Table 5.

Constrained modulus parameter ( $R_{M}$ ) for settlement calculations.

Conditions	Relationship for $R_{M}$	Notes
$I_{D} < 0.6$	$R_{M} = 0.14 + 2.36 \cdot l o g K_{D}$	clay soils
$I_{D} > 3$	$R_{M} = 0.50 + 2.0 \cdot l o g K_{D}$	clean Sands
$0.6 < I_{D} < 3$	$R_{M} = R_{M o} (2.5 - R_{M o}) \cdot l o g K_{D}$	silts to silty sands
	$R_{M o} = 0.14 + 0.15 \cdot (I_{D} - 0.6)$
$i f K_{D} > 10$	$R_{M} = 0.32 + 2.18 \cdot l o g K_{D}$
$i f R_{M} < 0.85$	$s e t R_{M} = 0.85$
