Yes but not a formal written procedure. However we do not perform a CIR mix design for our projects. We have performed past research that has shown by project selection standard emulsion rates are acceptable. |

It is routinely used, and we have one specification that is used state wide but it is not a "standard specification" as NYSDOT defines the term. |
No, we have a traffic limit of 8000 AADT with 10% trucks or approximately 5 million 20-year ESALs. |
Yes, if it meets the traffic limits given above, but rarely maybe once every year or two. |
Yes, very frequently. Some years NYSDOT has over 40 CIR projects, Localities in New York have even more projects following our specification. |
No, but we are working on one with our industry, trying to tie emulsion content to stability. Our greatest problem with a set mix design, so far, is that emulsion content is also tied to mix workability and compaction in the field. |
