Abstract: Recycling asphalt pavement creates a cycle of reusing materials that optimizes the use of natural resources. Reclaimed asphalt pavement (RAP) is a useful alternative to virgin materials because it reduces the need to use virgin aggregate.[1] In this investigation, it has been studied the effect of nano material such as nano silica and nano carbon on the mechanical properties of marshall specimen. Tests were carried out on cold RAP with slow setting emulsion. Optimum percent of emulsion was obtained from previous research. After determination the optimum percent of nano silica and nano carbon tubes , these percent used with optimum percent of latex to studding the improvement in mechanical properties. The results showed that, there is improvement in stability about 150% by used nano materials.
