Why Is Geogrid Aperture Size Important?
Geogrid aperture size is critical when selecting a product because it directly affects the performance and effectiveness of the interlock system. Geogrid is used in civil engineering and geotechnical applications to reinforce soil and materials such as aggregate layers.
The primary function of geogrid is to provide bearing capacity by distributing loads over a wider area. In an interlock system, geogrid prevents lateral aggregate movement and improves the integrity of the pavement structure.

A geogrid aperture is the opening or spacing between grid elements. It determines the size of aggregate or particles that can interlock with the geogrid. Selecting a suitable aperture is essential to ensure interlock and load transfer between the geogrid and aggregate.
If the geogrid apertures are too wide, small aggregate or particles may pass through them. This reduces the effectiveness of the interlock system and can compromise structural integrity and aggregate bearing capacity. Large apertures can also allow excessive aggregate movement, causing rutting, settlement and pavement instability.

Conversely, if the apertures are too small, they can hinder interlock by restricting aggregate movement. This can prevent the aggregate from engaging with the geogrid and reduce the geogrid’s ability to transfer loads over a wider area.
Therefore, choosing an appropriate aperture for aggregate interlock is essential for load transfer, interlocking and stability. It should be determined from the particle size of the aggregate while considering the desired interlock system, working loads and design specifications.
