Nanoscale viscoelastic characterization of asphalt binders using the AFM-nDMA test

This paper portrays the first set of results of nanoscale viscoelastic (VE) properties of asphalt binders obtained using the recently developed Atomic Force Microscopy-Nanoscale Dynamic Mechanical Analysis (AFM-nDMA) testing mode. To this end, nanoscale frequency sweeps were carried out on eight different asphalt samples including an unmodified asphalt binder and seven Low-Density Polyethylene (LDPE) modified binders. The nDMA testing mode was...
