The Aggregate Quality Control/Quality Assurance Program is designed to give aggregate producers more responsibility for controlling the quality of material they produce and to utilize the quality control information they provide in the acceptance process by the North Carolina Department of Transportation (NCDOT). It requires aggregate producers to perform quality control sampling, testing and record keeping on aggregates that they ship for use by the NCDOT. Also, it requires the NCDOT to perform quality assurance sampling, testing and record keeping to confirm the performance of the producers' control plan as set forth herein.

The program has two sections.

Section I of this program is designed for Aggregate Producers providing Clean Coarse or Fine Aggregates for use on or in products such as asphalt, concrete, block, etc., that are utilized on NCDOT right of way. Asphalt sand that is produced by and utilized by the same asphalt producer shall be tested according to the provisions of the Hot Mix Asphalt Quality Management System Manual.

Section II of this program is designed for Aggregate Producers providing any type of Aggregate Base, including Cement Treated, material that is utilized on any type of NCDOT Maintenance or Contract project whether purchased by a Contractor or sold directly to NCDOT.

It is the intent of the program that acceptance or rejection of material be based on the total program. Therefore, a comparison of the Quality Control, Quality Assurance, and other sample data may be used by the NCDOT for acceptance or rejection of a lot of material.

The basic requirements for approval to participate in the program are:

Participation in the program does not relieve the producer of the responsibility of complying with all requirements of the NCDOT Standard Specifications for Roads and Structures.
