This paper presents the execution and analysis of a comprehensive quantum chemistry pipeline for gathering actionable insight into asphalt aging mechanisms through the study of dibenzothiophene (DBT), a key sulfur-containing compound in asphalt binders. Using advanced quantum algorithms, specifically Variational Quantum Eigensolver (VQE) with k-UpCCGSD and ADAPT-VQE ansatze, we achieved ground state energy calculations with accuracies reaching -864.69 Ha. Our implementation demonstrates quantum advantages in handling strongly correlated electron systems while providing actionable insights for designing oxidation-resistant asphalt formulations. The work also establishes a scalable framework for quantum-enhanced materials design.
