For over a century, paved roadways have been constructed using asphalt concrete mixes across the world. This research was aimed on evaluation of the effect of the waste rubber tire modified bitumen on Asphalt performance, to investigate physical properties such as the stability and flow. Marshall Stability Method was used to determine the Optimum Binder Content (OBC) and to evaluate the properties of the crumb rubber. Five different percentage of rubber by weight of bitumen: 0%, 5%, 10%, 15%, 20% were used. A comparative study is made among the unmodified and modified bitumen samples using the various sizes of waste rubber tire bitumen particles and the modified. The results of the study revealed that as rubber content increase from 0 to 20% penetration decreased from 68.5 to 58.5 mm. Similarly, for the same percentage increase in rubber content ductility decrease from 100 to 75 cm. Asphalt mixes with crumb rubber 15% have higher stability, it is two times more than the minimum specification and lower marshal flow. From this study it is concluded that recycled crumb rubber can therefore be beneficial to the performance of the asphalt concrete pavements as well as provide a means of safe disposal of these non-biodegradable wastes.
