BIS CERTIFICATION FOR GEOTEXTILES USED IN SUB-GRADE SEPARATION IN PAVEMENT STRUCTURES IS 16391

Published Date: February 28, 2025 4 min Read

BIS Certification is mandatory for Geotextiles used in sub-grade separation in pavement structures as per IS 16391:2015. This standard ensures that geotextiles meet the required quality, strength, and durability for effective use in pavement construction, especially in soil stabilization and drainage applications. Certification guarantees that the geotextiles undergo stringent testing for properties such as tensile strength, permeability, and long-term durability, ensuring they perform well under varying environmental and mechanical stresses. Compliance with IS 16391:2015 highlights a manufacturer's commitment to producing high-quality geotextiles that contribute to the stability and longevity of pavement structures.

IS 16391:2015 – Geotextiles Used In Sub-grade Separation In Pavement Structures

This standard specifies the technical requirements and testing procedures for geotextiles used in sub-grade separation within pavement structures. It defines important performance parameters such as tensile strength, elongation, permeability, and durability. The geotextiles covered under this standard are required to have high resistance to mechanical stresses, including tearing, and to function effectively in providing drainage and separation between sub-grade materials. The standard ensures that the geotextiles used in pavement structures contribute to improving the structural integrity, load distribution, and overall performance of the pavement.

Benefits of BIS Certification for Geotextiles Used in Sub-grade Separation

BIS certification under IS 16391:2015 ensures that geotextiles comply with national quality standards, making them a reliable choice for use in pavement structures. For manufacturers, this certification boosts credibility, supports compliance with construction and environmental regulations, and promotes consumer trust. For end users, certified geotextiles provide assurance of their mechanical and environmental performance, ensuring the longevity and stability of pavement systems. Additionally, certification enhances the acceptance of geotextiles in construction projects, facilitating smoother approvals for infrastructure projects.
