Textiles - Geotextiles used in sub-grade separation in pavement structures

1. Summary about Geotextiles Used in Sub-grade Separation in Pavement Structures

These geotextiles are used to separate sub-grade soil from aggregate layers in pavement structures. They prevent intermixing of materials, improve load distribution, and extend pavement life.

2. Why BIS Certificate is Mandatory for Geotextiles Used in Sub-grade Separation

BIS certification is mandatory to ensure tensile strength, filtration properties, and durability required for long-term pavement performance.

3. What is BIS Certified for Geotextiles Used in Sub-grade Separation

BIS certification verifies compliance with Indian Standards covering tensile strength, elongation, permeability, and puncture resistance.
