Title:
A BITUMINOUS MIXTURE COMPRISING POLYURETHANE OBTAINED BY A POLYMERIZATION REACTION OF BHET OBTAINED FROM CHEMICAL DEPOLYMERISATION OF PET WASTE AND A PREPARATION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/009836
Kind Code:
A3
Abstract:
A method for preparing a modified bituminous mixture is developed according to the present invention, this method comprising the steps of fluidizing bitumen as the main component of the mixture at 130-140°C; transferring the fluidized bitumen into a mechanical mixer running at 120 rpm stirring speed; producing a polyurethane-bitumen mixture by adding polyurethane, as an additive in hot form, obtained through a polymerization reaction of BHET monomers obtained through a recycling reaction of waste PET products, as a diol monomer with diisocyanate monomer and a chain extender into bitumen in said mixer while stirring continues; stirring further this mixture for a predetermined time at a predetermined stirring speed to obtain a homogeneous polyurethane-bitumen mixture; following the completion of the stirring process, obtaining a homogeneous polyurethane-added modified bituminous mixture.
