Direct shear test indicated that nonwoven geotextile system developed interface friction value similar to the gravel alone, while the slit film and heavyweight woven systems generated friction angles about 20 percent lower. Model test on similar pavements systems showed that, in terms of rut depths, the nonwoven performed better than the slit film woven geotextile for all gravel thicknesses. For all tests, geotextile anchorage was observed to be unimportant, as the geotextile appeared to be stretched only within the distributed load area at that location.
