Bridge decks and overlays operate under repeated traffic, vibration, weather exposure, shrinkage, and surface abrasion. Once cracks form, water and chlorides can enter the concrete and accelerate deterioration. That is why crack control and low permeability are critical in bridge rehabilitation and overlay systems.
Glassman AR Glass Fibres by DD Solutions help reinforce overlays from within by controlling micro-cracks, improving surface integrity, reducing permeability, and supporting long-term durability.
For repair and resurfacing projects, Glassman fibres help create tougher, cleaner, and more durable overlay systems.
Bridges & Overlays?
Overlays are often thin, exposed, and heavily stressed. That means cracks must be controlled early. Glassman AR Glass Fibres help reinforce the overlay matrix throughout its full depth, improving crack control and surface performance without adding corrosion risk.
For bridge and repair projects, this is especially valuable because the goal is not only to repair the surface it is to extend the life of the structure.
Key Benefits
Typical Applications
- Overpass repair works
- Concrete repair toppings
- Industrial traffic overlays
- Parking deck resurfacing
- Bridge deck overlays
- Flyover resurfacing
- Overpass repair works
Usage & Mixing Guildlines
- Add Glassman fibres during final mixing
- Ensure uniform dispersion before placement
- Prepare and clean the existing surface before overlay application
- Use bonding systems as specified by project design
- Conduct trial mixes for thin overlays and repair toppings
Quality Standards
- Crack-control performance review
- Permeability and durability assessment
- ASTM C1116/C1116M recognizes glass fibre-reinforced concrete as Type II fibre-reinforced concrete containing alkali-resistant glass fibres.
Recommended Fibre Types
Glassman AR Glass Fibre – 12mm
Recommended for overlays, repair toppings, and bridge deck resurfacing.
Glassman AR Glass Fibre – 16mm
Suitable for thicker overlays or higher crack-control requirements, subject to trial mix.
Suggested Dosage
0.5 kg to 1.0 kg per m³ of concrete
Final dosage should be based on overlay thickness, traffic exposure, crack-control requirements, bonding system, and approved mix design.
Technical Note
Recommended dosage and fibre length should always be finalized based on the application, mix design, site conditions, and trial results.
For structural replacement of steel reinforcement, project-specific validation by a qualified engineer is required.
