GEOGRID REINFORCEMENT OF FLEXIBLE PAVEMENTS: A PRACTICAL PERSPECTIVE

Geogrid reinforcement has been used in the design and construction of pavements for more than a decade, yet there exists no design method incorporating geogrid mechanical properties as direct design parameters. Because of the complexity of layered-pavement systems and loading conditions, there may never be a simple design method identifying the properties of a geogrid as direct design parameters for reinforced-pavement systems. Rather, a series of performance-based tests should be conducted to evaluate the structural contribution of geogrid reinforcement to pavement systems, from which design parameters could be derived and incorporated into a design methodology. This paper presents a practical perspective to address a modified American Association of State Highway and Transportation Officials (AASHTO) design method for reinforced pavements, performance tests to support and verify the design parameters, and cost-benefit and constructability analyses. Performance data and analyses presented are limited to multilayered-polypropylene-biaxial geogrids.
