CAPP Technician Resources

The Indiana Department of Transportation (INDOT) has established a Quality Control/Quality Assurance (QC/QA) program for aggregates for the purpose of properly assigning the responsibility of manufacturing and overall improving the consistency of aggregates. The QC/QA program for aggregates requires that all aggregates supplied for INDOT use be supplied by a Certified Aggregate Producer. The Certified Aggregate Producer Program (CAPP) is a program whereby a qualified mineral aggregate Producer requesting to supply material to INDOT assumes all of the Plant site controls, and INDOT monitors the Producers production, sampling, and testing procedures. The CAPP requires that a Certified Aggregate Technician supervise all sampling and testing for process control.

The principal objective of the Certified Aggregate Technician Program is to provide the necessary training to Producer personnel so that they may administer the Quality Control requirements of CAPP. Knowledge of aggregate production, materials, sampling, testing, statistics, and documentation are provided.
