Abstarct: Rutting is one of the most common distress of asphalt pavement. This distress occurs due to vertical deformations in the wheel path of vehicles. One of the simple tests to evaluate the performance of asphalt mixtures against rutting is the creep test. The use of different additives in asphalt mixtures in order to improve the rutting performance of these mixtures has been mentioned as a solution in researchers' studies. Crumb rubber and glass powder are among the additives that researchers have used to improve the performance of asphalt mixtures. In this research, crumb rubber with volume percentages of 0.02 and 0.04 has replaced part of fine aggregates and crumb rubber with weight percentages of 4, 7 and 14 as a replacement for part of filler in asphalt mixtures. In order to evaluate the effect of different percentages of additives on the performance of asphalt mixtures, static creep test has been used. Examining the experiments showed that the addition of glass powder increases the rutting resistance. Also, the best performance of asphalt mixtures is related to the addition of 14 percent by weight of glass powder.
