Rheological Properties of Short-Term Aged Foamed Asphalt Modified with Nano Hydrated Lime
This study was initiated with an objective to address the rheological properties of the short-term aged foamed Warm Mix Asphalt (WMA) binders modified with Nano-sized Hydrated Lime (NHL). NHL material was fabricated with two particle sizes of 50 nanometers (nm) and 100nm. Regular Hydrated Lime (RHL) also was used in this study to address the effectiveness of the newly fabricated material, NHL, in comparison to the traditionally used hydrated lime material (i.e., RHL). The Dispersive X-ray Spectroscopy (EDX) technique was employed to study the dispersion and deagglomeration of NHL particles into the admixture. To accomplish the objective of this study, the frequency sweep test - using a Dynamic Shear Rheometer (DSR) machine - was performed to measure the complex shear modulus of short-term aged binders. The overall results reveal that the usage of NHL could be an effective way over RHL to enhance the rheological properties of the asphalt binder.
