GSI to host webinar on geosynthetics used in paved and unpaved roads

June 7th, 2021

Beginning in the 1930s, geotextiles and then geogrids have been used in unpaved and paved roads for the purposes of reduced stone base thicknesses and improved serviceability. For use as unpaved road reinforcement, the theory is developed to the point that the benefit/cost of using geotextiles or geogrids can be assessed. This application is very […]
