Testing Model Asphalt System Modification Using Molecular Simulation

One original objective of this work was to study a test case of adding a polymer modifier to the model asphalts developed earlier. A second objective was to expand the calculated results from thermodynamics properties, such as density, heat capacity, and compressibility, to transport properties, such as viscosity and modulus. Two additional objectives were recognized as the project began: (1) to repeat the original model asphalt calculations to include properly a parameter that affects planarity of aromatic groups, and (2) to expand mixture compositions to include chemical components of intermediate polarity between naphthene aromatics and asphaltenes, i.e., resin-like compounds. The different chapter in this report will illustrate the progress and success achieved towards each objective.
