[amp_mcq option1=”More the value of group index, less thickness of pavement will be required” option2=”More the value of CBR, greater thickness of pavement will be required” option3=”Minimum and maximum values of group index can be 0 and 20 respectively” option4=”All of the above” correct=”option4″]<\/p>\n
The correct answer is D.<\/p>\n
Group index (GI) is a measure of the soil’s ability to support a pavement. It is determined by a laboratory test that measures the soil’s strength and drainage characteristics. The higher the GI, the better the soil’s ability to support a pavement.<\/p>\n
CBR, or California Bearing Ratio, is a measure of the soil’s ability to support a load. It is determined by a field test that measures the soil’s resistance to penetration. The higher the CBR, the better the soil’s ability to support a load.<\/p>\n
The thickness of a pavement is determined by the soil’s GI and CBR. The higher the GI and CBR, the less thickness of pavement will be required.<\/p>\n
Therefore, all of the statements are correct.<\/p>\n","protected":false},"excerpt":{"rendered":"
