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 1):
A method for bonding a hot mix asphalt layer to a substrate pavement layer comprising:\n (a) heating a non-aqueous tack coat composition to a temperature above its softening point until it is liquid, said non-aqueous tack coat composition comprising a low pen petroleum based asphalt ingredient, said 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., which 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 ambient temperatures and having a pen value less than 30 dmm at 25\u00b0 C.; and (c) applying a heated hot mix asphalt layer on top of said non-aqueous tack coat layer.
