Abstract: In order to investigate the role that sulphur additive plays in the asphalt mixture, the four-component analysis was used to examine the change of component of sulphur extended asphalt; Freezing and thawing test, splitting test, rutting test, low temperature bending test were used to find how much the sulphur content affect the performance of asphalt mixture. Test results showed that sulphur could change the group component of asphalt in some conditions, the 25°C penetration and 10°C ductility of asphalt was increased at first and then decreased with the increase of sulphur, and the softening point of asphalt showed monotonically rising with the increase of sulphur;and asphalt could only react with sulphur of a limited content of 15%∼25% of asphalt, and the sulphur over consumption restrictions could not react with asphalt.
