    Purpose: The purpose of the study was to evaluate the effects of molasses based fly ash compound (MEUKB), which was derived chemically as seen in Figure A, on the engineering properties of bitumen and bituminous mixturesTheory and Methods: Rotational viscosity and dynamic shear rheometer tests were used in rheological definition of the modified bitumens. Assessment of MEUKB on bituminous mixture properties were performed through Marshall and Nicholson stripping tests. Results: Viscosity and complex shear modulus were found to be increased by MEUKB doping. Marshall stability and stripping resistance of the bituminous mixtures were increased 10.6 % and 85-90 %, respectively.Conclusion: Roadway pavements manufactured with 3% MEUKB modified bitumen will show greater resistance to deformation type distresses, especially rutting, and stripping problems which may occur more often in regions with heavy rainfall.
