A composition of improved self-tack is based on an amorphous terpolymer of ethylene propylene or butene-1, and a diene or triene, and contains per 100 parts by weight of terpolymer, bitumen, a bitumen-containing petroleum distillate or bitumen-containing distillation residue in an amount of 2 to 100 parts by weight. In the examples, the compositions are based on ethylene-propylene-1,4-hexadiene copolymer and additionally contain ISAF black, zinc oxide, and naphthenic mineral oil.
