Primary Function
Heavy-duty asphalt reinforcement & joint crack control
Some pavement problems are not “general cracking”—they are concentrated stress conditions: joints telegraphing through overlays, transitions between rigid and flexible structures, bridge approaches, localised deformation, and repetitive turning/braking at intersections. GGA 200 SA – Self-Adhesive Glass Geogrid Asphalt Reinforcement is designed specifically for these higher-risk reinforcement zones.
GGA 200 SA uses a self-adhesive glass fibre geogrid with a tighter aperture configuration and asymmetric tensile strength (higher capacity in the principal direction). This makes it a practical specification choice for applications where stress is directional or where reinforcement requirements exceed standard 50/50 or 100/100 grid classes.
Installed as an asphalt interlayer, GGA 200 SA functions by intercepting tensile stresses within the asphalt and spreading them laterally. This reduces crack opening, delays crack reflection, and improves fatigue performance—especially across joints and discontinuities. The self-adhesive coating provides placement stability during construction, helping installers maintain alignment and overlap control in high-production environments.
Talk to us if your applications require heavy duty asphalt reinforcement geogrid, self adhesive glass grid for joints, bridge approach crack control, pavement joint reinforcement, reflective crack control at transitions, and 100/200 glass geogrid.
Where GGA 200 SA is typically specified
Reinforcing overlays over rigid pavement joints
Bridge approaches and transition zones
Localised severe cracking areas before resurfacing
Intersections, roundabouts, and braking zones
Repairs where reinforcement must be stronger in one direction
Why the tighter grid matters
The smaller aperture is commonly chosen where cracks are closely spaced or where reinforcement needs to engage the asphalt more frequently. Combined with high tensile capacity, it supports performance in demanding reinforcement zones.
Installation principles
As with all asphalt interlayers, good outcomes require correct substrate preparation, tack coat practice, smooth placement, and proper rolling/compaction controls. Any reinforcement grid can be compromised by contamination or poor bonding—so quality installation is part of the specification intent.
If your project includes joints, transitions, or severe cracking, and you want a heavy-duty reinforcement class with clear specification identity, GGA 200 SA is the correct product to list and to price.
