A proposed ASTM International standard will provide guidance for using geocells—open-celled geosynthetics that help hold soils and rocks in place—in roadway projects. Geocells are commonly used in road construction, earth retention and other construction projects.

According to ASTM International member Eli Cuelho, there is currently no standard for using geocells in geotechnical and roadway projects. “The proposed standard will bring a more unified understanding of the most efficient and appropriate ways to use this type of ground-improvement technology to a variety of geotechnical applications,” said Cuelho.

Geocells support slope stability, erosion control, retaining walls, channel protection, pavement load support and subgrade improvement, he said. The proposed standard will give engineers and owners information on key design principles, properties and methodologies for using geocells.

ASTM International’s geosynthetics committee (D35) is developing the proposed standard (WK61159).

Cuelho said this effort relates to the United Nations Sustainable Development Goal #9 on industry, innovation and infrastructure.
