PERFORMANCE OF ASPHALT MIXES CONTAINING RUBBER

In the recent years, the rapid growths of population and industrialization levels have been resulted in increased for demand of transportation. In addition, this growth increases the traffic loads which cause several pavement distresses such as rut ting. Several trials were made to control pavement rutting by mix enhancement. These trials w ere already limited pavement rutting, but on the other hand showed pavement cracking as a result of lower flexibility for the modified pavements. This study aims at investigating the effect of crumb rubber on the characteristics of asphalt mixes. T o achieve this objective, crumb rubber with different percentages of fine aggregate (0, 4, 8, 12, 16, 20 , 24 and 28%) were used to manufacture the investigated asphalt mixes.
