Composition characteristics and evaluation indexes of molecular energy for asphalt components based on principal component analysis

To further explain the molecular behavior of asphalt components, principal component analysis (PCA) was used to study their molecular energy composition characteristics and evaluation indexes. Initially, the molecular models of asphalt components were established, including unaged, short-term aged a...
