  • Group Index Test Report

    1639 Words  | 7 Pages

    4.3.3 Group index To evaluate the quality of a soil as a subgrade material, the Group Index (GI) is also used along with the groups and subgroups of the soil. Group index is a function of the liquid limit, plasticity index, and the amount of material passing the 0.075mm sieve. A group index of 0 indicates a “good” subgrade material and a group index of 20 indicates a poor subgrade material (AASHTO, 2000). Group index is calculated using the following formula. GI = (F-35) [0.2 + 0.005(LL-40)] +

  • Consolidation Test

    786 Words  | 4 Pages

    Short Summary The aim of this experiment is to determine the rate and magnitude of compression of the soil. This is achieved by the displacement of water content in a given saturated soil sample when subjected to a load. By studying its rate and magnitude of compression, its preconsolidation pressure, compression index, recompression index and coefficient of consolidation can be calculated. Having the preconsolidation pressure helps determine the maximum vertical loading the soil can withstand before

  • Advantages And Disadvantages Of Refraction Of Light Through Different Media

    1643 Words  | 7 Pages

    Refraction of light through different media Light travels in waves through space in straight lines. In a vacuum the speed of light is 3x10⁸m/s, when light travels through denser mediums, it will change speed depending on its density. If light travels through a medium at a right angle, it’s velocity will change but not the direction. However if light enters the medium at an angle, both it’s direction and speed will change. For example if a ray of light (known as the incident ray) travels at an angle
