AN EXAMPLE OF EXTREMELY LOW SOIL CONVERSION FACTOR

Abstract

The earthwork for railroad embankment had to be suspended when a serious shortage of fill material was suddenly apprehended. The completed section of embankment and the fill material that remained untouched at borrow pits were thoroughly investigated with a dynamic penetrometer and the conclusion has been reached that a lower soil conversion factor of the fill material than estimated for design purpose is largely responsible for the heavy shortage of the fill material.
