| Abstract | ||||
| Abstract The study was carried out to explore the addition effect of clay, modified clay, rubber, and mixture of both rubber and activated clay on the physical properties of asphalt (60/70). All materials were characterized by SEM. All additives were blended with asphalt in various percentages (starting from 2% to 8%). The blended asphalt were characterized using softening point (°C), and penetration test, and compared with that without additives. There is an increase in the number of pores for both activated clay and rubber compared to that of the non-activated clay. The results of the study indicated an increase in softening point and decrease in penetration. The best improvements in the modified binders were obtained using the mixture of rubber and activated clay. An increase of 28.8% in softening point was obtained by rubber-activated clay mixture. A decrease of24 % in penetration was obtained by rubber-activated clay mixture. The best improvements in the modified binders were obtained at the higher weight percentage of additive. | ||||
