The coefficient of curvature for a well graded soil, must be from-
1.0 to 3.0
Soil Type C_u Criterion C_c Criterion Well-Graded Gravel (GW) C_u > 4 1 \le C_c \le 3 Well-Graded Sand (SW) C_u > 6 1 \le C_c \le 3 As seen from the table, for both well-graded gravel and well-graded sand, the Coefficient of Curvature (C_c) must fall within the range of 1.0 to 3.0.
