Influence of Different Aging State on the Performance of Asphalt Mixtures at Low-Temperature

The Indirect Tensile Test was used to evaluate the performance of asphalt mixtures at low-temperature under different aging states.Through the comparison of the results from original asphalt mixtures,STOA asphalt mixtures and LTOA asphalt mixtures,tests show that the original asphalt mixture can not reflect the real performance of the asphalt mixture in the spot.And the short-term aging specimens are more sensitive than long-term aging specimens in appraising the performance of the asphalt mixture at low-temperature.The results indicate that the consideration of aging during the asphalt mixture performance evaluations is necessary.
