Abstract

The objective of this study is to review existing literature in the area of Nano-modification of asphalt and proceed to apply Nano-materials to asphalt to improve the performance. This study integrates literature review, preparation and characterization of Nano-modified asphalt materials. This study including aggregate tests to prove that these aggregate accepted to use it in asphalt binder, and tests of used bitumen samples. In this study the experimental testing three types of Nano clay (A, B, C) at 2% and 4% by the weight of asphalt were blended in asphalt binder at high temperature to exfoliate the Nano clay within the asphalt. The asphalt binder was then characterized using the AASHTO viscosity, penetration test, softening point, flash point and Marshall Test. These types of additives of Nano-clay are increasing the viscosity by increasing the percent of Nano clay and decreasing the penetration by increasing the percent of Nano clay but not affected with softening point and flash point. About Marshall Stability there are many changes: In case of adding Nano clay (A-2%) Marshall Stabilization decrease; although it increased again when adding Nano clay (A-4%) but not reached to the original sample stabilization. In case of adding Nano clay (B-2% and 4%) it still increase. In case of adding Nano clay (C-2%) it increased; although when adding Nano clay (C-4%) it decreases again (bell shape).
