How is the overlap for adjacent geogrid sheets determined?

The overlap for adjacent geogrid sheets is determined based on the trench width. This approach ensures that the geogrids are correctly positioned to provide optimal reinforcement and stability in the soil structure during asphalting or construction processes. By taking into account the width of the trench, the designer can optimize the profiles of the geogrids, allowing for effective load distribution and minimizing potential failures at the seams where the sheets meet. This method is crucial in applications where precise alignment and sufficient overlap are necessary to maintain structural integrity under various conditions, such as heavy traffic or shifting soil.

While a fixed length of overlap might simplify standards, it does not cater to the specific requirements of different project sites. Similarly, while certain types of geogrids may have unique characteristics, the fundamental determination of overlap should align with trench dimensions to ensure the most effective installation. Avoiding overlap entirely is not a practical approach, as it can lead to weakness at the joints between sheets. Therefore, considering trench width offers a tailored solution that supports the geogrid's function and enhances overall performance in geotechnical applications.
