CALIFORNIA'S EXPERIENCE WITH THE USE OF STATISTICAL SPECIFICATIONS

This paper presents a summary of California's experience with the use of statistical specifications for the control of highway construction quality. The paper outlines the research, initiated in early 1965, emphasizing the need for statistically based specifications. The early development of a moving average specification, the problems resulting from its implementation, and later revisions to the original specification are discussed. A subsequent study, initiated in 1972, comparing materials quality control under the orginal moving average specification with that derived from the previous finite limit specifications is also discussed, and the findings of the investigation are summarized. The conclusions of these studies are: The moving average specifications work well and are thought to be practical, and that administrative problems preclude the use of purely statistical based specifications.
