Abstract
Nanomaterials, due to their higher surface area, smaller particle size, and unique chemical characteristics, might be a potential additive to self-heal microcracks in asphalt pavement and extend pavement life. The goal of this study is to examine the self-healing potential of asphalt binder modified with nanosilica, nanoalumina, and nanoclay at three different dosages. First, factors affecting self-healing behavior (i.e., blending techniques, rest period, and damage level) were investigated following Performance grade, Surface Free Energy, Storage stability, and Fourier Transform Infrared Spectroscopy tests. 1% nanosilica exhibited the highest self-healing potential, while 3% nanoalumina also performed well at higher damage levels.
