Geogrids
have
been widely used to reinforce paved and unpaved roads constructed on soft subgrade. To quantify the effectiveness of geogrids
in
low-volume flexible pavements when constructed on weak subgrade The evaluation included transverse profile measurements. The study found that reinforced pavement sections experienced less rutting
than the unreinforced sections. Observations of the pavement cross section profile, through trenches dug after the testing was complete, confirmed that pavement failure was mainly due to subgrade
shear.
