The GlasGrid® TF (Tack Film) System provides all the benefits of GlasGrid product, but without the challenges of having to apply a conventional tack coat. With a pre-installed layer of polymer tack film, GlasGrid TF performs like the original GlasGrid System, protecting against reflective cracking while it bonds to asphalt overlays.
Convenient installation is just one of its many benefits. Laboratory beam testing indicates that GlasGrid TF delivers five times the fatigue performance of an unreinforced asphalt section, resulting in longer life for asphalt overlays. With no tack coat emulsion to prepare and apply, owners and installers save on time, labor and material costs, increasing productivity. The elimination of a conventional tack coat also reduces VOC emissions from construction.
The tack film, which requires no curing, inhibits grid movement during paving operations. This enables road construction trucks to drive over the grid with less potential for damage, and it allows immediate installation of hot mix overlays. And like all GlasGrid products, GlasGrid TF is easy to handle and unroll. Installation is simplified with its pressure-activated adhesive, and it’s fully millable and recyclable at the end of its service life.
