The reduction in asphalt mixture production and placement temperatures can be achieved by modifying bitumen 35/50 with the Fischer-Tropsch synthetic wax. To identify the role this modifier plays in the bitumen 35/50, a series of tests has been performed. The experiment was carried out for wax doses from 1.5% to 4.0%. Analysis of the modified binder properties such as ductility at 5, 15 and 25◦C, complex modulus G* with the parameter G*/sinx and LSV, susceptibility according to MSCR procedure, morphology and group type analysis helped describe the structuring function of the F-T wax in the binder. The optimum F-T wax content of 2.5% has been identified to provide the desired parameters required for modified binders.
