Synthesis of Information Related to Highway Practices. Topic 57-18. Practices Related to the Use of Geosynthetics and Pavement Foundations

In recent years, the geosynthetic industry has introduced new products and techniques, intended to improve pavement performance and longevity. However, it is unclear how geosynthetic solutions (emerging and established) are being implemented in practice by state departments of transportation (state DOTs). A synthesis documenting current practices in the use of geosynthetics for pavement foundations can help state DOTs achieve durable pavement foundations and improve asset performance. The objective of this synthesis is to document current state DOT practices for the use of geosynthetics (e.g., geotextiles, geogrids, geocells, and geocomposites) for pavement foundations. This synthesis will encompass practices throughout the planning, design, construction, and maintenance/rehabilitation stages.
