Eric, thanks for the reference.
It reminded me of when I was still based in Chicago, and we used In-Stu Soil Testing (Roger Failmezger) out of Virginia to some work in East Dubuque, IL involving dilatometer testing at discrete intervals, pressuremeter testing at discrete intervals at locations near to the dilatometer test "holes", and piezocone readings at the same locations as the pressuremeter. The company has a rig that (obviously) can do CPT and DMT.
The really cool thing was that the pressuremeter was in-line behind the CPTu - thus minimizing the amount of stress relaxation in the sandy soils that we were sampling. We ended up getting way higher soil modulus and effective friction angle values than were suggested by published correlations with SPT N-values.
We were fortunate that the DOT was open to this sort of "nonstandard" testing.
