Cleveland OH, October 1, 2024 – According to the new Global Geosynthetics, global demand for geosynthetics in the transportation infrastructure market is expected to grow 2.7% annually to 2.9 billion square meters in 2028.
Worldwide, growth in transportation uses of geosynthetics is closely tied to the construction and maintenance of roads and highways:
- 1.5 million kilometers of paved roads are expected to be added between 2023 and 2028.
- In addition, the percentage of transportation projects incorporating geosynthetics will continue to rise, as more end users understand that these materials provide a cost-efficient means of increasing the lifespans and reducing the long-term maintenance costs of roads and highways.
- Growth will be further bolstered by the World Bank’s requirement that all infrastructure projects it helps finance must include geosynthetics to improve the lifespan of the installations.
Geotextiles in the Transportation Infrastructure Market Dominate
Although a number of geosynthetics find use in the transportation infrastructure market, geotextiles dominate due to their low cost, consistent performance qualities, and ease of installation. Growth will be supported by the continued use of geotextiles in separation applications and their increasingly common use in other applications, such as reinforcement, drainage, and erosion control. Geotextiles are also commonly used as filters in the construction of underdrains or as subsurface drainage systems under or near roads.
Other geosynthetics such as geogrids, geomembranes, geonets, geosynthetic clay liners (GCLs), geofoams, and erosion control blankets can be used with geotextiles to provide enhanced reinforcement, drainage, and the like. For example, geonet usage is expected to increase as more consumers become aware of the performance benefits of these materials, particularly their chemical resistance and ease of installation However, greater use of these materials is often at the expense of alternative geotechnical products, including soil and aggregates.
