Technical Committee

The Technical Committee continues to work with INDOT on CAPP issues and other specification concerns as they appear. This committee has been very proactive in pushing for needed changes in INDOT specifications that will benefit the majority of IMAA members. To do this, they have developed “small group” meetings with INDOT to work specifically on these needed changes. The small group sessions occur 3-4 times per year.  The overall industry committee meets 4-5 times annually and additional meetings are scheduled when needed.
