Abstract

In this research, the viscoelastic properties and microstructure of asphalt binders modified with two Crumb rubber modifiers (CRM), #50 and #30, using mechanical tests and Atomic force microscopy (AFM) were evaluated. Each modified asphalt binder was prepared by mixing 5% and 15% CRM. The Separation index (SI) of each binder was calculated using rheological measurements (G*/sin δ and % recovery). Additionally, AFM was employed to capture topographical images of the CRM asphalt binders, aiding in a comprehensive assessment for SI. The key findings include (1) enhanced rheological properties in the lower sections of CRM asphalt binders, attributed to density differences between the CRM and the base asphalt; (2) lower SI in #50 CRM binders, correlating with their more uniform particle distribution; and (3) microstructural distinctions observed via AFM, with #50 CRM binders showing uniformity across top and bottom layers, unlike #30 CRM binders. These insights demonstrate that microstructural images can be an effective tool for assessing the storage stability of CRM asphalt binders, thereby contributing significantly to a more in-depth understanding of their stability.
