AASHTO M 288-21 PDF Download

The AASHTO M 288-21 standard is a comprehensive guideline for the selection, manufacturing, and implementation of geotextiles in various highway applications. Geotextiles are used for functions such as subsurface drainage, separation, stabilization, erosion control, temporary silt fence, paving, and soil reinforcement (including walls and slopes).

The standard emphasizes the importance of using geotextiles that meet specific physical, mechanical, and endurance properties. These properties ensure the effectiveness and durability of the geotextiles in their intended applications. The standard serves as a material purchasing specification, specifying the requirements that geotextile manufacturers must adhere to.

While the standard includes elements of quality control and management within manufacturing processes, its primary purpose is to provide a recommended design document. It offers guidance on selecting appropriate geotextiles for highway applications and assists in evaluating geotextile performance.
