Construction Equipment Methods A soil type displays a swell

Construction Equipment & Methods

A soil type displays a swell factor of 0.74 The volume of soil to be excavated (bank) is 5000 cy. Which of the following is a correct statement. 5000 divided by the swell factor = total cy to be hauled (Total cy to be hauled - 5000) divided by 5000 = swell percent The insitu volume to be excavated multiplied by one plus swell % = total cy to be hauled The bank volume multiplied by the swell factor is a number that has no value to the excavation contractor.

Solution

A cubic yard of earth measured in its natural position swells to more than a cubic yard after it is excavated. This occurs because of an increase in voids.

Swell is expressed as a percentage of natural volume, for example, if 10 yd³ in the ground becomes 13 yd³ after excavation, the swell factor is 30%.
