ADFORS GlasGrid GG Full Lane Width Pavement Reinforcement System is manufactured at a Saint-Gobain ADFORS facility that has achieved ISO 9001:2015 certification and meets the requirements of EN 15381. ADFORS GlasGrid is a high strength, open fiberglass grid custom knitted in a stable construction and coated with a patented elastomeric polymer and self-adhesive glue. Every component of the matrix shall be stabilized against ultraviolet degradation and inert to chemicals normally found in a natural soil environment. ADFORS GlasGrid conforms to the property values listed below, which have been derived from quality conformance testing performed by an accredited laboratory:
ADFORS GlasGrid product line offers several styles of pavement reinforcement grids designed to reinforce asphalt concrete overlays. They retard reflective cracking by a factor of 2 to 3 times by turning stresses horizontally in order to dissipate them.
The grid configuration features fiberglass strands coated with an elastomeric polymer. Each strand has a remarkably high tensile strength, as well as a high modulus of elasticity at low elongation – making ADFORS GlasGrid stronger than steel by weight.

SOIL REINFORCEMENT SYSTEM
Tarmaxx Grid ( GEOGRID )
TARMAXX GRID ( GEOGRID ) is a geosynthetic material used to reinforce retaining walls or soil beneath roads. There are two types of TARMAXX GRID ( GEOGRID ) available : biaxial or uniaxial .
Geogrid Reinforcement Mechanism
A subgrade soil beneath a paved or unpaved surface can fail under load in two ways: localized shear failure and bearing capacity failure. Localized shear failure typically occurs in the form of severe deformation or rutting in soft subgrades when loading exceeds the subgrade strength.
Geogrid reinforcement of granular fills over soft soil can prevent localized shear failure of the subgrade and therefore significantly increases the effective bearing capacity of the subgrade .
A geogrid's primary stabilization mechanism is lateral restraint of the aggregate materials through a process of interlocking the aggregate and the apertures of the geogrid.
The level of lateral restraint that is achieved is a function of the type of geogrid and the quality and gradation of the aggregate material placed on the geogrid. To maximize performance of the geogrid, a well-graded granular material should be selected that is sized appropriately for the aperture size of the geogrid.
When aggregate is placed over geogrid, it quickly becomes confined within the apertures and is restrained from punching into the soft subgrade and shoving laterally. This results in a "stiffened" aggregate platform over the TARMAXX geogrid.
