced directly during the process from the natural asphalt in the Asbuton
rocks which are found in Buton Island (Indonesia). The nanoparticles are
produced and mixed evenly in the system by combining the microemulsion
method and ultrasonication. Therefore, it is not necessary to purchase the
expensive nanoparticles for making nano asphalt. The influence parameters
such as the concentration and kind of solvent, concentration and kind of
surfactant, and mixing temperature were studied. The little amount of both
solvent and surfactant that are used in this method (less than 5%) with the
high yield of each variation (around 99%), make this process worth to be
developed and applied in the road pavement.
