ABSTRACT:
A pressure sensitive bituminous composition having improved tack and adhesiveness, comprising: (1) from about 50% to about 87% of a bituminous component; from about 1 to about 15% of a thermoplastic block copolymer, M.sub.1, of the A-B-A type, preferably styrene-butadiene-styrene; (3) from about 1% to about 10% of a block copolymer, M.sub.2, of the A-B type, preferably styrene-butadiene; and (4) from about 5% to about 50% of a fumed silica. The fumed silica is an active ingredient which absorbs excess oil and improves the tack and adhesiveness of the final composition.
