Abstract

The invention provides a polymer- modified bitumen comprising Venezualan feed stock bitumen and tetrachain radial teleblock polybutadiene/ polystyrene copolymer of at least 100,000 molecular weight. The components can be readily blended to increase the softening point of the bitumen without undue increase in melt viscosity to give a product of good low temperature flexibility. The proportion of co-polymer, based on the total polymer/bitumen mix, is suitably 10-14 weight %. The copolymers of higher molecular weight, e.g. 180,000, give the best increase in softening point and low temperature flexibility, but for ready blending in the bitumen may need to be fluxed with lube oil also from Venezualan feed stock. The modified bitumen, which can be in admixture with conventional fillers and additives, can be provided as a calendered sheet, or as a coating bitumen or an expansion joint compound.
