Who is the intended end user for this device?
As you say, there are few building contractors familiar with performing AASHTO T 363, so accelerating this test will not benefit those not currently performing it. Perhaps the cost benefit comes from reduced failures and maintenance costs? How will DOT evaluate the broad benefit from this new technology in terms of who will actually be using it.

Is AASHTO T 363 considered the “gold standard” that the new (faster, better, cheaper) technology will be required to correlate with?
If not, are there other standards or processes that capture the targeted shrinkage measurement?

are there test sites already designated for particular examples of concrete shrinkage issues?
it would help to have some particular examples or case studies of concrete shrinkage situations that demonstrate the issues that DoT is concerned with addressing, so that the measurement device is well-adapted to the application
