Abstract
A composite tack film is provided. The composite tack film includes a) a first polymer layer including a thermally conductive polymer having a melting temperature of less than about 100° C.; b) a second polymer layer adjacent the first polymer layer, the second polymer layer including a visco-elastic, thermally conductive polymer having a melting temperature of less than about 110° C.; and c) a third polymer layer adjacent the second polymer layer, the third polymer layer including a thermally insulative polymer having a melting temperature of less than about 100° C. Further included is a method of reinforcing pavement with the aforementioned composite tack film.
