the internal structure of a molecule can be presented in terms of intra-molecular (i.e., inter atomic)and inter-molecular energies such as van der waals, bond and bending, torsion, and inversion energy.in this study, changes in molecular energies of individual asphalt components are evaluated as afunction of physical aging factors. the factors for physical aging such as temperature and pressure...
