[Purposes] The paper aims to analyze the low-temperature performance of seven kinds of fine grained modified asphalt mixture for upper surface layer used in the full-scale pavement test track. [Methods] Three kinds of laboratory experimental research and correlation analysis were carried out, including low-temperature bending test with small beam, linear shrinkage coefficient test with middle beam, and dynamic modulus test with French trapezoidal beam. Then the dimensionless normalized weighted summation method of multi-index test results was used for comprehensive comparative evaluation. [Findings] The maximum flexural strain, strain energy density, linear shrinkage coefficient, complex modulus and phase angle can be used as the reasonable evaluation indexes for the low-temperature performance of the modified asphalt mixture. For the effect of the type of modified asphalt,Compared with the types of modified asphalt, the mixture prepared by SBS modified asphalt with strong low temperature ductility has the best low-temperature performance, followed by the rubber asphalt mixture, and the addition of anti-rutting agent can enhance the low temperature performance of SBS modified AC type mixture. For the effect of the gradations of mineral aggregate, SMA type has the best low-temperature performance, while the lower the coarse aggregate content of SBS modified AC type, the stronger the low-temperature performance. Porous drainage high-viscosity SBS modified PAC type has excellent viscoelasticity and low-temperature shrinkage performance. [Conclusions] The evaluation results can provide reference for long-term monitoring and comparison of low-temperature performance in the test track asphalt pavement.
