During this thesis, many studies and experiments have been done to investigate the effect of adding sulfur polymer to asphalt mixtures. Seven series of samples made using bitumen and sulfur polymer in percentages of 0, 12, 24 and 36% (required bitumen) and in wet and dry mixing conditions were investigated. In this research, various tests were used to eva‎luate the performance of asphalt mixtures in conditions of high temperature, medium temperature, low temperature and moisture sensitivity. Dynamic creep tests, indirect tension, Illinois flexibility index (IFIT) and indirect tensile crack (IDEAL-CT) were used to eva‎luate the performance of the mixtures. The results showed that the addition of sulfur polymer increases the resistance of the mixtures against rutting. But at the same time, this additive can increase the moisture sensitivity of the mixtures and also reduces the cracking resistance of the mixtures. Then, using the method of balanced mixing design (BMD), other samples of asphalt mixtures were prepared and comprehensively investigated. According to the research conducted and the results obtained, this thesis has been carried out in order to comprehensively investigate the effect of adding polymer sulfur to asphalt mixtures using the method of balanced mixing design (BMD).
