Keeping in mind the growing need for innovative solutions to reduce road repair costs, Saint-Gobain India ADFORS offers reinforcing composite GlasGrid for enhancing the service life of bituminous roads.
Over the past 40+ years, Composite Glass Fiber Reinforcement Grid has been the most successful in mitigating the growth of thermal and stress-related reflection cracks that may come to the surface of new bituminous overlay. The product has been used extensively in highway, runway construction and maintenance work in more than 64 countries, with nearly 3500 projects occurring yearly.
Composite GlasGrid can increase the service life of bituminous roads significantly by integrating with various applications such as:
- Periodic road repairs and maintenance
- Road resurfacing/rehabilitation projects – deep milling and 40 mm thick bituminous overlay projects.
- Cement-treated base pavements (CTB)
- Full depth reclamation pavements (FDR)
- Greenfield construction
- Bituminous overlay on cement concrete road
This technology arrests the reflection cracks in new bituminous overlays by acting as a stress-absorbing membrane interlayer. This technology can be a sustainable and economical solution for most rehabilitation projects in India.
Using Saint-Gobain Adfors composite GlasGrid has led to:
- Reduction in frequent maintenance activity.
- Better performance in terms of fatigue damage, reflection cracking resistance and rutting of bituminous roads.
- Sustainable option.
- Lesser consumption of natural resources like aggregates.
- Recyclable in nature
The four-point bending fatigue tests carried out by the Indian Institute of Technology Madras (IITM) on Saint-Gobain India ADFORS GlasGrid show that the fatigue life of bituminous mixtures reinforced with the same is at least three times higher compared to unreinforced bituminous mixtures.
