It is determined using the following equation:<\/p>\n<p>GI = 0.007 * LL + 0.01 * PI + 0.007 * (F \u00e2\u0080\u0093 35)<\/p>\n<p>where:<\/p>\n<ul>\n<li>LL = liquid limit<\/li>\n<li>PI = plasticity index<\/li>\n<li>F = percentage passing 75 micron IS sieve<\/li>\n<\/ul>\n<p>In this case, LL = 40%, PI = 10%, and F = 35%. Substituting these values into the equation, we get:<\/p>\n<p>GI = 0.007 * 40 + 0.01 * 10 + 0.007 * (35 \u00e2\u0080\u0093 35) = 5<\/p>\n<p>Therefore, the group index for this soil is 5.<\/p>\n<p>The group index is used to determine the suitability of a soil for various engineering purposes. Soils with a GI of 0 to 4 are considered to be low plasticity soils and are generally suitable for most engineering purposes. Soils with a GI of 5 to 12 are considered to be medium plasticity soils and may be suitable for some engineering purposes, but may require special treatment. Soils with a GI of 13 to 20 are considered to be high plasticity soils and are generally not suitable for most engineering purposes.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[amp_mcq option1=&#8221;0&#8243;
