Date of Original Version



Using molecular simulation to calculate viscosity is useful since it can distinguish among contributions from different compounds in asphalt. In research, equilibrium molecular dynamics simulation was used and both molecular and atomic formalisms were employed to describe stress tensor. The viscosities of some pure and small aromatic compounds were calculated via Green-Kubo expression and correlation functions. Model asphalt mixtures comprising three or more components were studied using atomic and molecular virial formulations of the stress tensor. Viscosity of asphalt mixture having a polymer was analyzed. This is an abstract of a paper presented at the AIChE Annual Meeting (San Francisco, CA 11/12-17/2006).
