Abstract
Normally incompatible styrenic polymers are stably incorporated into bitumen by using an elastomeric triblock copolymer comprising polystyrene segments which is solubilized or compatibilized in the bituminous phase. The elastomeric triblock copolymer incorporated into the continuous bituminous phase provides polystyrene domains which are dispersed throughout the bitumen or a receiving unit which stabilize the particulate polystyrene against separation from the bitumen.
