STATISTICAL QUALITY CONTROL PROCEDURES

The purpose of the study was to recommend changes in materials specifications and construction control procedures based on improved statistical procedures. The results of construction-control tests were obtained from 30 airport construction projects and analyzed to determine the typical distributions of the data. Criteria used in selection of the project data were that the contractor be reputable and capable and that the completed job be considered satisfactory. For this, the recommendations of FAA and CE personnel associated with the construction were used. The Data collected included pertinent properties of subgrade, lime-treated subgrade, subbase, base, asphalt concrete, and portland cement concrete; however, data on all of these materials were not available at every construction site. The data were analyzed to determine the average and standard deviations of each parameter, and these were, in turn, used to recommend allowable maximum deviations from the average for inclusion in the applicable specifications. The requirements for the recommended specifications were determined with two primary considerations: (a) that a quality pavement be constructed and (b) that the specifications be realistic. The statistical quality control procedures were developed for the various types of construction to include the most pertinent parameters pertaining to the quality of pavement. /Author/
