In view of the current situation that the evaluation and detection methods of matrix asphalt at home and abroad are mostly macroscopic properties and rarely involve the microstructure of asphalt materials,the petroleum asphalt produced by the three companies was used as the research sample,and the infrared spectroscopy analysis(IR)and Origin peak fitting operation were used as the main analysis methods,supple-mented by nuclear magnetic resonance(NMR)and elemental analysis(EA),and the molecular structure of the research samples was analyzed in detail,and the relevant laws were obtained from them,which provided a basis for effectively distinguishing asphalt origins and identifying asphalt quality.
