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 […]

Modeling demonstrates benefit of geogrid-reinforced aggregate base

December 21st, 2018

Improved modeling of geogrid for use with the Minnesota Department of Transportation’s pavement design software, MnPAVE Flexible, will allow pavement designers to simulate field tests of stiffness and resiliency in pavements over bases with and without geogrid. The department, known as MnDOT, is using modeling results from a recent study to develop a design input that quantifies the […]
