Increased traffic on the roads and need to increase the resistance of asphalt mixtures. One of the methods to increase the strength is mixtures with sulfur compounds. Googas is a compound of sulfur and some polymers that can be used as potential asphalt modifier . In this research evaluated bas mixtures and combination of Googas and bitumen, whilst decreases both the costs of asphalt mixture and dangerous sulfuric vapors, increased Marshall resistance on Googas modified mixtures compared with unmodified mixtures. Generally Googas samples showed higher dynamic modulus at the same temp and freq. Googas specimens has mor flow time than base specimen in static creep test. Dynamic creep test results show that the sample contains Googas has more flow number than the unmodified mixtures. Fatigue test results showed that the samples containing Googas has mor fatigue life than the unmodified samples. Wheel track test results showed that Googas modified mixtures has lower rut depth than the unmodified mixtures.
