Abstract

Polyethylene-modified bitumens having improved compactibility. Polyethylene-modified bitumens consisting of a bitumen obtained from crudes having API grades between 29 and 44, a polyethylene or mixtures of polyethylene in a percentage of between 0.5% and 49% with between 0 and 8% of an ethylene or ethylene-propylene polymer which improves the compactibility of the bitumen and polyethylene and between 0 and some 4% of a system which anchors the ethylene or ethylene-propylene polymer to the bitumen are described. Using a Cole-Cole diagram it is shown that these bitumens have improved compactibility in comparison with other polyethylene-modified bitumens.
