Abstract
Nano montmorillonite (MMT) is widely used as a modifier to improve asphalt pavements' performance. This paper's main objective was to investigate the effect of nano-montmorillonite on the self-healing properties of asphalt, which was analysed in terms of energy theory, molecular content composition, and microstructure. The healing index based on time-scan tests was used to characterise the base asphalt and styrene–butadiene–styrene (SBS) asphalt binders. The healing master curve was constructed considering the influence of healing time and damage level, and the composite healing index was calculated. The asphalt binder and aggregate's contact angles were measured using the solid drop method, and thermodynamic parameters were calculated based on surface free energy theory. The effects of MMT on healing properties were investigated by gel permeation chromatography (GPC) and scanning electron microscopy (SEM) in terms of changes in molecular weight composition and microstructure. The results showed that MMT enhanced the asphalt binder's cohesive energy and increased the adhesion energy to the aggregate, which in turn improved the self-healing ability of microcracks. The intercalation structure restricted small molecules' movement and promoted the aggregation of large molecules, thus forming a micron-scale laminar rough structure that enhanced the intermolecular forces and improved the healing ability. In addition, MMT had a more significant healing effect on the base asphalt binder but formed a more stable system with the SBS asphalt binder, giving it better healing potential.
