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?

AASHTO T 363 is one test method that evaluates stress development and cracking potential of cementitious materials. AASHTO R 101 identifies the AASHTO T 363 test for measuring shrinkage and expansion of cementitious materials from the time of casting. Therefore, AASHTO T 363 can perform elements of the topic ask. However, the proposed solution will be judged of its own merit based on the criteria identified in the topic statement. The proposed solution may include test equipment for 1) performing AASHTO T 363, 2) measuring volume change from drying, chemical, and autogenous means concurrently, or 3) another type of test equipment suited for this purpose. The proposed solution should identify the types of shrinkage that can be measured with the proposed device (e.g., drying, chemical, carbonation, plastic, and/or autogenous shrinkage).
