GlasGrid Reinforcement System
The GlasGrid® Asphalt Reinforcement System is composed of fiberglass strands coated with an elastomeric polymer and formed into a grid structure. Each strand has a remarkably high tensile strength and high modulus of elasticity; this is particularly important as asphalt concrete typically cracks at low strains.
When the GlasGrid System is sandwiched between the leveling course and the surface course in an asphalt overlay, it becomes the hidden strength in the road, turning vertical crack stresses horizontally to effectively dissipate them.
Easily Installed, Durable in Any ClimateThe GlasGrid System can be easily installed without specialized equipment or labor.
Fully Millable and RecyclableUnlike 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).
Smooth Landings on Airport PavementsThe GlasGrid System has been successfully used on more than 100 airport projects, including full width and spot repairs, for more than two decades.
Lower Cost PavementsWhen overall life cycle costs are considered, the GlasGrid System can save up to 30% on the total cost of a pavement rehabilitation.
Thinner PavementsAirport overlays reinforced with the GlasGrid System retard reflective cracking as well as an unreinforced overlay up to twice as thick.
Extension of Pavement LifeReduced maintenance, with longer maintenance intervals.
GlasGrid® TF (Tack Film)
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.
Mirafi® MPG100 is the solution for pavement engineers. Asphalt reinforcement by high-modulus glass filaments, combined with the sealing and uniform bonding effect of the nonwoven geotextile, provides effective maintenance and prolongs the working life of road structure.
Mirafi® MPG100 composite is a reinforced paving interlayer with high strength, low elongation and high asphalt absorption. When installed with sufficient asphalt cement tack coat on a properly prepared surface, Mirafi® MPG composite and the tack coat form an impermeable interlayer system that is fully recyclable and adds long-term lifecycle cost benefits to your pavement.

Mirafi® MPG4 is a composite paving interlayer comprised of a lightweight polypropylene paving fabric reinforced with continuous filament fiberglass, mechanically fastened in the machine, cross and bias angle directions. This unique, patent pending paving interlayer is designed for highly distressed pavement conditions and in addition, the material will provide a moisture barrier against further moisture intrusion. The lightweight polypropylene fabric requires less asphalt tack, saving on installation costs without compromising performance
