Effects of Wax-Based Surfactant on the Quantification of Chemical Properties, Rheological, and Activation Energy of Cup Lump Rubber Modified Asphalt Binder

Key Points

• This research aims to evaluate how a wax-based surfactant influences the chemical, rheological, and activation energy properties of asphalt binder modified with cup lump rubber.
• Experimental design assessing chemical properties of modified asphalt
• Rheological tests for viscosity and deformation characteristics
• Activation energy measurement for material performance under stress
• The wax-based surfactant significantly enhances the rheological properties of the modified asphalt binder.
• Improved activation energy indicates better performance under varying traffic loads.
• Overall durability of the asphalt binder is increased in tropical climates.
