In order to understand the temperature characteristic of complex modulus,the correlation between the double logarithms of complex modulus and expressions at different temperatures was studied through ten original asphalts produced by two kinds of crude oil as well as these asphalts after RTFOT and PAV.For the first time,through correlation between the slope and intercept of linear fitting correlation,the optimized mathematics formulas between complex modulus and temperature were determined. Mathematics models for different aging stages were established. Mathematics models are simple,accurate,and practical and show universal applicability by comparing measured data at single temperature with predicted data of three asphalts produced by the third crude oil.The data predicted by mathematics model meet the requirements of reproducibility precision of the test method of complex modulus.
