GlasGrid® TF System

1 Step Installation (No Tack Coat)

BI -Directional Reinforcement

5X Fatigue Performance of an Unreinforced Asphalt Section

Pre-installed geosynthetic polymer tack film
Ideal for flexible pavement surfaces
Fiberglass strands coated with an elastomeric polymer and formed into a grid structure
High tensile strength and high modulus of elasticity
Fully millable and recyclable after its service life

Conventional tack coats present a variety of challenges, including difficulty achieving uniform coverage, weather-dependent curing time, and keeping it off clean surfaces. 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, the GlasGrid TF system performs even better than the original GlasGrid system, protecting against reflective cracking while it bonds to asphalt overlays.

GlasGrid® is a U.S. registered trademark of Saint-Gobain ADFORS. Other foreign trademarks also apply.

SKUs

The GlasGrid TF system comes in three SKUs: 8501, 8511, and 8512.

Success Stories

Lacey, WA

Convenient Installation

Convenient installation is just one of this system's many benefits. With no tack coat emulsion to prepare and apply, owners and installers increase productivity and save on time, labor, and material costs. The elimination of a conventional tack coat also reduces volatile organic compound (VOC) emissions from construction.

No Curing Required

The tack film requires no curing and inhibits grid movement during paving operations. This enables construction equipment to drive over the grid with less potential for damage, and it allows immediate installation of hot mix overlays.

Fully Millable and Recyclable

Unlike other interlayer systems, the GlasGrid system is easily broken up by conventional milling equipment and reusable in other road projects as recycled asphalt pavement (RAP). Its main component is silica, a natural substance that is environmentally friendly.

A Trusted, Tested Solution

The use of asphalt reinforcement interlayers for preventing reflective cracking has been extensively studied over the last 40 years. Laboratory beam testing indicates that the GlasGrid TF system delivers five times the fatigue performance of an unreinforced asphalt section, resulting in longer life for asphalt overlays.
