Statistical Quality Control in Highway Construction
California's experience in making a statistical study of its quality specifications for highway and bridge construction materials is described. Four years of research on sampling and testing of materials such as compacted embankment, plastic concrete, cement treated base, structural concrete aggregate, untreated base material and aggregate subbase material is beginning to provide information concerning variations due to sampling, testing, and those inherent in the material itself. Suggested in place of traditional methods is Statistical Quality Control (SQC). The use of SQC could shift the quality control responsibility to the contractor with the buyer basing his purchase on a statistically sound end point evaluation. Problems arising in the use of SQC may be met by training in the technology of statistical control, recognition of the fact that there is no need to supply statistical specifications to every construction item, the establishment of new specification limits, and a revision of testing procedures.
