Flexible Knitted Gravel Driveway Geogrid

Gravel Driveway Geogrid Benefits:

· Reduces amount of aggregate needed= construction cost savings.

· Reduces soil excavation and backfilling= construction cost savings.

· Minimizes differential settlement and prevents upward movement of the subgrade = higher structural performance.

· Improves overall structural life= maintenance cost savings.

Characterization of Geogrid Reinforcement. 

Flexible Knitted Gravel Driveway Geogrid

The properties of geogrids relate to their ability to interlock with the base course material 

and provide confinement. Based on research by Kinney (1995) and Collin et al. (1996), 

the aperture stability modulus was the

stiffness property selected, based on correlation with measured performance in roads. The

aperture stability modulus is obtained by measuring the in-plane torsional behavior directly

across the junction of a biaxial geogrid. It is a direct measure of the in-plane stiffness and

stability of the ribs and junctions of the geogrid. The method was calibrated using data for

stiff biaxial geogrids with aperture stability modulus of 0.32 and 0.65 N-m/deg (Kinney,

2000). In the design method the aperture stability modulus can vary from zero to a

maximum value based on the data used in the calibration (Giroud and Han, 2004b). A draft

test method for determining the aperture stability modulus of a geogrid has been developed

by Kinney (2000) and a standard method is currently under development by ASTM.
