Full or Partial Replacement of Bitumen in Mix Design by the Use of Bio- Asphalt

Malik Wiqqas Javaid , Er. Brahamjeet Singh

The experimental program of this research has been designed to characterize the different bio-oils and to study the applicability of developing bio-binders from them to be used in the pavement industry. With the advent of new technologies, the use of bio asphalt in mix design or recycled asphalt pavement material has gained increasing importance. Using it is not only increasing the economic value of Asphalt production, but also decreases the demand of virgin materials. The limit in the use of bio asphalt proportion is restricted due to stiffness and workability issues. This problem is addressed with the help of warm mix bio asphalt producing mixes having the same properties, better workability, and minimizes the property of viscosity than hot mix asphalt at lower temperatures.
