Abstract
An asphalt base pressure-sensitive adhesive includes asphalt, an elastomer, residual pitch, as well as isoflour and optional oil and other inert fillers. The amount of elastomer is reduced by incorporating the residual pitch product which acts as an extender of the elastomer. Further, the isoflour further acts as an extender, and is compatible with the residual pitch. In a preferred embodiment, the pitch product is pine pitch.
