To assess construction quality and establish process control specification limit, governing organizations can use statistical analysis in materials sampling and testing. Inspecting costs and construction time-delays can be minimized with the assistance of statistical theory applications to establish the degree of variability for various items of highway construction. To illustrate the application of statistical theory to defining the variation in current construction projects in Prince George's County, MD., statistical estimates were made of hot-mix bituminous concrete and embankment construction. Estimated of arithmetic mean and standard deviation were made.
