A Review on Comparative Study on Bitumen Modification Using Synthetic and Natural Fiber

Transportation sector is showing immense growth in the recent decades, modern vehicles introduced require a more stable platform to run better. In terms of road construction, we are not yet reaching the modernized standards adopted by other countries and usage of modern and innovative road construction materials are yet to be used in transportation infrastructure sector. The available roads are also getting damaged due to improper maintenance of top layer of the road and no bond strength between the bitumen and coarse aggregate. To avoid this kind of cracks and failure of surface bitumen, this is the main binder in the road construction need modification. In this study, there is a comparison between the bitumen modification using synthetic fiber and natural fiber. The bitumen used is the VG-30 which has a penetration value of 50-70 mm. The synthetic fiber used is polypropylene fiber and the natural fiber is the sisal fiber.
