Low compaction of crushed limestone/fines
Low compaction of crushed limestone/fines
(OP)
A technician used a nuke on a material known as Ab3 or crushed limestone with fines. It's basically a collection of aggregates with a varying gradation and low plasticity. It's used in areas to improve stability of pavements or foundations.
The technician had failing tests of the 132 psf proctor and failed to retest before more material was placed. So they need to do another type of test to get more data to prove compaction of the material. Would a Wildcat DCP test be feasible? Further nuke testing is not possible.

I would remove the pavement surfacing and retest with nuke gage or sandcone. Any other method would be a guess...and not a good one.

Not sure where you are located, but some limestones/limerocks are not great for static fill such as this, particularly if you have high groundwater or acidic groundwater potential.
