Abstract
Homogeneous thermoplastic bituminous compositions containing up to 25 parts by weight of ethylene-.alpha.-olefin rubber, e.g. ethylene-propylene rubber, saturated or unsaturated, exhibit improved properties for all asphalt applications, e.g. pipe coating, roads, roofing, etc. The compositions are produced by heating and agitating the bitumen and rubber at above 170.degree. C., preferably 180.degree.-240.degree. C., or by subjecting the rubber to premastication before admixture with the bitumen at lower temperatures. Cross-linkable rubbers can be cross-linked in the bituminous compositions to yield high tensile strength final products.
