Density Curves of the Asphalt Models at 333 K during 20 ns All-Atom MD Simulations. It shall be noted that VA is for virgin asphalt, SA is for short-term aged asphalt, and LA is for long-term aged asphalt. The number with the labels indicates the corresponding nano-SiO2 modified asphalt and the size of the number is the radius of the nano-SiO2 particles with the unit of Å
