Effect of Irradiated Crumb Rubber on Cold Recycled Bitumen Emulsion Mixes Properties

Recycling is one of the most innovative and interesting techniques for the rehabilitation of distressed road pavements. In recent years the increased interest in this process has led to the development of various alternative methods for the recovery and the reuse of road bituminous materials. Cold recycling is among the recycling techniques. Many researches involve the use of Crumb Rubber within a mixture containing 100% Reclaimed Asphalt Pavement. The goal of this research is to analyze and evaluate the different physical and mechanical characteristics from addition of irradiated crumb rubber to asphalt emulsion cold mixes. The results indicated that the existence of the irradiated crumb in asphalt emulsion could improve the indirect tensile strength, high temperature stability, moisture resistance and fatigue performance of asphalt emulsion cold recycled mixes
