Abstract

Permanent deformation (rutting) continue to be the main challenges in improving the performance of bituminous mixture pavements. The purpose of this paper is to look at some aspects of the effects of fine aggregate properties on the rutting behavior of hot mix asphalt. Two types of sand (quarry and mining sand) with two conventional bitumens (PEN 50/60 & PEN 80/100) and four polymer modified bitumens PMB (PM1_82, PM1_76, PM2_82 and PM2_76) were used. Physical, chemical and mechanical tests were performed on the sands to determine their effect when incorporated with a bituminous mixture. According to the wheel tracking results, quarry sand that has more angularity, rougher, higher shear strength and a higher percentage of Aluminum oxide presented higher resistance to rutting. Also a PMB mixture gives better rutting results than conventional mixtures, this is due to the PMB having better viscosity property than that of the conventional bitumen.
