ISO 10318-1:2015/Amd 1:2018

Overview

ISO 10318-1:2015/Amd 1:2018 is an official amendment to the international standard covering geosynthetics terminology and definitions. Published by the International Organization for Standardization (ISO), this document provides updated and precise terms essential for professionals working with geosynthetics in engineering, construction, and environmental applications.

This amendment ensures clarity and consistency in the language used throughout the industry, facilitating better communication among manufacturers, engineers, project designers, and regulatory bodies worldwide.

Key Topics

The amendment introduces critical updates and additional definitions that expand the original ISO 10318-1:2015 standard, focusing on the following:

• Stabilization: Defined as the improvement of the mechanical behavior of unbound granular materials by incorporating one or more geosynthetic layers to reduce deformation and limit movement under load.
• Geoblanket (GBL): Described as a permeable structure consisting of natural or synthetic fibers bonded with geosynthetic elements, forming a continuous sheet useful in various engineering applications.

These enhanced definitions are pivotal in standardizing terms that describe how geosynthetics interact with soil and other materials to improve structural performance.

Applications

The terminology clarified in ISO 10318-1:2015/Amd 1:2018 is vital for multiple practical uses across geotechnical and environmental fields, including:

• Soil Stabilization and Reinforcement: Using geosynthetics to enhance the strength and durability of soil structures in roads, embankments, and retaining walls.
• Erosion Control: Application of geoblankets as protective layers to reduce soil erosion, promote vegetation growth, and manage water flow.
• Drainage and Filtration: Terms defining specific geosynthetic types help design efficient drainage systems integral to infrastructure longevity.
• Landfills and Environmental Protection: Clear definitions support the correct selection of geosynthetics for containment and barrier systems, ensuring environmental safety.

Accurate terminology fosters improved design accuracy, compliance with regulatory frameworks, and enhances international collaboration on geosynthetic projects.

Related Standards

ISO 10318-1:2015/Amd 1:2018 forms part of a comprehensive suite addressing geosynthetics, often referenced alongside:

• ISO 10318 Series – Covers different aspects of geosynthetics including materials, test methods, and performance criteria.
• ISO/TC 221 – The technical committee responsible for standards related to geosynthetics.
• ISO/IEC Directives – Guidelines for developing and maintaining international standards, ensuring uniformity and quality.
• Other environmental and geotechnical standards complementing geosynthetic applications in civil engineering.

Understanding and applying the updated terms from this amendment contributes to consistent international standards essential for advancing geosynthetic technologies.
