Please help me find a brief history of Recycled Concrete Aggregate (RCA) CLASSIFICATION in the U.S. any paper or Official U.S. state DOTs' document.
Target:
To find out how many classifications of RCA we have and what is the difference?
Thank you all.
Have a look at https://psnet.ahrq.gov/primer/root-cause-analysis
Article Survey on Models and Techniques for Root-Cause Analysis

I am the current Chair of the ACI 555 committee on Recycled Materials in Concrete. We are close to finishing a technical report on RCA that captures pertinent aspects in a comprehensive manner. Unfortunately, I cannot predict when exactly it will be approved and published.
I can give you informations on the classification of recycled aggregates in Germany. We have 4 types. 2 of them are allowed in constructive, load bearing concrete in limited portions. More information you can found in
https://youtu.be/_D9r9w2S0hc or in my book "Baustoffrecycling" in German. I just preparing in English version.
I would be interested in U.S. classification to.
