Abstract: | The utilization of crumb rubber and reclaimed asphalt pavement (RAP) has proven to be economical, environmentally sound, and effective in increasing the performance properties of the asphalt mixtures. In this research study the RAP content was varied from 0–60% (0%, 20%, 40%, and 60%) and crumb-rubber additive (0%, 10%, and 15% by weigh of bitumen) was blended with the unmodified binder by using wet process. The rutting performance of these modified asphalt mixtures were investigated. The results of the experiments indicated that the use of RAP and crumb rubber in HMA can effectively improve the engineering properties of these mixes. |
