ABSTRACT:
A pressure-sensitive adhesive is disclosed which is prepared by hot melt blending paving grade asphalt, a depolymerized virgin rubber, a terpene resin, and a vulcanizable, non-depolymerized styrene-butadiene copolymer. These adhesives are especially useful in forming membranes by coating one side of an asphaltic based coated reinforcement with these adhesives. They are useful for highway repair and maintenance purposes and for waterproofing and show good adhesion to cementitious, for example asphaltic concrete or Portland cement concrete, substrates.
