Concrete control Procedures for the Northern Illinois Toll Highway resulted in greater contractor efficiency, lower costs, and closer conformance to specification requirements than usually obtained on similar work. Supervision of the numerous contracts was effected by the section engineers, general consultant, and testing laboratories working in unison to insure quality of materials and uniformity of structural and pavement concrete. Semiautomatic batching and central mixing plants, which were equipped with automatic recording moisture meters, finish screens for coarse aggregate, and recorders to indicate batch weights, significantly contributed to the good control of concrete quality.
