Abstract
Geogrid is a polypropylene material manufactured with approximately 1-in. wide openings, called apertures. A triaxial geogrid configuration is illustrated in Figure 1. Geogrid reinforcement is typically positioned beneath and/or within an aggregate base layer in a pavement structure and is designed to prevent lateral spreading of the individual aggregate particles comprising that layer. Thus, inter-particle friction can be increased among the individual aggregate particles located above and potentially below the geogrid. When this occurs, the result is an increase in the stiffness of the aggregate base layer that leads to a greater load-carrying capacity of the pavement.
