Key statement: The present invention is directed to a process for preparing a polymer modified bituminous binder composition in the substantial absence of crosslinking agents by heating a bitumen component in a stirred tank to a temperature from 160[degrees]C to 221[degrees]C; adding a block copolymer composition to the bitumen component while the bitumen component is being stirred to form a homogeneous mixture of the bitumen component and the block copolymer composition; and continuing to stir the homogeneous mixture while maintaining the temperature from 180[degrees]C to 221[degrees]C for a total period of time from four hours to 30 hours, thereby forming a cured polymer modified bituminous binder composition.
On the other hand, two immiscible constituents can be chemically linked together to form a block copolymer with fine uniform microdomains of several tens of nanometers, which is explicitly smaller than the domain size in polymer blends (usually in the order of 1 [micro]m).
