This paper carried out the applications of grey system theory to correlate asphalt compositions and heating conditions which consist of asphalt mass, heating temperature and length of heating time. To clarify the influences of the heating conditions, the asphalt compositions were determined, including four generic components, namely asphaltenes, resins, aromatics and saturates, the total contents of asphaltenes and resins replaced by A value, the total contents of aromatics and saturates replaced by B value, and the ratio of A and B(A/B value). Results show that all the four generic components are affected obviously by different conditions and none of the four generic is affected by the largest. The component most affected by asphalt mass is A/B value. In additionally, A value is influenced mainly by the length of heating time while B value by heating temperature.
