Exceedingly heavy axle loads on the highways can lead to permanent deformation. Rutting of hot rolled asphalt mixture can be predicted by laboratory creep test. The purpose of this paper is to look at some aspects of the effects of fine aggregate properties on the creep behavior of HMA mixture. Two types of sand (quarry and mining sand) with two conventional binder (50/60 and 80/100pen) and four PMB namely PM1 PG 82 and 76 and PM2 PG 82 and 76 were used. According to the dynamic creep test results, quarry sand that has more angularity, rougher, higher shear strength and a higher percentage of Aluminum oxide presented higher resistance to creep. Also PMB mixture gives better creep results than conventional mixture.
