I have a contractor who is claiming to have put 320 CY of CTB in an area that called for 240 CY. I have his haul tickets to verify the amount of CTB he placed and a representative onsite that verified that little to none of the material was wasted. I have a topo of the area's subgrade and though the subgrade was not perfect, it does not account for that large of an overrun. Am I missing something ? Can CTB shrink by 25% when compacted to a density of 98 % at 1 foot in depth ? I can not seem to come up with a reasonable explanation of how this is possible.
