Investigation of titanium nanoparticles-reinforced Asphalt Composites Using Rheological Tests

Asphalt binder modification techniques are beneficial for the performance improvement of roads because they can be durable, present less permanent deformation, and provide longer fatigue life. The main agents involved in this process polymers, fillers, fibers, and, more recently, nanomaterials, which have presented technical economic feasibility. nanoparticles were added to base asphalt at a concentration 3% weight pure surface-modified states. This study aims analyze effect surface titanium dioxide using three different agents: oleic acid, benzyl alcohol, oleylamine. results indicated that with oleylamine improved interaction between particles binder, contributing increasing life resistance deformation delaying aging process. Furthermore, rheological tests incorporating into modified 55/75-E 50/70 has produced higher susceptibility cracks.
