    2. Effect of Void Ratio and Confining Pressure on Volume Change: The initial void ratio of the soil specimen has a significant effect on the volume change during shear. Loose sands, having high initial void ratio, tend to decrease in volume, since they do not have any interlocking effect and permit closer particle movement during shear.

    Alternatives to Gravel Drainfields

    using gravel to ones using tire chips. Due to the higher porosity of tire chips, less ponding was recorded. In fact, tire chips increase the drainfield storage capacity by 30 percent because the void space between the tire chips is greater than the void space for gravel (60 percent for tire chips; 40 percent for stone). Several studies have ...
