Effect of Particle-Size Gradation on Coarse Sand-Geotextile Interface Response in Cyclic and Postcyclic Direct Shear Test

Table 1

Main characteristics of the geotextile.

Geotextile	Mass per unit area (g/m^2)	Trapezoidal tearing strength (kN/m)		Elongation at break (%)		Ultimate tensile strength (kN/m)
		TD	LD	TD	LD	TD	LD
Woven geotextile	150	0.4	0.4	28	28	20	28

TD, transverse direction; LD, longitudinal direction.
