Abstract

Exceedingly heavy axle loads to hot mixture asphalt (HMA) can lead to the permanent deformation. It is caused by repetitive traffic load at high temperature. Rutting of these mixes can be predicted by laboratory creep test. The purpose of this paper is to look at some aspects of the effects of fine aggregate physical, chemical and mechanical properties on the creep behavior of HMA. Four types of sand (quarry, river, mining and marine sand) with two conventional binders (PEN 50/60 & 80/100) and four polymer modified bitumen (PM1_76 & PM1_82 and PM2_76 & PM2_82) were studied on hot mix asphalt creep resistance. According to the dynamic creep test results mixtures prepared using fine aggregate that has more angularity, rougher, high shear strength and high percentage of Al2O3, presented highest resistance to creep deformation. Also polymer modified mixtures give the best result compared with conventional mix.
