Paving composite and method of paving

Abstract

A tack film material comprises a carrier substrate comprising a polymer film having first and second major surfaces. A surface layer on the first and second major surfaces comprises a resinous non-asphaltic material or a material including about 50% or more resinous non-asphaltic component and about 50% of less of asphaltic component. the surface layer is capable of forming a bond with an adjacent layer of asphaltic paving material, when the surface layer is heated to a temperature of about 120° C. or more under a pressure that is applied to the tack film material by an overlying layer of the asphaltic paving material having a thickness of about 3.8 cm (1.5 inch) or more laid. The surface layer is not tacky at a temperature of about 20° C. and a pressure of about one atmosphere.
