Geogrids are integrated within or at the base of unbound layers in flexible pavement systems to enhance the load-bearing capacity and performance of pavements under repeated traffic loads.

Indian Standard IS 17371:2020

IS 17371:2020 specifies the requirements for geogrids used in flexible pavements, focusing on their role in reinforcement and stabilization of base, subbase, and subgrade layers.

• This standard outlines the material properties and specifications necessary for geogrids to function effectively in flexible pavement structures. It serves as a guide for material procurement but does not provide design or construction guidelines.

• The design of geogrid-reinforced flexible pavements should follow standard practices recommended by the Indian Roads Congress using mechanistic-empirical methods, or global practices such as the AASHTO Method, considering parameters related to geogrid interaction with surrounding pavement materials.

• It is important to note that other types of geosynthetics, besides geogrids, may also be used for reinforcement and stabilization of flexible pavements and should be considered as alternative solutions.

By adhering to IS 17371:2020, you ensure that your geogrids meet the essential quality standards for effective reinforcement and stabilization in flexible pavement applications.

Benefits of Securing ISI Mark Certification for Geogrids for Flexible Pavements.

Here are the key benefits of getting ISI Mark certification:

• Government Compliance: The ISI mark confirms that your geogrids meet the stringent quality standards established by the Indian government, ensuring regulatory compliance.

• Mandatory Certification: ISI certification is required for geogrids in flexible pavements. Non-compliance can result in severe penalties, including material seizure and substantial fines.

• Enhanced Market Competitiveness: Certification boosts your product’s marketability by demonstrating adherence to high-quality standards, improving its competitiveness in the market.

• Customer Trust and Preference: ISI certified products are favored by customers due to their assurance of safety and quality. Certification helps you gain the trust and confidence of buyers.

• Market Benchmarking: The ISI mark sets a benchmark for quality, helping to elevate the standard and market value of your geogrids.
