Prone to low temperature cracking of asphalt pavement problems in cold areas, testing BBR on 70# base asphalt and 4 kinds of different dosage of SBS modified asphalt, testing TSRST on their mixture to appraisal the low temperature performance of SBS modified asphalt mixture. Results show that compared with the temperature stress of internal cracks of base asphalt and SBS modified asphalt mixture not rise significantly. But the stress of SBS asphalt mixture growing slow and the temperature of cracking reduce obviously; it means the low temperature performance improved. This shows that SBS improves the toughness and reduced the modulus of asphalt mixture in low temperature, rather than increasing the tensile strength of mixture specimens.
