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

Abstract

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.
