The volume of voids in soil is related to the percentages of sand, silt and clay (soil texture) and to the arrangement of these soil particles soil structure. The texture and structure of soil determine the size and distribution of the pores and the total porosity of the soil. This empty space in soil enables root growth, water retention ...

An increase of 5 to 8 percent in sand moisture can result in a volume expansion ranging from 20 to 40 percent in dry sand. Additionally, finer sand exhibits a more pronounced increase in volume compared to coarse sand. Notably, bulking of sand is maximum if moisture content is about 4 - 6%.

Normally the CBR value of 2.5 mm penetration which is higher than that at 5 mm penetration is repeated as CBR value of material; But, if the CBR value at 5 mm is greater than at 2.5 mm penetration, repeat the test. If again test gives similar result then the higher value at 5 mm is reported as a CBR value of the material. Correction
