Fig. 18From: Atomistic-scale investigation of self-healing mechanism in Nano-silica modified asphalt through molecular dynamics simulationComparison of the Molecular Diffusion Coefficient of the Components in the Asphalt Models at 333 K: (a) VA, VA-6.5, and VA-7.5, (b) VA, SA, and LA, and (c) VA-7.5, SA-7.5, and LA-7.5. It shall be noted that As is for asphaltene, Re is for resin, Ar is for aromatic, Sa is for saturate, and NS is for nano-SiO2Back to article page
