Abstract
An adhesive composition for roofing such as shingles is disclosed which is composed of a hard asphaltic bitumen fraction having a penetration number at 77.degree. F. of from 0 to 30 dmm and a softening point of from about 150.degree. to 220.degree. F. and an elastomeric composition composed of a thermoplastic elastomer and a plasticizer wherein the overall adhesive composition has a penetration number of from 30 to 100 dmm at 130.degree. F. and a softening point of 140.degree. to 230.degree. F. The inventive composition is self-sealing and exhibits excellent squash resistance, low temperature properties and resistance to blowoff. The composition can be used with shingles as well as other types of roofing coverings.
