Use of nano-materials to enhance the properties of asphalt mixes

Abstract

Nanotechnology is being used in different aspects of life to solve different problems. Highway researchers and practitioner are also using nano-materials to modify asphalt binders. Studies associated with the use of nano-materials in pavement construction are still very limited. In order to make this more applicable in the field, there is a need of more studies on this topic. The current study investigates the influence of the nano-based chemical warm mix additive zycotherm on the characteristics of asphalt mixes. In the study zycotherm was added into the mix in different proportions and the properties of the asphalt mixes were examined. In order to assess the moisture damage resistance of the mix, parameters like retained marshall stability (RMS) and tensile strength ratio (TSR) were calculated. Based on the results of these tests, comparisons are made and conclusions are presented in this paper.
