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 3):
A method of constructing a multiple layer pavement structure comprising:\n (a) applying a liquefied non-aqueous tack coat layer to a substrate pavement layer, said non- aqueous tack coat layer being non-adhesive at ambient temperatures and adhesive when heated to temperatures exceeding 212\u00b0 F. and having a pen value of less than 30 dmm at 25\u00b0 C., said non-aqueous tack coat layer comprising a mixture of an asphalt ingredient and at least one additive ingredient, the 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.; (b) allowing said non-aqueous tack coat layer to cool below its softening point; and (c) applying an asphalt layer on top of said non-aqueous tack coat layer that has cooled, said asphalt layer heated to a temperature sufficient to liquefy said non-aqueous tack coat layer that has cooled.
