WebBrink et al. (Citation 1982) stated that a good soil must have its linear shrinkage value below 8% while Gidigasu (Citation 1974) put it as below 10%. All the soil samples fall below 10%; this is an indication that they can be utilized as base, subbase and subgrade materials. WebBulking is defined as the increase in volume of material when it is excavated from its in situ location. The change in volume is called ‘bulking’ and the measure of the change is the ‘bulking factor’.
