A bituminous composition is used as an adhesive binder. The bituminous composition has at least one acidic additive of general formula (I): R(COOH)z in which R is a linear or branched, saturated or unsaturated hydrocarbon-based chain having from 4 to 68 carbon atoms, preferably from 4 to 54 carbon atoms, more preferentially from 4 to 36 carbon atoms and z is an integer ranging from 1 to 4, preferably from 2 to 4.

A sealant pouch system for adhering roofing shingles includes a plurality of pouches containing an adhesive with a viscosity of 25 cps to 2500 cps. Each pouch comprises an outer film that encases the adhesive and is configured to rupture when subjected to a sufficient force or a temperature above a predetermined threshold. The method of installation involves placing the pouches on the reveal portion of shingles in a first row, installing a second row of shingles to overlap the first row, and applying sufficient force to rupture the pouches, causing the adhesive to contact both the headlap and reveal portions of the shingles, thereby sealing the rows together. The pouches may have various shapes and are designed to prevent rolling or sliding off sloped roof decks.

A sealant composition for roofing shingles that includes a base asphalt, a linear and/or a radial copolymer, oil, and a wax is provided. The linear copolymer has an A-B di-block or an A-B-A tri-block structure. The radial copolymer may have an (A-B).sub.n radial structure, where n is at least 4, or a tri-block (A-B-A) radial structure having from 4 to 8 arms. Blocks A and B may individually represent (1) styrene and butadiene or (2) styrene and isoprene. The oil is a petroleum-based oil that both softens the asphalt and reduces the viscosity of the sealant composition. The wax may be a bis-stearamide wax. Additionally, the sealant composition may be reacted with elemental sulfur to crosslink the copolymer blend. The sealant composition seals at temperatures lower than conventional sealants and promotes the easy release of the shingle from a shingle bundle.
