Proof-rolling.
(OP)
Proof-rolling has often been suggested as an alternate method for compaction testing. If the material lift is 8-12", near optimum moisture and the compaction effort ( weight / amplitude / pattern ) is adequate, what criteria should be used for interpretation, with respect to material type; crushed top courses, pit runs, clays / silts, etc ?
I'd appreciate your input.

(1) identifying soft spots in the subgrade (of a road or building footprint with slab-on-grade) and
(2) ensuring a "uniform" density in the uppermost zone of the natural stratum.
It has never been done to obtain a specific degree of compaction. I've seen this specified and have always wondered why it is so - if you aren't happy with the material at the founding level, you shouldn't have designed for it to be at that particular level.
