Nanoscale Micromechanical Properties of Allophane-Modified Asphalt Binders Characterized by Peak Force QNM Atomic Force Microscopy
Atomic Force Microscopy (AFM) in Peak Force Quantitative Nanomechanical Mapping (PF-QNM) mode was used to evaluate the micromechanical behavior and morphological evolution of conventional and allophane-modified asphalt under medium-and long-term aging. Topographic analysis revealed the presence of “bee structures” in a...
