In order to compare and evaluate the dynamic modulus of aged asphalt mixture obtained in room and field pavement, the asphalt mixture specimens were prepared according to the materials of upper, middle and lower layers of the fifth ring road in Beijing. Indirect tensile dynamic modulus tests were carried out under different aging degrees. Based on the time temperature equivalence principle, the dynamic modulus master curves of specimens under different aging degrees were established and compared with the field core specimens. Results show that the effect of aging on the dynamic modulus of asphalt mixtures gradually increased with the increase of temperature. The comparative analysis of the dynamic modulus of the three asphalt mixtures with different aging degrees indicates that the sensitivity of the dynamic modulus of asphalt mixtures to the aging effect is AC 25>AC 30>SMA 16 in turn. There is not much difference between indoor and outdoor aging asphalt mixture dynamic modulus master curves in the indirect tensile dynamic modulus test, pavement asphalt mixture dynamic modulus can be evaluated by laboratory test.
