Abstract:
The North Carolina State Highway Commission lists ready-mixed concrete plants approved as sources of concrete for state highway work on the basis of periodic checks by its engineers and inspectors. Ratings of plants on the approved list are based on plant equipment and layout and on qualifications of the plant employees. An inspection classification further indicates whether there is need for close scrutiny by the consumer, or if the plant may be trusted to apply conscientious control of quality and uniformity. Materials used by the approved plants are inspected and tested by highway commission facilities, and a training program qualifies plant employees as concrete technicians.
