There is a growing need for innovative solutions to reduce road repair costs. Keeping this in mind, 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 to mitigate 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 3,500 projects taking place every year. Composite GlasGrid is one of the distinguished products of Saint-Gobain India Adfors in India. It is utilized in projects like airport runway projects (PPP, Defence & Civil), and road projects (national highways, elevated road projects, state highways), and other related important sectors.

Saint-Gobain-Adfors---GlasGrid 

Composite GlasGrid can increase service life of bituminous roads significantly by integrating with various applications such as:

  • Periodic road repairs & 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 unique 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 in most of the rehabilitation projects in India.

Some of the advantages of Saint-Gobain Adfors composite GlasGrid are:

  • 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

Additionally, the four-point bending fatigue tests carried out on Saint-Gobain India Adfors GlasGrid by Indian Institute of Technology Madras (IITM) shows that the fatigue life of bituminous mixtures reinforced with Saint-Gobain India Adfors GlasGrid is at least three times higher compared to unreinforced bituminous mixtures.

Saint-Gobain India Adfors GlasGrid was installed in accelerated pavement testing facility in IFSTTAR, France. After subjecting the pavement to severe loading condition, Saint-Gobain India Adfors GlasGrid delayed the growth of cracks by minimum 2.4 times compared to unreinforced sections. Several other research studies have been carried out on Saint-Gobain India Adfors product in University of Nottingham (UK), North Carolina State University (USA), EMPA (Switzerland), University of Parma (Italy) to name a few. Saint-Gobain India Adfors is committed to provide a sustainable, environmentally friendly, improved performing solution for road infrastructure in the country.
