Effectiveness of Geotextiles/Geogrids in Roadway Construction

The objective of this project is to evaluate the performance benefit and cost effectiveness of geogrid in road systems by addressing five questions: (1) What strength enhancement is offered by the use of geogrids? (2) In which layer in a pavement structure is geogrid most effective? (3) How should geogrids be in the MnPave software application? (4) How would it be possible to evaluate the effectiveness and reliability of proprietary geogrid design? (5) How would it be possible to evaluate cost versus benefits of geogrids in different soil conditions?
