Abstract:
A method of applying building a pavement structure using a polymer modified hot-applied tack coat is disclosed. This polymer modified tack coat is non-adhesive at ambient temperatures, and, thus, also non tracking. The tack is applied while hot, but cools quickly. The subsequent application of hot mix asphalt results in a superior bond between the asphalt layer and the tack layer. It is particularly well suited to bonded friction course applications since it removes the necessity of specialized spray paving machinery and allows the use of conventional asphalt distributors and pavers.

Claim (Index 6):
A method for bonding a layer of asphalt pavement material to a substrate pavement layer comprising:\n (a) heating a non-aqueous tack coat composition to over 212\u00b0 F. until it is liquid, said non-aqueous tack coat composition comprising a low pen petroleum based asphalt ingredient having a pen value of less than about 40 dmm at 25\u00b0 C. and a softening point greater than about 140\u00b0 F., wherein said non-aqueous tack coat composition is sprayable and adhesive when heated to temperatures exceeding 212\u00b0 F.; (b) applying said non-aqueous tack coat composition to the substrate pavement layer to form a tack coat layer, said non- aqueous tack coat composition being non-adhesive at temperatures below said non-aqueous tack coat's softening point, and wherein said non-aqueous tack coat composition has a pen value less than 30 dmm at 25\u00b0 C.; and (c) applying a layer of asphalt pavement material onto said tack coat layer.
